Heinrich d'Arrest discovered NGC 1 on 30 Sep 1861 while testing the 11-inch f/17.5 Merz refractor of the Copenhagen Observatory.  He missed nearby NGC 2.  This was d'Arrest's first deep sky discovery, though he was uncertain if his object was identical to h4 or h5 (both of which refer to NGC 16).  His descriptions (combination of 4 observations) read "faint, small, round, 20", no concentration.  In a straight line connecting two stars 11 and 14 mag."  Herman Schultz observed NGC 1 three times in 1866 and 1868 with a 9.6-inch refractor at Uppsala and he also missed fainter NGC 2.  The NGC 1 and 2 pair are not physically related. NGC 1 lies at a distance of ~200 million l.y. with NGC 2 at roughly 320 million l.y.

NGC 2 was missed by d'Arrest, who discovered NGC 1 on 30 Sep 1861 with an 11-inch refractor, and Herman Schultz, who observed NGC 1 with the 9.6-inch refractor at Uppsala.  Yann Pothier credits Auguste Voigt with the original discovery on 14 Sep 1865 with the 31-inch Foucault reflector at the Marseilles Observatory.

Lewis Swift found NGC 6 = Sw. 2-3 on 20 Sept 1885 with the 16" Clark refractor at Warner Observatory and recorded "eF; cE; vS; one of 5 stars which point to it is pretty near."  There is nothing at his position, but 75 seconds of RA east and 47' north is NGC 20 = UGC 84.  The RA offset is shared by several other objects discovered this night (NGC 19, 21, 7831, 7836) though the declination error is much larger (8' for the other objects).  But his description matches the chain of five stars just following NGC 20.  So, it is nearly certain NGC 6 = NGC 20 (discovered by R.J. Mitchell using LdR's 72" on 18 Sep 1857). The RNGC misidentifies NGC 6 as NGC 7831. See Corwin's notes for more info.

MCG misidentifies MCG +04-01-030 as NGC 8.  Although the RNGC New Description reads "looks like double star", the classification is a galaxy.  HyperLeda (as of 2016) also misclassifies this object as a galaxy.

William Herschel probably discovered NGC 16 = H. IV-15 = h4 = h5 on 8 Sep 1784.  He recorded "Stellar, or rather like a faint star with a small chevelure and two burs [sic].  F, S." His RA was 1 min 24 seconds too large (using a different star Corwin found an error of 1 min 6 seconds).

 

John Herschel observed this galaxy on 5 Sep 1828 and described h4 as "pB; R; bM; 30" (? if not IV. 15)"  Due to the difference in position he wasn't sure if his object was new.  John Herschel swept the area again 11 nights later and found a nebula (h5) that he assumed was his father's H. IV-15: "a star 15m with a burr, RA from Catalogue."  Édouard Stephan made several observation, apparently trying to find two different objects as reported in the General Catalogue (GC 8 and 12). In the NGC, Dreyer combined the previous designations into NGC 16 and Corwin favors this interpretation. Wolfgang Steinicke feels H. IV-15 more likely applies to NGC 22 than NGC 16.  Herschel's RA was off by 40 seconds (too far east) and 7' too far south but the description "F, S, Stellar, or rather like a faint star with a small chevelure and two burs" may be a better fit. 

 

J.L.E. Dreyer, observing with the 72" on 29 Oct 1877, recorded "pB nucl with vF neby; round; E sp nf; 2 st 13 and 12 mag preceding in the parallel about 4' and 5' distant."

Frank Muller discovered NGC 17 = LM 2-276 in 1886 and logged "mag 13.5, 0.1' dia, irregularly round, two stars mag 9.5, 2.0' in PA 280°."  Muller's position was 2.0 min of RA west of PGC 781 (typical error found in Leander McCormick observations) and his description of the nearby double star 2' west clinches the identification.

 

This galaxy was independently found by Lewis Swift (Sw. 6-1) on 21 Nov 1886 (same year) at Warner Observatory and catalogued as NGC 34.  Herbert Howe noted the identity NGC 17 = NGC 34 (Mon. Not.

Lewis Swift discovered NGC 19 = Sw. 2-4 on 20 Sep 1885 with the 16" refractor at Warner Observatory. His description reads, "eeF; lE; in [the] center of 3 vF st forming an equilateral triangle, two of them double."  There is no obvious candidate at Swift's position but 74 seconds of RA east and 8' north is UGC 98.  Similar offsets in RA and Dec yield identities for NGC 21, 7831 and 7836, all discovered the same night (NGC 6 also shares the same offset in RA).  Furthermore, his description of the surrounding stars matches this galaxy.  Hermann Kobold suggested this identification when he measured its position in 1898 at Strasbourg with the 18-inch refractor.  Heber Curtis found it again on a photograph taken with the Crossley reflector in 1912-13 and reported it as new ("not noted in the NGC).

 

NGC 19 is mislabeled as NGC 21 in RNGC, PGC and UGC (and software Megastar) and not assigned a NGC designation in MCG and CGCG.  Finally, RNGC misclassifies NGC 19 as nonexistent because of the error in Swift's position.  See Corwin's Notes.

R.J. Mitchell discovered NGC 20 using Lord Rosse's 72" on 18 Sep 1857 and recorded as "S; R; pB; bM").  Although no position was measured it was catalogued as GC 6 (Rosse nova) and later by Dreyer as NGC 20.  Herman Schultz independently found the galaxy on 16 Oct 1866 with the 9.6" refractor at Uppsala and it was entered by Dreyer in the GC Supplement as GC 5086, though Dreyer added the comment "Query = GC 6".  Schultz's micrometric position matches UGC 84.

 

Lewis Swift later independently found this galaxy on 20 Sept 1885 and published it in his second discovery paper (#3).  Swift's position for NGC 6 was 1.1 minutes of RA west and 47' S of UGC 84.  His RA offset is identical to the error in his positions for NGC 19, NGC 21, NGC 7831, NGC 7836, all found the same evening.  Although the dec error is large, his description ("one of 5 st which point to it is p nr") matches the chain of 5 stars just following, so NGC 6 is a duplicate of NGC 20 (primary designation).

Lewis Swift discovered NGC 21 = Sw. 2-5 on 20 Sept 1885 and recorded "eF; S; lE."  His positions for NGC 19, 7831 and 7836 from the same evening are all offset ~70 seconds in RA and 8' in declination.  The offset position for NGC 21 lands on NGC 29.  So, NGC 21 is a duplicate of NGC 29.  RNGC, UGC and PGC misidentify UGC 98 = NGC 19 as NGC 21.  See NGC 19.

Édouard Stephan discovered NGC 22 = St. 13-1 on 28 Sep 1867 with the 31" reflector at the Marseilles Observatory.  On this date he only wrote a rough position for NGC 16 in his logbook but gave an offset (38 seconds of RA and 5' dec) to NGC 22.  He observed NGC 22 again on 29 Oct and 1 Nov 1877 and published an accurate position (reduced on 2 Oct 1883) with description "eF; pS; R; little brighter middle, resolvable".

 

William Herschel possibly discovered this galaxy on 8 Sep 1784 (H. IV-15, sweep 260) and recorded "F, S, Stellar, or rather like a faint star with a small chevelure and two burs."  His position is poor -- 40 sec too far east and 7' too far south -- but the description is a reasonable fit.  Dreyer assumed the observation referred to NGC 16, which is 1 min 25 sec of RA to the west and he commented in the NGC notes "Some error in recording the transit, probably simply of 1 min; reductions correct."  Wolfgang Steinicke feels H. IV-15 refers to NGC 22 and Herschel never observed brighter NGC 16, but Corwin and Seligman favor Dreyer's interpretation.

William Herschel discovered NGC 29 = H. II-853 = h6 on 26 Nov 1790 (sweep 981) and noted "F, S, E nearly in the meridian."  John Herschel called it "pB; pL; irr figure."  Swift found the galaxy on 20 Sep 1885 and recorded it as new in his second discovery list (#5).  His position was offset  by 70 seconds of RA too far west and 8' in declination, so Dreyer assumed it was a different object and catalogued it as NGC 21.  But Swift's position for NGC 19, 7831 and 7836, all discovered on the same night, carry this same offset.  So, NGC 21 is a duplicate observation of NGC 29.  NGC 29 was observed 8 times with Lord Rosse's 72" and recorded on 16 Oct 1854 as "Elongated north and south, * at on end of neb inv, and another rather fainter south of center."

John Herschel discovered NGC 31 = h2311 on 28 Oct 1834 and logged "eeF; the following of 2. Requires attention, but leaves no doubt" and on a later sweep as "eeF; S; R." The preceding object is h2310 = NGC 28.  Herschel's positions clearly establishes NGC 28 = PGC 730 and NGC 31 = ESO 149-020 = PGC 751.  Nevertheless, the PGC reverses the identifications of NGC 28 and 31.  The galaxy identified in the RC2 as NGC 28 is actually NGC 31. The ESO entry (149- G20) for NGC 31 does not give the NGC equivalence. The SGC (Southern Galaxy Catalogue) identifications are correct although the PGC errata paper claims the SGC reverses the identifications.

Lewis Swift discovered NGC 34 = Sw. 6-1 on 21 Nov 1886, along with NGC 35, with a 16" refractor at Warner Observatory.  His position and description ("equilateral triangle with 2 stars, one a close double") matches MCG -02-01-032 = PGC 781.  Frank Muller independently found this galaxy in 1886 and listed it as LM II-276 (later NGC 17).  His RA was 2.0 minutes too small, but the description matches.  So, NGC 34 = NGC 17 (discovery priority unknown).  Herbert Howe searched for NGC 17 unsuccessfully with the 20" refractor at Denver and concluded it was equivalent to NGC 34 based on the similar descriptions.

48" (10/23/14): this showpiece, annular planetary was observed unfiltered (low-excitation) at both 488x and 813x, and a remarkable amount of structure was seen .  The main body of NGC 40 was nearly round and 0.7' in diameter but outer extensions on the north and south ends increased the dimensions to roughly 1.0'x0.8' SSW-NNE.  The darker interior surrounding the blazing mag 11.5 central star (WC8-type carbon Wolf-Rayet) had a very uneven surface brightness and was slightly darker SW of the central star.

 

The rim was irregular and much brighter along fairly narrow N-S strips on the W and E side.  The western rim was the brighter of the two and somewhat patchy with a slightly darker notch to the south of its center.  At its N end was a small, faint extension. The rim was more uniform in brightness on the E side.

 

A very faint, thin outer loop curled N and W at the north end of the main disc!  A small, detached, elongated patch floated near its N edge, but slightly S of the tip of the outer loop to its east. A very faint star or stellar knot is involved in this patch.

 

The rim was very weak on the S side and an easy star was visible at the SW end.  A faint, very small detached piece was easily visible at the southern extremity [32" SSW of the central star] of NGC 40.  This patch forms the E vertex of a small triangle with the star ~10" NW (noted earlier) and a fainter star 10" SW. 

 

17.5" (12/30/99): at 100x appeared (unfiltered) as a slightly elongated, moderately bright disc surrounding a bright mag 11.5 central star. A slightly fainter mag 12 star lies 1.0' SW.  This is a low excitation PN with an OIII/H-beta ratio of just 0.4 and at 100x there was a noticeable enhancement using the H-beta filter, while it dimmed with an OIII filter.  At 220x, a star was intermittently visible at the SW edge and the PN was slightly elongated SSW-NNE.  The UHC filter gave the best response at this power.  The surface brightness appeared irregular -- darker around the central star and slightly brighter along the west and east side of the rim.  At 280x, the faint star I noted earlier was barely off the SW edge and the PN was weakly annular with a brighter rim along the west and east side and a darker center.  The SW and NE ends of the halo were clearly weaker, though.  380x provided a nice view with subtle irregularities in the interior.

 

17.5" (11/1/86): bright, moderately large, round.  Contains a prominent mag 11.5 central star surrounded by a fairly bright halo.

 

13.1" (12/7/85): at 166x (unfiltered): bright central star visible centered within a fairly small prominent disc.

 

13.1" (1985): moderately large, bright central star surrounded by a moderately bright halo at 166x and 214x using a UHC filter.

 

8": at 100x; a bright central star is surrounded by an easy halo.

 

William Herschel discovered NGC 40 = H. IV-58 = h8 on 25 Nov 1788 (sweep 886).  He recorded, "a star about 9th mag [central star], surrounded with very faint milky nebulosity; other stars of the same size are perfectly clear from that appearance. The star is either not round or double; but I am in the north and above the pole, I could not view it sufficiently to determine it. Less than 1' in diameter."  He used NGC 40 in his 1791 PT paper as one of several examples where the association of the nebula and star was unquestionable.

 

On 20 Nov 1829 (sweep 228), John Herschel described it as "a star 11m with a luminous atmosphere 30" to 40" diameter."  On 29 Oct 1831 he noted "a * 10m with strong nebulous atmosphere 15" diameter.  Exactly round and pretty suddenly fading away makes a double star class 5 with a star preceding."

 

Williamina Fleming first noted the bright emission spectrum in 1905: "Five bright lines or bands appear in the spectrum..[but] the nebular lines near wavelength 5000 are not seen."  Based on Crossley photographs, Curtis (1918) described, "Central star about mag 10.  The nebula resembles a truncated ring from the ends of which extend much fainter wisps.  The brighter central portion is 38"x35" in PA 14°, while the total length along this axis is about 60"."

30" (11/4/10 - Coonabarabran): NGC 55 nearly filled the 37' field of the 21mm Ethos at 264x, extending close to 30' in length WNW-ESE and roughly 4' in width.  The structure was fascinating at 429x with a highly irregular surface brightness due to dusty patches and rifts, along with bright clumps and knots. The "bright" central section, which is offset WNW of center, spans ~9' in length.  At the west end of the central section, the surface brightness dims significantly, and the galaxy tapers, extending several arc minutes further WNW. On the east side of the central region is the "core" (cataloged as HII region [HK83]#17-19). It appeared ~1' in length and bright, elongated, mottled, and slightly bulging.

 

Just ESE of the core are two noticeable, elongated knots; the first, [WS83]#1, is small, while the second knot, [HK83]#14, is very bright and elongated. With careful viewing the second knot resolved into two individual pieces or clumps. Continuing further ESE, the surface brightness abruptly drops significantly, and a large, elongated dark notch appears to take a bite out of the galaxy. Just as the galaxy begins to brighten again, there is another bright round knot [HK83]#10 with a very small piece just detached to its SE. The ESE extension of the galaxy brightens a bit more and has an irregular, patchy appearance, with a couple of brighter stars (mag 12.0 and 13.7) superimposed along the S edge.

 

20" (7/8/02 - Magellan Observatory, Australia): viewed at nearly 60° elevation at 212x, this huge galaxy was an amazing sight and overfilled the 23' field (at least 25' in length).  Near the core were two small, prominent HII knots ([HK83]#14 and [WS83] #1). A couple of additional low surface brightness knots, [HK83]#10, were visible further east along the mottled extensions. The appearance was asymmetric with the brighter WNW section bulging slightly.

 

17.5" (11/1/86 and 12/3/88): very large, edge-on 6:1 WNW-ESE, 16'x3'.  Very asymmetric with a bright, elongated western portion, darker center and a faint, nearly detached eastern section (IC 1537). Faint stars are involved at the west side. The eastern portion appears tilted at a slight angle to the main western portion. 

 

13.1" (11/5/83): fairly bright, very large.  The very faint eastern portion is near detached from the bright WNW section.

 

8" (9/25/81): very large, very elongated, brighter to the west, very faint eastern section.

 

15x50 IS binoculars (10/21/06): although very low in the southern sky, NGC 55 was visible as a faint, relatively large elongated patch using handheld IS binoculars. NGC 55 is easy to locate 3.8° NW of Alpha Phe as the galaxy is exactly collinear with three mag 7 stars to the east that are aligned from east to west.

 

James Dunlop discovered NGC 55 = D 507 = h2315 on 7 Jul 1826 from Parramatta, New South Wales.  Using his 9-inch f/12 speculum reflector, he described it as "a beautiful long nebula, about 25' in length; position N.p. and S.f., a little brighter towards the middle, but extremely faint and diluted to the extremities. I see several minute points or stars in it, as it were through the nebula: the nebulous matter of the south extremity is extremely rare, and of a delicate bluish hue. This is a beautiful object."  Dunlop observed the galaxy on 4 nights and made a simple sketch (Figure 21).

 

John Herschel first observed this galaxy from the Cape on 3 May 1834: "bright; very large; very much elongated in a long irregular train, the preceding end being much the brightest. Whole length = 1.5 diam. of field, or 22' The nucleus is either a double star or a much more sharply terminated nebulous mass, elongated in a different position (146.5 ) from that of the nebula (109.8 )." He observed it again on 23 October 1835, recording it as "very bright; very large; very much elongated; at least 25' long and 3' broad. The following part is faint, the preceding and shorter trinuclear the 2d, nucleus taken. A strange object." His final observation on 4 October 1836 reads: "very bright, very large; a very long irregular crooked ray with 3 nuclei, the second of which appears to consist of stars." His sketch of the galaxy (fig. 8, plate IV) clearly shows its convoluted form and three brighter sections. In his discussion, he grouped it together with the galaxy NGC 300 and the star cluster NGC 1950 as "nebulae of irregular forms having a tendency to several centres of condensation; in the case of [NGC 1950] but little conspicuous - in that of [NGC 55] (otherwise remarkable for its extravagant length and crooked shape) much more so, while in [NGC 300], the formation of separate nuclei is decided, the intermediate faint nebula barely sufficing to mark them as forming a connected system."

 

Joseph Turner sketched NGC 55 using the 48" Great Melbourne Telescope on 29 Oct 1875 (plate I, figure 2 in "Observations of the Southern Nebulae made with the Great Melbourne Telescope from 1869 to 1885").  He reported "The present appearance agrees well with H.'s description and drawing. The 'following' portion is now much fainter than shown by H.'s sketch; indeed it is so very faint that its exact outlines cannot with certainty be determined, a faint whitishness being all that can be made out, while the star-like appearance described by H. in his portion cannot now be seen. The 'preceding' portion is still, as shown by H., much the brightest. There are still three nuclei, the centre one of which is much the brightest. H. says this one appears to consist of stars; but although I have tried several powers, I cannot with any certainty, determine this point, although it has, at times, a sparkling appearance. The 'following' portion of this nebula appears to have become much fainter since H. observed it."  Turner's sketch shows the bright knot on the eastern end of the galaxy.

 

Lewis Swift reported the eastern section (Sw. 11-2) as a new object: "eeeF; vL; eE; close f NGC 55; f of 2."  As a result, Dreyer assigned it as IC 1537, though this section was sketched by both Dunlop and John Herschel (plate IV, #8).

 

The photographic appearance of the fainter eastern portion caused confusion.  In 1940, Harlow Shapley and J.S. Paraskevopoulo wrote NGC 55 was "possibly two overlapping systems, similarly inclined, with similar internal structure? The third interpretation, suggested in conversation by Dr. G.Z. Dimitroff, is lent color by the appearance of the object on small-scale long-exposure plates, where it appears to be a double, edge-on spiral, without nuclei and with the components differing perhaps three magnitudes in total brightness. Strong absorption may conceal nuclear regions; but a number of spirals that appear to be devoid of a central nucleus or strong central concentration are now known. It may well be that such objects will need to be recognized as forming a distinct class."

Lewis Swift found NGC 58 = Sw. 5-3 on 21 Oct 1886, in a trio with NGC 50 and NGC 54, with a 16" refractor at Warner Observatory.  There is nothing at Swift's position but his description reads "vF, pS, R, wide D * near sp; 3rd of 3." Herbert Howe, using the 20" refractor at Chamberlin Observatory, was unable to find NGC 58 on two nights and suggested that NGC 58 was a duplicate of NGC 47, discovered earlier by Wilhelm Tempel in 1886.  This requires that Swift's RA for NGC 58 was 1.1 minutes too large.  Despite Swift's comment "3rd of 3", his description of a "wide D[ouble] star nr sp" applies to NGC 47, making this equivalence very likely.  Dreyer repeats Howe's efforts in the IC II Notes and adds "probably = [NGC] 47".  See Corwin's notes for the full story.

24" (9/15/12): very faint, very small, round, 12"-15" diameter, just visible continuously. This galaxy is at the west end of the NGC 68 group and on a line extending northeast with PGC 1185, NGC 68 and NGC 70 with each galaxy separated from the next by less than 1'.  PGC 1185, misidentified in most catalogues as NGC 67 and the faintest galaxy in the central region, is situated just 44" NE.  PGC 1185 appeared extremely faint and small, 8" diameter.

 

18" (11/14/09): this galaxy and PGC 1185 were the faintest members viewed in the NGC 68 group.  NGC 67 appeared as a mag 16 threshold glow 1.7' SW of NGC 68.  It required averted to occasionally glimpse, though a few times I could tell it was elongated.  In a 22" scope, I was able to hold this galaxy continuously at over 400x.

 

PGC 1185 was occasionally glimpsed as a threshold "star" sandwiched between this galaxy and NGC 68 (0.8' from both galaxies).  Most sources identify PGC 1185 as NGC 67 and this galaxy as NGC 67A or anonymous although it was clearly shown on Rosse's sketch of the field.  The identification is corrected on the NGC/IC Project site.

William Herschel discovered NGC 68 = H. V-16 = h15 on 11 Sep 1784 (sweep 266) and recorded "extremely faint, 5 or 6' dia, 3 or 4 stars in it; but they seem to have connection with it."  This is the only galaxy credited to Herschel in the compact group, but he placed it in his fifth class of "large" nebulae, so doesn't apply to a single small galaxy.  Instead, Harold Corwin feels it's likely that Herschel saw the merged glow of NGC's 68, 70, and 71 (3 brightest in a small triangle in the core) and I agree, based on his size estimate.

 

John Herschel made a similar observation.  On 16 Sep 1828 (sweep 178) he wrote "An extr faint cluster with nebulosity, 5' diam.  Several *s 15...18m.  Seen distinctly, but there is also unresolved nebulosity.

NGC 90 = Arp 65 was classified as a Spiral galaxy with small, high surface-brightness companions on arms.  LEDA 1669552, the "companion" just beyond the northwest tidal extension (2.4' NW of NGC 90), appeared faint (V ~17.1), small, elongated 3:2 N-S, 10"x6".  A mag 15.7 star is 30" SE.

R.J. Mitchell, Lord Rosse's assistant, discovered NGC 90 and 93 on 26 Oct 1854. His description mentioned "Several S; F neb visible at once in finder" so John Herschel assumed at least 3 objects were discovered, which he catalogued as GC 40, 41, 42.  But a sketch of the NGC 90 field shows only two nebulae labeled as Alpha (now NGC 90) and Beta (now NGC 93).  Herman Schultz observed the field on 17 Oct 1866 with the 9.6" refractor at Uppsala and measured an object he thought was GC 40, but was actually Mitchell's Alpha.  His micrometric position matches UGC 208 = PGC 1405.  Stephan observed the pair (identified as GC 5097 and 5098) on 12 Oct 1869.  Because of an uncertainty in the position and identification, Dreyer catalogued this object in the GC Supplement (#5096) with the comment "Query = GC 40, 41, 42?". Dreyer equated GC 40 = 5096 in the NGC.

 

Modern catalogues misidentify UGC 208 as NGC 91 but Schultz's position for NGC 91 falls precisely on a very faint star 1.9' S.  This misidentification may have originated in Curtis' description of nebulae (1918) based on Crossley photographs at Lick observatory.  See Corwin's notes for further discussion.

NGC 93 was independently found by Heinrich d'Arrest on 5 Oct 1864 and catalogued by Dreyer as GC(S) 5098, as he was unsure of the positions and identifications.  Stephan observed NGC 90 and 93 (identified as GC 5097 and 5098) on 12 Oct 1869.  The two GC entries, #42 and #5098, were combined under NGC 93.

John Herschel discovered NGC 101 = h2321 on 25 Sep 1834 and logged as "pretty bright; pretty large; a little elongated; 45"; precedes a star of 14th magnitude."  On a later sweep he noted "very faint; round or very little elongated; gradually brighter in the middle; 15 arcseconds."  So the two observation differ significantly in terms of brightness.  His position matches ESO 350-014 = PGC 1518.

 

Pietro Baracchi observed this galaxy on 5 Oct 1885 with the Melbourne telescope and wrote "pF, pL, a little elongated following and preceding, about 70" long and 50" broad.  A star 14m following, a little north.  This object is not conspicuous - it is quite flat - or evenly lighted and the outline is not sharp."

24" (1/4/14): at 125x and 260x, ~40 stars mag 12-15 were resolved, mostly within or near a distinctive 3.3' string oriented SSW-NNE.  Two brighter mag 11.8/12.3 stars lie at the N end of the string, just detached from the richest clump of stars near the center of the cluster.  Another sparser string of stars is parallel and just 1' W of the main string. A string of stars oriented N-S is detached to the SE of the main string.  Observed with a 4 day moon up.

 

13.1" (10/20/84): 20 faint stars over unresolved haze, very elongated SSW-NNE.  Two mag 11 stars are at the north end.

 

John Herschel discovered NGC 103 = h20 on 5 Oct 1829 and recorded, "pS, p compressed cl; 3' diam; st 11...18m in 2 or 3 principal branches.  If this be VI 35 [NGC 136], there must be a mistake in my father's obs or mine of 6m in RA."  Herschel's conjecture was wrong - NGC 136 is a much smaller cluster, 6 minutes of RA east.

 

The first observation was made by William Herschel on 26 Nov 1788 (sweep 887).  He noted "clustering, small stars, considerable rich", but didn't assign it a discovery number.  He mentioned again, though, in his 1817 paper "Astronomical observations and experiments tending to investigate the local arrangement of the celestial bodies in space, and to determine the extent and conditions of the Milky Way."

V = 4.0;  Size 30.9';  Surf Br = 0.1

 

25" (10/26/22 - OzSky): viewed 47 Tuc at only 102x with a 48' field.  The astonishing cluster seemed to fill the vast majority of the field, down to the intensely luminous core, which was distinctly yellow-ochre colored.

 

30" (10/13/15 - OzSky): at 303x; the core was distinctly orange-yellow.  In addition, I immediately noted a couple of obvious orange supergiants at the south edge of the core and in the outer halo on the east side.

 

30" (11/4/10 - Coonabarabran, 163x and 264x): absolutely stunning view in the 30" at 163x and 264x.  Even in the 37' field of the 21mm Ethos, the stars appeared to fill the entire field, only thinning out near the edge.  The pinpoint stars were amazingly packed, but increased in intensity to a relatively small, blazing core, which was plastered with resolved stars.  The very center of the nucleus contained a small, intense knot overlaid with packed stars giving a strong impression of layers.  I immediately noticed the core had a pale yellowish tint.  

 

18" (7/10/05 - Magellan Observatory, Australia): at low power (76x using a 27mm Panoptic) the blazing core had an unusual, pale yellow hue.

 

20" (7/8/02 - Magellan Observatory, Australia): this was the best view I had of 47 Tucanae during the week.  At 212x, the entire 23' field was packed edge-to-edge with pinpoint stars and the blazing, intense core, which had a yellowish tint, was resolved into a mesmerizing dense mat of stars.  The halo extended to at least 30'.  

 

18" (7/6/02 - Magellan Observatory, Australia): at 171x, this breathtaking globular was viewed at over 50° elevation and was stunningly resolved into several thousand stars out to a diameter of over 25'.  The star density steadily increases towards the center.  The relatively small 4' core was blazing and highly resolved right to the edge of a very small compressed nucleus.  A 3-dimensional affect was very strong with layers of stars forming a dense mat over the core.  Many of the stars in the halo are connected in chains and lanes.  The 9 mm Nagler did a better job of busting apart the stars in the core, although the cluster overfilled the field at this power. Although the total visual magnitude is just slightly fainter than Omega Centauri and the size slightly smaller, 47 Tucanae is certainly equal if not surpassing Omega Centauri in visual impact due to its dazzling central blaze.

 

12.2" (6/29/02 - Bargo, Australia): While at Bargo, I observed 47 Tucanae for the first time. Though still very low in the sky the view was thrilling.  At 186x, the globular filled the 26' field with an uncountable number of stars. Strongly concentrated to an intense, blazing core which was only partially resolved at a low elevation.  The highly resolved outer halo extended ~25' in an irregular outline while the central halo was very symmetric.  This is the most prominent naked-eye GC as so much of its light is concentrated into the central core and it lies in a sparse field with no other rivals other than the SMC.

 

Naked-eye: easy 4th magnitude naked-eye blur just west of the SMC, seen many times from the southern hemisphere.  Visible in a dark sky while very low in the sky and from suburban locations when higher in the sky.

 

Nicolas-Louis de Lacaille discovered the nebulous appearance of NGC 104 = Lac I-1 = D 18 = 47 Tucanae = h2322 in 1751-1752 with a 1/2-inch telescope at 8x during his expedition to the Cape of Good Hope.  It appeared "like the nucleus of a fairly bright comet."  He placed it in group I, consisting of nebulae without stars.  The cluster was noted, though, as a "star" in Bayer's Uranometria, which was first published in 1603. The designation "47 Tuc" comes from Bode's extension of Flamsteed numbers to the southern constellations (these are not used today except for 47 Tuc and 30 Dor).

 

With his 9-inch speculum reflector, James Dunlop logged "(47 Toucan, Bode) this is a beautiful large round nebula, about 8' diameter, very gradually condensed to the centre. This beautiful globe of light is easily resolved into stars of a dusky colour.  The compression to the centre is very great, and the stars are considerably scattered south preceding and north following." His sketch (figure 1 in his catalogue) shows a beautifully resolved, elongated cluster.

 

John Herschel observed it for the first time on 11 Apr 1834 and logged "the great cluster preceding the Nubecula Minor. Estimated dia of the denser portion 5'; of the whole (not, however, including loose stragglers) 8'. Stars 14..16 mag. and one of 12th mag N.p. the centre. Excessively compressed. (N.B. In a sweep below the pole, when of course owing to the low altitude much of the light was lost.)"  His observation of 12 Aug 1834 reads: "A most glorious cluster. The stars are equal, 14th mag., immensely numerous and compressed. Its last outliers extend to a distance of 2 min, 16 sec in RA from the centre. It is compressed to a blaze of light at the centre, the diameter of the more compressed part being 30 arcsec in RA. It is at first very gradual, then pretty suddenly very much brighter in the middle. It is completely insulated. After it has passed, the ground of the sky is perfectly black throughout the whole breadth of the sweep. There is a double star 11th mag. preceding the centre (Pos. 226.5 - 6.5 arcsec in RA from centre of neb.)" On 21 Sep 1835 he wrote: "Fills the field with its stragglers, condensation in three distinct stages, first very gradually, next pretty suddenly, and finally very suddenly very much brighter in the middle up to a central blaze whose diameter in RA is 13.5 sec and whose colour is ruddy or orange-yellow, which contrasts evidently with the white light of the rest. The stars are all nearly equal (12..14 mag). A stupendous object."  His final record of the object was on 5 Nov 1836: "A most magnificent globular cluster. It fills the field with its outskirts, but within its more compressed part, I can insulate a tolerably defined circular space of 90" dia wherein the compression is much more decided and the stars seem to run together; and this part I think has a pale pinkish or rose-colour."  In his diary Herschel also refers to the "Rose coloured central mass".

Bindon Blood Stoney probably discovered NGC 126 on 4 Nov 1850.  Lord Rosse's 1861 publication mentions "3 others near [NGC 125 and 128]."  But no diagram was given and only two new objects - NGC 127 and 130 - were described in the 1880 publication.

 

Heinrich d'Arrest measured accurate positions on 19 and 21 Sep 1865 (published in 1867).  Édouard Stephan possibly observed it on 23 Aug 1871 as he noted 5 objects in the field (but no separate positions).  J.L.E. Dreyer, Lord Rosse's assistant, observed the field on 12 Dec 1874 and reported NGC 126 as "Suspected a nebulous knot between [NGC 125] and [NGC 128], a little south."  A sketch in the 1880 publication accurately places NGC 126.  Lord Rosse (1) and d'Arrest (2) were credited in the NGC.

Two mag 9.5/10 stars are at the N tips of these strings and the eastern string is richer and better defined.  Scattered mag 12-15 stars fill the interior of the wedge, with a couple of brighter stars on the south end, which is more eye-catching .

James Dunlop discovered NGC 134 = D 599 = D 590 = h2327 with his 9" reflector on 7 Jul 1826.  His description for D 599 reads "very faint nebula, about 25" diameter, rather elliptical.  North of Eta Caelae Sculptoris.  There are four small stars south of the nebula in the form of a lozenge."  His position is 22' NNW of the galaxy but the description of the four nearby stars to the south clinches the identification.  For D 590 he logged (handwritten notes), "a very faint round nebula, about 2' diameter, rather brighter in the middle, il defined.  South following Eta Sculptoris."

 

John Herschel's positio for h2327 is accurate and he noted it could be identical D 590.  His observation on 25 Sep 1834 reads, "vB; vL; vmE; pretty suddenly little brighter middle; 8' long; 1' broad; pos = 47.9°; dies away gradually at both extremities; has a star 10th mag., distance 45", pos = 327.9.  On a second sweep on 19 Oct 1835 he logged "bright; large; vmE; pretty suddenly little brighter middle; 4' long; 1' broad; position = 227°; the following of 2."  He also sketched the galaxy (Plate VI, figure 19), clearly showing its spindle-shape with tapering edges.

 

Joseph Turner sketched NGC 134 on 2 Nov 1875 with the 48" Melbourne Telescope (plate I, figure 1 of "Observations of the Southern Nebulae...") and noted, "The present appearance of nebula is exactly as represented in Herschel's sketch; the centre is sharp and stellar-like with power of 255; but with 420 it is more diffused, and somewhat sparkling. A careful examination leaves the impression that it is practically unchanged since Herschel's time, the only difference between his sketch and present aspect being the position of the North star, which in Herschel's sketch is shown in a straight line with the centre of nebula and s.f. star, whilst at present it is somewhat to the n.f. of that point; this may however be the fault of the engraver."

 

The earliest photograph is probably from 1909-1911 by Knox-Shaw at the Helwan Observatory with the 30-inch Reynolds reflector.  It was described as "B, 5' x 1', an elongated spiral."

24" (1/1/16): Hodge III is the brightest globular cluster in NGC 147 at V ≈ 16.5.  At 450x and 500x it only occasionally popped but was verified at the same position using a detailed finder chart.

 

I first identified two mag 13 stars at 1' separation oriented N-S, which are situated 5' SSE of the center of NGC 147.  These stars are just outside the halo of the galaxy.  A mag 14.7 star is 1' further NW, forming an obtuse isosceles triangle with the two mag 13 stars.  Hodge 3 is 41" N of the mag 14.7 star and nearly forms the 4th vertex of a parallelogram with these three stars.

 

John Herschel discovered NGC 147 = h29 on 8 Sep 1829 and recorded "very faint; very large; irregularly round; 4..5' diam; loses itself insensibly; has a *11m in the centre."  Bindon Stoney, Lord Rosse's assistant on 25 Oct 1851, logged "L, vF neby, round a * 12m.  I suspect it is a spiral of the faintest class, perhaps h 29."  Although William Herschel discovered NGC 185, his sweep pattern never included NGC 147.

 

On 21 Aug 1852, Birr Castle assistant George J. Stoney (returning after examinations at Trinity) wrote, "Involves some stars, one of about 12th or 13th magnitude, elongated; very faint."

 

In 1944 William Baade announced that NGC 147, along with NGC 185, were members of the Local Group (1944ApJ...100..147B) when they were resolved into stars on plates take with the 100-inch at Mt Wilson.  NGC 147 is considered a satellite system of M31 at a distance of 2.3 million light years.

Lewis Swift discovered NGC 150 = Sw. 6-3 on 20 Nov 1886 with his 16" refractor.  His position was 30 seconds of RA west of ESO 410-019 = PGC 2052.  Herbert Howe measured an accurate position in 1899-00 using the 20" refractor at Chamberlin Observatory (repeated in the IC 2 notes).  The error was also noted in the Harvard College Observatory NGC correction list published in 1906.

 

It was first photographed by Delisle Stewart at Harvard's Arequipa Station between 1898 and 1901 and described as a "Fine small spiral".  The galaxy was also photographed between 1909-11 by Harold Knox-Shaw at the Helwan Observatory and described as a "two-branched spiral".

48" (10/29/19): very bright striking spiral with an inner ring and a long, drawn out spiral arm!  Overall, at 610x the galaxy extended over 2:1 WSW-ESE, ~3.2' x 1.4'.  Very strongly concentrated with a very bright core that gradually increased to the center.  Immediately west of the core was a noticeably darker gap and a lower contrast gap was east of the core.  These gaps were outlined by bright arcs, each about 90°, creating a partial oval ring surrounding the core.

 

The western half of the halo had a low surface brightness and extended at least 1.5' from the center.  I noticed a brightening at the extreme west end of the halo.  Checking the SDSS, this is a split spiral arm, separated beyond a darker dust lane.  A thin, long spiral arm was attached at the south side of the core (along the inner ring) and was easily seen gently curving northeast, extending directly to a mag 12.6 star!

 

A small, faint knot, at most 10" diameter, was easily seen near the end of this arm, very close SSW [16"] of the mag 12.6 star.  This "knot" is a companion galaxy (2MASX J00340814-0941481), though its redshift is 1/3 greater than NGC 151, so it may be in the background.

 

24" (12/1/16): bright, fairly large, contains a very bright boxy rectangular central section that is slightly elongated NNW-SSE (this is the central bar and nucleus), encased by a fairly low surface brightness halo extended at least 2:1 E-W, ~2.7'x1.2'.  A mag 12.5 star is at or just off the ENE edge (1.7' from center). A superimposed companion is at the tip of the eastern spiral arm of the galaxy, very close southwest of the mag 12.5 star.  It was marginally glimpsed but only occasionally popped.

 

17.5" (9/17/88): moderately bright, moderately large, oval 5:3 WSW-ENE, 2.5'x1.5', bright nucleus.  A mag 13 star is at the ENE edge, 1.7' from the center.

 

13.1" (8/24/84): fairly bright, bright core, very bright nucleus, very faint halo elongated ~E-W.  A faint star is at the ENE edge.

 

William Herschel discovered NGC 151 = H. II-478 = h30 = h2330 on 28 Nov 1785 (sweep 479).  He logged "pretty bright, large, little extended, little brighter middle." On 10 Dec 1798 (sweep 1086) he noted "considerably bright, considerably large, brighter middle, nearly in the parallel, a little from south preceding to north following."

 

John Herschel observed this galaxy at Slough and at the Cape, where he recorded "pF; R; gradually brighter middle; 60" diameter."  His two entries were combined in GC 74 and his position matches MCG -02-02-054 = PGC 2035.  Lewis Swift found the galaxy again on 9 Aug 1886 and reported it as new in his 4th catalogue (#1) = NGC 153, though his RA was 17 seconds of too large.  So NGC 151 = NGC 153.

 

Based on photos taken at the Helwan Observatory in 1919-20 with the 30-inch Reynolds reflector, NGC 151 was described as "4' x 1.5', bright almost stellar nucleus; spiral with at least 3 long, much curved arms in what are almost stellar condensations.  One of the arms appears to wind completely around the nucleus, and possibly extend to more than 3' from it to a star in p.a. 190°."

William Herschel discovered NGC 157 = H.

Eduard Schönfeld, Heinrich d'Arrest and Father Secchi provided accurate positions, so the NGC position is correct.  Édouard Stephan observed the galaxy on 18 Sep 1873 (probably looking for H.

Lawrence Parsons discovered NGC 162 on 16 Oct 1866 using Lord Rosse's 72" and by Herman Schultz on 5 Sep 1867 with the 9.6" refractor at Uppsala Observatory. Both observers recorded a single star 75" NE of NGC 160.  This star was possibly noted even earlier by Heinrich d'Arrest on 22 Aug 1862.  Schultz assumed this object was GC 82, discovered by R.J. Mitchell at Birr Castle on 18 Sep 1857.  But Mitchell's object is a close companion of NGC 169 (now known as IC 1559), not NGC 162 as John Herschel assumed.  Dreyer also observed this star on 6 Nov 1874 and noted "An eS, F neb point, or probably a F* nf h79 in PA 78"."

 

In the GC Supplement, Dreyer incorrectly decided "Rosse nova does not exist [so GC 82 = IC 1559 did not receive an NGC number].  82 was undoubtedly observed instead of 79, which latter nebula is not double.  The description in PT 1861, agrees perfectly with the appearance of 82"  He added that "Schultz's GC 80 has not been seen in Birr before 1874: I have therefore entered it in the catalogue as a nova."  So, Dreyer assigned Schultz's GC 80 to the single star (the one first seen by Lawrence Parsons in 1866) following NGC 160 and renumbered it as GC 5107.  RNGC misidentifies NGC 162 with an anonymous galaxy close SE of NGC 160 and Dorothy Carlson incorrectly equates NGC 160 = NGC 162 in her NGC errata list.  Wolfgang Steinicke thoroughly covered the identifications of GC 80 and 82 in his book on the history of the NGC.

Heinrich d'Arrest discovered NGC 163 = Sw. 4-3 on 20 Sep 1865 with the 11-inch refractor at Copenhagen.  His mean position (also measured on the next night) matches MCG -02-02-066 = PGC 2149.  Although William Herschel's H. III-954 is equated with NGC 163, his observation more likely applies to NGC 165 (see that number).  d'Arrest noted the 32 second discrepancy between his RA for NGC 163 and that of H. III-953, but surprisingly d'Arrest didn't record NGC 165, so didn't make the connection between H. III-953 and NGC 165.

 

Lewis Swift independently found NGC 163 on 9 Aug 1886 and reported it in his 4th discovery list (#3).  Swift's RA was 14 seconds too large and falls between NGC 163 and 165 but Swift's positions for three other galaxies he observed on this night (NGC 153, 217 and 7774) are all 10 - 15 seconds of time too large.  This implies that Swift missed slightly fainter NGC 165. Based on a photograph taken with the Crossley reflector between 1912-13, Heber Curtis described NGC 163 as "Almost stellar; structureless; bright nucleus. A very faint spindle is 1.5' s.p.

William Herschel discovered NGC 165 = H. III-954 on 10 Dec 1798 (sweep 1086) and recorded "extremely faint, small."  His position is just 1.6' NNW of NGC 165 = PGC 2182, and much further from NGC 163 = PGC 2149, the galaxy associated with III-954 in the NGC.  In the 1912 revision of Herschel's catalogues, Dreyer noted the RA of H. III-954 was 28 seconds too large (for NGC 163).  Wolfgang Steinicke and Harold Corwin agree with the conclusion that H. III-954 more likely applies to NGC 165.

 

Wilhelm Tempel found NGC 165 in 1882 with an 11" refractor at the Arcetri Observatory and reported it as new in his fifth discovery paper.  He noted finding another fainter nebula 30 seconds following NGC 163.  Tempel's second nebula was assumed to be new, so he was credited with the discovery of NGC 165 in the NGC.  Spitaler measured an accurate position in 1891 at Vienna.

 

Based on a photograph taken with the Crossley reflector between 1912-13, Heber Curtis described NGC 165 as "Nearly round, 1' in diameter. A very faint, rather regular spiral. Nucleus almost stellar."

R.J. Mitchell, Lord Rosse's assistant, discovered NGC 169 on 18 Sep 1857.  His description reads, "a vS, double nebula, the north one is elongated south-preceding north-following, brighter middle."  A month later he logged "double nebula, alpha [on a diagram] is much extended preceding-following, bM.  Beta is lE nearly north-south, bM."  In Lord Rosse's 1861 publication, it was mistakenly assumed that the observation referred to NGC 160, so was not a new object.  The following year Heinrich d'Arrest independently discovered NGC 169 and was credited with discovery in the General Catalogue (GC 82), published in 1864.  Mitchell's "Beta" was assigned GC 80.

 

d'Arrest listed his discovery in a large table of new nebulae published in 1865, so he was able to add a footnote that his object was discovered earlier at Birr Castle (assuming it was identical to GC 80).  In the NGC, Dreyer correctly credited both LrR and d'Arrest for the discovery of NGC 169, but he mistakenly described NGC 160 as a double nebula (repeating Mitchell's error) and deleted GC 80 (Mitchell's "Beta").  Finally, the companion was catalogued as IC 1559, though it should have received a NGC designation.  See that number for more.  William Herschel recorded the nearby mag 6.2 star on 4 Dec 1784 (sweep 328), but missed the galaxy.  Immediately after logging the star he noted "a very thin whitish haziness all over", so sky conditions were poor.

 

MCG labeled the brighter northern galaxy as NGC 169B and the fainter southern galaxy (IC 1559) as NGC 169A.

R.J.

Ormond Stone made an independent discovery on 3 Nov 1885 with the 26" refractor at the Leander McCormick Observatory and recorded "F, S, mE 0°, bM, faint wing south-preceding."  His rough position (nearest min of RA) is 1.5 min of RA too far west but his description and sketch (examined by Harold Corwin) matches this galaxy. Stone was credited with the discovery in the NGC.  Finally, Stephane Javelle discovered NGC 178 again on 26 Aug 1892, assumed it was new based on position and listed it as the 28th object in his first discovery paper (J. 1-28, later IC 39).  Herbert Howe later searched for NGC 178 and measured an accurate position in 1898-99 (repeated in the IC 2 notes), though Dreyer failed to equate NGC 178 and IC 39.  See Corwin's notes.

24" (9/14/12): Hodge V is the brightest globular cluster in NGC 185, first identified by Paul Hodge in his 1974 paper "Photometry of the Globular Clusters of NGC 185" (PASP, 86, 289).  At 325x and 450x it appeared as an extremely faint star (V = 16.7), forming the southern vertex of a small equilateral triangle with a mag 14.5 star 20" N and a mag 15 star 20" NW.  This extragalactic globular was repeatedly glimpsed for brief moments and a couple of times it could be held for a few seconds.  Situated 3.8' NE of the center of NGC 185 and outside the visible halo of the galaxy.

 

17.5" (10/13/90): bright, very large, slightly elongated ~E-W, broad concentration but no nucleus. Three mag 14 stars are at the W, NW and SW ends.  Higher surface brightness than NGC 147.  The brightest globular is located 8' N of center and is a marginal object at high power (see description).  This is a satellite system of M31 and a Local Group member at a distance of 2.15 million light years.

 

8" (10/4/80): fairly faint, fairly large, diffuse, NGC 147 58' WNW.

 

William Herschel discovered NGC 185 = H. II-707 = h35 on 30 Nov 1787 (sweep 786). He recorded "pretty bright, very large, irregularly round, very gradually much brighter middle, resolvable, 5 or 6' diameter."

 

The first observation at Birr Castle on 28 Mar 1848 reads "Resolved by a power of 800, although the night was rather hazy." This is a good example of how preconceptions that nearly all nebulae were resolvable influenced the results. James Keeler first photographed the galaxy using the Crossley reflector at Lick before 1900.  It was described (1918 Curtis publication) as "rather irregular slightly oval, 3' long; there are two curious rifts near the nucleus; it appears to be an irregular spiral.  The nebular matter is faint and diffuse.  A star of mag 14 is north of the very faint nucleus."

 

In 1944 William Baade announced that NGC 185, along with NGC 147, were members of the Local Group (1944ApJ...100..147B) when they were resolved into stars on plates take with the 100-inch at Mt Wilson. In an unusual situation, Baade requested that an actual photographic print of NGC 185 was bound in his ApJ paper to demonstrate resolution, as detail was lost with an ordinary halftone illustration.

Bindon Blood Stoney discovered NGC 186 on 6 Dec 1850 (Friday).  Bindon may have been observing with his brother George Johnstone Stoney, who visited Birr Castle several weekends in Fall 1850. It was noted as "much smaller than alpha (NGC 194), and is suddenly brighter in the middle and I think a nova."  Heinrich d'Arrest made an independent discovery on 23 Sep 1862 with the 11" refractor at Copenhagen.  d'Arrest measured an accurate position.  Édouard Stephan made another observation on 29 Oct 1875, while working through the galaxy group.

48" (10/25/11): HCG 5A is the brighter northern component of a double system forming NGC 190.  It appeared bright, moderately large, slightly elongated E-W, 50"x40", bright core, stellar nucleus.  Forms a very close double with smaller and fainter HCG 5B just 21" between centers.  The halos of the two galaxies are in contact.  HCG 5C is 0.8' NNE and HCG 5D is 0.9' S.  The entire length of the N-S chain of four galaxies is 1.6'.

 

18" (8/26/06): this double system was just resolved into two very close, small knots, roughly 20" each in diameter with their halos in contact.  Both components have faint stellar nuclei.  The northern component (HCG 5A) was slightly brighter and larger.  HCG 5C is a difficult object 1' NW.  The entire quartet is arranged in a N-S chain with a total length of only 1.6'.

 

18" (11/23/05): NGC 190 is a double system which often appears as an elongated glow, 40"x20", oriented N-S.  With careful viewing, the system just resolves into two very small round knots, just 20" between centers.  The northern component is ~20" diameter and the southern member ~15". The two knots both have faint stellar nuclei and appear virtually tangent.  A third member, HCG 5C, is occasionally visible as an extremely faint knot off the NW side.

 

17.5" (12/11/99): Initially seen as a single faint, elongated glow at 220x.  At 280x in moments of good seeing this object cleanly resolved into two very close, very small knots with the brighter component on the north side.  HCG 5C was only intermittently visible with averted vision as a 15" threshold knot.

 

17.5" (9/5/99): NGC 190 is a challenging double system best viewed at high power.  Using 280x, at first appeared as an elongated irregular glow but with extended viewing, two "knots" oriented N-S were resolved within a common halo.  The brighter and larger component (HCG 5A) is at the north end and appears very faint, very small, round, 20" diameter.  The southern component (HCG 5B) is extremely faint and small, perhaps 15" diameter.  HCG 5C is a threshold knot 1' NW.  The HCG is a subgroup of AGC 76 whose core is ~20' SSE and includes IC 1565, 1566 and 1568.

 

17.5" (10/8/88): very close double system, faint, small, elongated SSW-NNE, irregular.  HCG 5B is a very small companion attached at the south edge just 22" between centers.  In a compact group of four (HCG 5).

 

Lewis Swift discovered NGC 190 = Sw. 5-8 on 22 Oct 1886 with the 16" refractor at Warner Observatory.  His position is just 6 sec of RA east of UGC 397.  His description mentions "3 or 4 stars near sp".  There are two mag 13 and 14.7 stars about 2' SW, but perhaps he also noticed the companion at the south edge (HCG 5B) and took it to be stellar.  Herbert Howe, observing with the 20" refractor in Denver, noted a mag 12.5 star lies about 30" due south of the nebula.  But this probably refers to HCG 5B.  MCG identifies M+01-02-042 as NGC 190 instead of both -041 and -042.

William Herschel discovered NGC 193 = H.

Only 25 seconds later, Herschel logged a second object: "very faint, very small, but I have not been out long enough, any may be a deception."  His offset from NGC 193 clearly matches NGC 204, though likely due to his uncertainty it wasn't catalogued.

 

William's RA for NGC 193 was off, so his son John thought his own observation (recorded as h37) was new: "very faint; large; close to a *15.  RA by III. 595, which this precedes 25.5 seconds."  Birr Castle assistant R.J.

Ralph Copeland, assistant for Lord Rosse (Lawrence Parsons), discovered NGC 203 on 19 Dec 1873.  It was found while observing the field of NGC 193 and 204.  His micrometric position matches CGCG 383-061.  Édouard Stephan also discovered this galaxy on 29 Oct 1875 (rough position 3' to the WNW) and reported it as new (list 8, #2) based on a position taken 18 Nov 1876. But Stephan misidentified his offset star so his position for NGC 211 was 20' too far east.  Applying his offsets to the correct stars lands NGC 211 on NGC 203, with discovery priority going to Copeland.

William Herschel made the first observation of NGC 204 = h42 on 21 Dec 1786 (sweep 657).  Just 25 seconds after discovering H. III. 595 (later NGC 193), he logged "very faint, very small, but I have not been out long enough [he had just started observing that night], any may be a deception."  His offset from NGC 193 clearly matches NGC 204, but it wasn't catalogued and Herschel was uncredited in the GC and NGC.

 

John Herschel made an independent discovery on 16 Oct 1827: "pretty bright; round; the following of 2 [with NGC193]."  His position (marked as uncertain) is between NGC 193 and 204.  In the Slough Catalogue, he mistakenly equated h42 with his father's III. 595, which applies to NGC 193.

13.1": bright, very large, elongated 5:2 NNW-SSE, 10'x4', quite prominent but only a gentle broad concentration.  G73, the brightest globular cluster in M110 (or associated with M31), lies 6' E of center and appears as a 15th magnitude "star".

 

8" (10/4/80): fairly bright, large, elongated ~N-S, companion to M31.

 

Charles Messier discovered M110 = NGC 205 = H. V-18 = h44 on 10 Aug 1773 and made a sketch showing M31 and its two companions, though he didn't mention it in his three catalogues. He first published a description in 1798 and the sketch was published in 1807. Kenneth Glynn Jones suggested adding NGC 205 as M110 in a 1967 Sky & Telescope article.

 

Caroline Herschel independently discovered M110 on 27 Aug 1783 with her 4.2-inch comet-seeker reflector.  She entered it as #9 in her discovery log and described "about 1/2° preceding and a little north of Mess. 31, a nebula, there are many stars besides in the field, but these two are rather largest."  William observed M110 on 24 Oct 1783, just before starting his sweeps.  Observing with his 18.7", he first observed H. V-18 (later NGC 205) in his 18.7" on sweep 282 (5 Oct 1784), when he was observing off the meridian to the east.  On 17 Oct 1786 (sweep 613), he called it "vB, mE, above 20' long nearly in the meridian; a few degrees from np to sf, the branches lose themselves." Again a week later on 24 Oct 1786 (sweep 621), he logged "eB, mE.  I suppose not less than 1/2° long and 10 or 12' broad.; very gradually much brighter middle; so as to come to a luminous nucleus.  The time very inaccurate, the telescope being off the roller, and only guided by hand."  William wrote In his 1785 Philosophical Transactions paper, "there is a very considerable, broad, pretty faint, small nebula near it; my sister discovered it, August 27th, 1783, with a Newtonian two-feet sweeper. It is not the 32d of the Connoissance des Temps.."  Caroline was credited with the discovery in the NGC.

 

M110 was observed with Lord Rosse's 72" on 2 Nov 1850 and "spirality" was suspected (falsely).  A later observation on 16 Oct 1855 recorded "vL; mE np by sf; sharp nucleus, for some distance round which, the neb. is bright and then suddenly decreases; there is a bright star np the nucleus; and another involved in sf end; another in preceding border.”

Size 4.2'x2';  PA = 0°

 

24" (8/25/19): quite prominent, very large elongated patch, extending 4'x2' N-S.  A number of faint stars were easily seen superimposed.  A brighter, narrow "spine" stands out well with the general star cloud.  NGC 206 can be traced further SSW, where it merges with Association 79, a very large 6'x2' cloud of lower surface brightness oriented SSW-NNE.  Association 80 is a 3' patch directly south of NGC 206 by 7' and has 3 brighter stars superimposed on the north side.  This patch also includes C107, a 5" open cluster on its south side.

 

48" (11/1/13): Using Jimi Lowrey’s 48-inch f/4, we carefully examined the large association NGC 206 for resolved stars using the finder chart in Stephen Odewahn's 1987 study "A photometric survey of the rich OB association NGC 206 in M31”.  I assumed using a labeled photographic chart it would not be difficult to identify individual stars, but his chart failed to capture the range in visual brightness of the Milky Way and cluster stars.  As a result I had to carefully verify small patterns of stars (triangle, quadrilaterals, etc.) several times to feel confident of the identifications.  After several minutes of observation, I had identified the 6 or 7 brightest members down to V = 17.6, as well as the superimposed Milky Way stars.  The brightest “star" (Odewahn #12 at V = 16.1) at the north edge was relatively prominent, but most were in the mag 17-17.5 range.

 

Finally, I stopped carefully scrutinizing individual stars, relaxed my eyes and just gazed at the entire star cloud with averted vision.  I was startled that in moments of good seeing, roughly 20 additional extremely faint stars popped in and out of view, mimicking the appearance of a dense open cluster or partially resolved globular cluster!  Based on photometry in the paper, the magnitudes of the resolved stars extended down to approximately V = 18.3-18.4. The cloud, itself, was quite irregular and split up into several slightly brighter patches.

 

Checking journal articles afterwards, I found that Odewahn #12 (= BH05) was not a single star but was listed as a globular cluster candidate (M31GC J004030+404530) in Barmby & Huchra’s 2001 paper "M31 Globular Clusters in the HST Archive: I. Cluster Detection and Completeness”.  But the 2010 paper "A Photometric catalog of 77 newly-recognized star clusters in M31” by Paul Hodge described the results of an HST WFPC2 search for star clusters in active star-formation regions of M31.  BH05 was reclassified as a luminous and massive young cluster with an unusually elliptical shape.  In addition, Odewahn’s #40 and #112 (and perhaps others) are also clumps of stars or clusters, but visually were essentially stellar.

 

17.5" (8/18/93): fairly faint, fairly large, elongated 5:2 N-S, 4.0'x1.6', low and uneven surface brightness.  A few very faint stars are just visible over surface including a brighter star at the south tip.  Located 40' SW of the core of M31.  This is the huge star cloud at the SW end of M31.

 

8" (12/6/80): very faint, moderately large, elongated N-S, low surface brightness patch near the SW end of M31.

 

William Herschel discovered NGC 206 = H. V-36 = h45 on 17 Oct 1786 (sweep 613). He recorded "very faint, very large, much elongated, about 20' long nearly in the meridian [N-S], or a little from np to sf."  His orientation is accurate, but the size estimate was much too large!  Caroline assumed it was a new discovery but according to Wolfgang Steinicke, William's first observation was made on 5 Oct 1784 (sweep 282), while observing off the meridian to the east.  He logged "a streak of milky nebulosity, horizontal, or part of the 31st Nebula."  An accurate position couldn't be determined in this orientation.  John Herschel simply called it "a very large space filled with neb.”

 

E.E. Barnard independently discovered NGC 206 in 1883 and assumed it was new.  On 14 Sep 1885 he reported [AN 2687], "about two years ago, I found with my 5-inch refractor, a moderate size nebula involved with the extreme preceding end of the Great Nebula in Andromeda.  I have now confirmed the observation with the 6-inch Cooke Equatorial and as I can find no record of such nebula I suppose it is new."  Barnard quickly caught his mistake and credited Herschel the next month [AN 2691].  Interestingly, Barnard also reported discovery of the M31 association A54 on the opposite end of M31, though for some reason Dreyer didn’t assign this object a NGC designation.

J.L.E. Dreyer discovered NGC 207 on 29 Oct 1877 as the observer on Lord Rosse's 72".  He wrote, "About 35 seconds preceding and 25' ± south [of NGC 210] is [NGC 178], very faint, S, lE p f, much brighter middle to a nucleus, stellar, 5' nnf a coarse double star 10-11 and 12m.  A very insignificant object."  The description applies, as well as the time difference (actual value 32 seconds preceding) in RA although the galaxy is 5' NNW of the coarse double star instead of NNE as stated.

 

Dreyer assumed R.J. Mitchell's description from 7 Dec 1857 referred to NGC 207, but as it mentions the object is elongated N-S, it more likely applies to NGC 178.  Ormond Stone independently discovered NGC 207 at Leader-McCormick Observatory on 3 Nov 1885 and reported it as new (LM 1-9) in the observatory's first discovery list.

 

IC 41 (discovered by Javelle) lies 3.7' north, although MCG, PGC and HyperLeda incorrectly equate IC 41 with NGC 207 (error also in Megastar).  RNGC misclassified NGC 207 as nonexistent and it was reported as not found at Helwan observatory in 1924 (though.  MCG -03-02-035 was noted 4' S of IC 41).  See RNGC Corrections #5.

Édouard Stephan discovered NGC 211 = St. 8a-2 on 29 Oct 1875 (rough position 3' to the WNW).  He reported it as new (list 8, #2) based on a position taken 18 Nov 1876, but there is nothing (other than a faint star) near his position.  Corwin found that Stephan misidentified his offset star (GSC 0014-1250 at 00 40 43.5 +03 28 05) so his position for NGC 211 was 20' E of NGC 203.  When his offsets are reapplied they point directly to NGC 203, discovered three years earlier by Ralph Copeland.  So, NGC 211 = NGC 203, with the original discovery going to Ralph Copeland.  Emmanuel Esmiol did not catch Stephan's error when his rereduced Stephan's positions at the Observatoire de Marseille, so the position is incorrect in his 1916 paper.

He recorded "faint, pretty large, little elongated, little brighter middle."  John Herschel observed NGC 217 on 14 Dec 1830 (sweep 310) and noted "not vF; S; gradually brighter in the middle; 10-15"."  Lewis Swift found this galaxy again on 9 Aug 1886 and reported it as new in his 4th discovery list (#4).  His position was 15 seconds of RA too large, a similar offset as other objects he observed that night.

 

In his comprehensive book on William Herschel observations, Wolfgang Steinicke mentions that Herschel made an early observation ("nebula north preceding 17 Ceti") on 24 Dec 1783 (sweep 62), but didn't catalogue the observation, probably due to an insufficient position.

24" (12/22/14): at 260x: moderately bright and large, irregularly round, ~0.8' diameter though the halo increases in size and shape with averted vision.  A brighter nucleus is offset to the east side of the galaxy, so could be mistaken for a knot in the halo.  Forms an interacting pair (VV 527) with CGCG 519-022 1.4' ENE.

 

CGCG 519-022 was fairly faint, fairly small, slightly elongated N-S, 0.4'x0.2', very weak concentration.  The SDSS reveals numerous thin, blue arm segments of NGC 218 that are apparently tidally stretched towards CGCG 519-022.

 

17.5" (9/1/02): fairly faint, fairly small, irregular shape and surface brightness, 1.0' diameter, broadly concentrated.  Forms the right angle of a small isosceles triangle with two mag 13.5-14 stars 1.4' N and 1.3' W.  Forms an interacting pair with MCG +06-02-017 1.4' E.  The companion is very faint, small, elongated 2:1 N-S, 0.5'x0.25'.  Member of the Pisces-Perseus Supercluster.

 

Édouard Stephan discovered NGC 218 = St. 8a-3 on 19 Oct 1873 and logged an initial position only 30" E of center of UGC 480.  But there is nothing at his published position (measured on 17 Oct 1876), which is 40" S of mag 8.9 SAO 54096 (Delta RA = 0).  The only nearby candidate is UGC 440, about 9' WNW of this position, and this galaxy is taken as NGC 218 in all modern catalogues.

 

I checked Emmanuel Esmiol's 1916 re-reduction of Stephan's positions at Marseilles Observatory and found that NGC 218 was left off of the main tables, but replaced with an "Anonymous" galaxy using a delta RA of +4 min from the same offset star.  This offset corresponds exactly with UGC 480.  At the bottom of the page Esmiol added the note "wrongly identified as NGC 218."  So, clearly NGC 218 = UGC 480.  Harold Corwin and Wolfgang Steinicke agree with this analysis.  Wolfgang notes in his book on the history of the NGC, that Esmiol's catalogue gives 4 discoveries of Stephan that did not receive NGC designations, but he missed this connection with NGC 218.  This identification has now been incorporated into NED, although it is still incorrect in HyperLeda (as of 2013) as well as the NGC/IC Project, which has not been updated in a long time.

18" (7/10/05 - Magellan Observatory, Australia): at 228x, this SMC cluster appeared moderately bright, fairly small, round, ~50" diameter, brighter nucleus.  There was no resolution except for a single faint star near the center.  A mag 11 star lies 1' NE and just south of NGC 222.  NGC 220 is the first of three in a chain with NGC 222 1.5' NE and NGC 231 4.0' NE.  Also NGC 176 lies 24' NW.  NGC 220 is located at the west edge of a large SMC star cloud (Hodge Association 3).

 

James Dunlop discovered NGC 220 = D 2 = h2338 on 1 Aug 1826.  He described (single observation) a "faint ill-defined nebula, about 1 1/2' long, irregular figure, rather branched.  This is just involved in pretty strong margin [edge] of the Cloud."  His position is 3.6' NW of NGC 220 and the comment "rather branched" suggests he may have seen both NGC 220 and 222 as a single elongated object.  Herschel assigned D 2 to NGC 231 = h2340 (also in the chain), but it has a lower surface brightness and less likely to have been noticed.

 

John Herschel observed NGC 220, along with NGC 231, on 12 Aug 1834 (sweep 482) and recorded "F, very gradually brighter middle, irregular figure."  In Sep 1835 (sweep 625) he wrote "The first of an irregular string of nebulae and stars which descends at an angle of about 45 degrees from the centre to the edge of the field (i.e. in a north-following direction)."   Harold Corwin notes that h2339 (later NGC 222) may be a 4th observations of this cluster (see notes).

 

Pietro Baracchi observed the cluster on 16 Dec 1887 (first of 14 objects) with the Melbourne telescope and called it "pB, irr, pS, little brighter middle, amidst stars."

Guillaume Le Gentil discovered M32 = NGC 221 = h51 on 29 Oct 1749.  He reported "While observing the Andromeda Nebula with a fine 18-foot telescope ... I saw another small nebula, about one minute in diameter which appeared to throw out two small rays; one to the right and the other to the left."  Messier found it independently in 1757 while observing M31, unaware of Le Gentil's earlier observation.

 

William Herschel first observed M32 with his 18.5" on 5 Oct 1784 (sweep 282), while observing off the meridian to the east. The position could not be determined accurately, but it was catalogued as I-54. A correction was made later when Caroline realized it referred to M32.  A late observation was made on 26 Dec 1813: "A very bright, round nebula, very gradually brighter to the middle up to a nucleus."  John Herschel recorded (1 Oct 1828), "eB; pL; suddenly brighter in the middle to a * 10m; 40"; a small star follows it 11.5 seconds."

18" (7/10/05 - Magellan Observatory, Australia): second and the smallest of three SMC clusters in a string with NGC 220 1.5' SW and NGC 231 2.5' NE.  At 228x, it appeared as a fairly faint, small, round glow of ~30" diameter, unresolved.  A mag 11.5 star lies 30" south.

 

John Herschel discovered NGC 222 = h2339 on 11 Apr 1834 and simply recorded "vF, R, outlying."  His position, though, is unusually poor - landing 3.7' S of NGC 220.  Since h2339 was only recorded on the single sweep 441, Harold Corwin suggests this number may be another observation of NGC 220, which was recorded on 3 later sweeps, but not the one on 11 Apr 1834!  As NGC 220 is much more prominent than the smaller cluster taken as NGC 222, it seems unreasonable that Herschel would have missed NGC 220.  On sweep 625, Herschel recorded NGC 220 as "The first of an irregular string of nebulae and stars which descends at an angle of about 45 degrees from the centre to the edge of the field (i.e. in a north-following direction)".  It's very possible that the cluster taken as NGC 222 was one of these "string of nebulae and stars" as it is just 1.5' NE of NGC 220, so perhaps he did see the cluster on this date.  See Corwin's notes for more on this identification.

 

James Dunlop's D 2, discovered on 1 Aug 1826, probably refers to this chain.  He described a "faint nebula, about 1 1/2' long, irregular figure, rather branched.  This is involved in the margin of the Nebula minor."  His position is ~3.5' WNW of NGC 220/222 and may apply to NGC 220 (brightest cluster) only.  Herschel assigned D 2 to NGC 231 = h2340, which is likely incorrect due its low surface brightness.

 

Pietro Baracchi observed the cluster on 16 Dec 1887 (second of 14 objects) with the Melbourne telescope and called it "pB, roundish, pS little brighter middle, amidst stars."

George Phillips Bond discovered NGC 223 = HN 7 = Au 4 = Sw. 6-5 on 5 Jan 1853.  It was found with the 15-inch Merz refractor during the Harvard Zone observations of stars near the celestial equator.  He noted a round nebula, between stars #131 and 132 and measured the dec, but not the RA.  The discovery was listed as #4 in Auwers 1862 list of new nebulae, though the RA was only given to the nearest minute of time.  Heinrich d'Arrest independently discovered the galaxy on 1 Jan 1862 and assumed it was a new discovery.  He added a note of Bond's earlier discovery in his 1865 catalogue of new nebulae.  Lewis Swift made another discovery (list VI, #5) on 21 Nov 1886.  Finally Swift "discovered" it again on 12 Nov 1890, and described Sw. 10-1 (later IC 44) as "eF; S; R; bet 2 st." His position was ~2' too far north and Dreyer either assumed it was new or just missed the equivalence.  In any case, NGC 223 = IC 44.

17.5" (7/5/86): the remarkable "Andromeda galaxy" is very bright, extremely large, very elongated 4:1 SW-NE, about 2.5° length.  Very large bright core containing a stellar nucleus using direct vision.  There are two black parallel dust lanes along the NW side of the core.  The galaxy extends beyond the star cloud NGC 206 located about 40' SW of the core.

8" (number observations starting in 1980): amazing at 50x with a prominent dust lane along NW side, stellar nucleus.

 

Persian astronomer Abd-al-Rahman Al-Sûfi first mentioned M31 = NGC 224 = h51 in his "Book of Fixed Stars" (964 AD) as the "Little Cloud" lying before the mouth of a Big Fish (an Arabic constellation).  Surprisingly, Tycho Brahe didn't mention M31 in his star catalogue (nor Hipparchus or Bayer), which included 6 nebulous objects (only real one was M44). German astronomer Simon Marius made the first telescopic observation of M31 (actually of any nebula) on 15 Dec 1612 and it appears to be composed of rays of light, increasing in brightness towards the center, marred by a dull, pale light.  It appearance "resembling the light of a burning candle, atsome distance, shining through translucent horn."  Giovanni Hodierna listed it as a new nebula in his catalog based on his observation in 1654, apparently unaware of Marius'earlier observation.  Cassini, in 1740, represented its shape as nearly triangular.  Le Gentil considered it round for some years, then oval, but always of a uniform light.  In 1764 Messier wrote "it resembles two cones or pyramides of light, opposed at their bases, the axes of which are in direction NW-SE."  Due to these varying descriptions, it was thought the nebula might be variable.

 

William Herschel first observed M31 with his 6.2" reflector on 6 Aug 1780 ("has no star in it").  But using the same scope on 2 Aug 1783 he noted, "227x, a strong suspicion of stars.  This speculum has not light enough.  I doubt not but 20 feet will confirm it.  460x, suspicion still stronger."  He was obviously mistaken on the resolvability.  Herschel also noted the nebula "begins to shew a faint red colour."  Perhaps he detected a slight hue to the nuclear region (red giants), though this seems unlikely and he described many globular clusters, as well as double stars, as having a faint red color.  In 1826 John Herschel wrote, "At present it has not, indeed, a star, or any well-defined disk in its center, but the brightness, which increases by a regular gradation from the circumference, suddenly acquires a great accession, so as to off the appearance of a nipple as it were in the midd, of very small diameter (10" or 12")...Its nebulosity is of the most perfectly milky absolutely irresolvable kind, with the slightest tendency to that separation into flocculi above described in the nebula in Orion..."

 

The quasi-stellar nucleus was observed by Johann Lamont on 13 Oct 1836 with a 10.5-inch refractor at Munich Observatory and measured as 6.9" diameter.  George Bond made a remarkable sketch in 1847 using the new 15-inch Harvard refractor, showing two sharply defined dust lanes, a stellar nucleus and M32 and M110 embedded within the halo of M31. He mentioned "a sudden interruption of light, appearing like a narrow, dark band, in which the eye could detect no deviation from perfect straightness, streating, in the direction of the axis of the nebula, entirely across the field of view; exterior to this, with respect to the axis, was another band or canal..."  Bond also traced the major axis to a length of 4°.  Leopold Trouvelot produced a beautiful sketch of the dust lanes in 1874 at the Harvard College Observatory.

 

The spiral nature, though, was first revealed in photographs by Isaac Roberts in 1888 with a 20-inch reflector (reproduced in many publications) and E.E. Barnard in 1890 with the 12-inch refractor, though neither used in the word "spiral" in their papers.  Roberts speculated wildly on the nature of M31, suggesting it was a "new solar system in the process of condensation from a nebula" and the two companions, M32 and M110, were "already undergoing their transformations into planets."

 

Ernst Hartwig discovered the first extragalactic supernova near the center of M31 on 20 Aug 1885 with the Dorpat Observatory's 9.6" Fraunhofer refractor.  SN 1885A = S And reached mag 5.85 and faded to mag 14 a half a year later.  The brightness (if a nova) seemed evidence that M31 was relatively nearby (within the Milky Way).  In 1899, though, German astronomer Julius Scheiner obtained a spectrum using a 7.5 hour exposure and found "No traces of bright nebular lines are present, so that the interstellar speace in the Andromeda nebula, just as in our stellar system, is not appreciably occupied by gaseous matter." He further stated "previous suspicion that the spiral nebulae are star clusters is now raised to a certainty, the thought suggests itself of comparing ..our stellar system, with especial reference to its great similarity to the Andromeda nebula."  This added strong support for the "island-universe" theory.

 

In 1919 Knut Lundmark obtained a distance of 650,000 light years based on the brightness of M31 novae, implying an extragalactic nebula. But in the early 1920's Adriaan van Maanen claimed he measured internal displacements on photographs taken 12 years apart that showed rotation or motion outward along the spiral arms, implying a close distance and small diameter. The Island Universe question was effectively ended when Hubble identified a Cepheid variable (V1) in M31 on a plate taken October 5-6, 1923 and derived a distance of 930,000 l.y based on the Period-Luminosity relation.  In 1929 he obtained a distance of 900,000 l.y. based on a large number of Cepheids.

 

In 1943-44, while the Los Angeles area was in a World War II blackout, William Baade first resolved the central region of M31, M32, M110 as well as NGC 147 and NGC 185 using the 100-inch at Mount Wilson.  He  identified two distinct populations of stars based on their metallicity, naming young, high-velocity stars in the disk as Type I and older red stars in the bulge as Type II. The differences in Population I and II Cepheids modified the P-L relation and increased the distance by 2.5x.

Caroline Herschel discovered NGC 225 = H.

William Herschel first observed the cluster on 12 Mar 1784 before he began sweep 165 and called it "a cluster of coarsely scattered large stars, seeming to contain many smaller...7 ft [6.2"] power 57. 20 large stars. Carolina found it Sept. 27, 1783."   On 26 Nov 1788 (sweep 887 with his 18.7"), he recorded "a good many coarsely scattered L stars of an equal size, they take up a space of 15 or 20'."

His position falls very close to the cluster taken as NGC 231 (ESO 029-005 = Lindsay 25), but Corwin suggests NGC 231 really refers to the entire string of 3 clusters - NGC 220, 222 and 231.  I agree - this was his first observation here and he certainly wouldn't have picked up just the single faintest cluster but either noticed the entire string or just NGC 220 and 222, the two brightest clusters.

 

Herschel suggested h2340 might be equivalent to D 2, but Dunlop likely saw only NGC 220 or both NGC 220 and 221, which he described as "a faint nebula, about 1.5' long, irregular figure, rather branched. This is involved in the margin of the Nubecula Minor."

 

Pietro Baracchi observed the cluster of 16 Dec 1887 (third of 14 objects) with the 48" Melbourne telescope and called it "eeeF, very small thin nebulosity around a minute star. Two or more stars near."

John Herschel discovered NGC 241 = h2342 on 12 Aug 1834 and described "a very F, R nebula or group (We are now fairly in the Nubecula Minor, and field begins to be full of faint perfectly irresolvable nebulous light."  There is nothing at his sinngle Cape of Good Hope position but 10' N is h2343 (later NGC 242).  Herschel caught this error and corrected the NPD in an errata list at the end of the CGH catalogue, though apparently he didn't notice the nearly identical positions.  Since Herschel only observed NGC 241 on a sweep where NGC 242 was not recorded, Harold Corwin (as well as ESO and Eric Lindsay) equate NGC 241= NGC 242.  Since NGC 242 refers to his first observation it should be the primary designation.  See Harold Corwin's notes for more.

18" (7/10/05 - Magellan Observatory, Australia): at 282x, this SMC cluster appeared fairly bright, slightly elongated E-W, 0.8'x0.6'.  A faint star is at the west end and another faint star or clump of stars is at the SE end.  A pair of mag 12.5/13 stars lies 2.5' SW.  NGC 248 lies 9' NE and NGC 256 can be found 11' ESE.

 

John Herschel discovered NGC 242 = h2343 on 11 Apr 1834 and recorded "pL; vF; R; very gradually brighter middle; (in a sweep below the pole and ill seen) the RA is probably also in error.  On a second sweep he recorded "a binuclear nebula, or two, vS, R, running together."  Finally on a third sweep he noted "a small irresolvable knot in the bright part of the Nubecula Minor."  NGC 241 = h2343, recorded in Aug 1834, is a duplicate observation (see notes).

 

Interestingly, Pietro Baracchi observed the cluster on 16 Dec 1887 (as well as numerous other SMC clusters) with the 48" Melbourne telescope and logged it as two objects (labeled as "D" and "E") "almost forming a double nebula".  The main NW clump was called "pB, very small, nebulous star" and the SE knot as "pB; eeS; nebulous star very close to D.  I believe two minute stars in D and one in E which makes the objects sparke, many stars in the field."  This matches Herschel's description of "a binuclear nebula, or two..."  SIMBAD labels the NW clump as NGC 241 = Kron 22w = Lindsay 29w and the SE clump as NGC 242 = Kron 22E = Lindsay 29e and NGC 241/242 is listed as a star cluster pair in 2000A&AS..146...57D.

48" (10/23/14): At 488x with an NPB filter the view of the Skull Nebula was breathtaking and all the structure in a detailed photograph was visible.  The thin brighter rim varied in brightness, thickness and scalloped structure along its entire length.

 

The rim is brightest along a 60° arc on the western side, bulging inward just north of center, creating a small darker indentation in the rim due west of the prominent central star. Moving counterclockwise around the rim, a small brighter, elongated patch is at the northwest edge, close to a mag 11.5 star just outside the planetary.  The rim is relatively weak along the north side, but two brighter (detached) patches are along the northeast side.  An irregular, elongated luminous patch spreads inward here.  This glow is fairly prominent just northeast of center, on line with the central star and the second interior mag 12 star (southwest of center). A second luminous patch is midway from the central star to the north rim.  The rim is weakest overall along a 90° arc on the eastern side, near a mag 13.5 star, which is embedded just within the planetary. Two more luminous patches are visible at the south rim, with the westernmost glow both larger and brighter.

 

The interior is relatively dark, though glows weakly with subtle variations, creating pockets of darkness - one is northeast of the central star - and mild enhancements.  A small diaphanous glow is just south of the mag 12 star on the southwest side.  More extensive milky nebulosity extends inward from the southern rim, though the most prominent interior glow is the split nebulosity mentioned earlier on the northwest side.

 

33" (9/15/07): gorgeous annular planetary viewed at 200x.  The thin brighter rim was striking and varied in brightness and thickness around the periphery.  The rim is brightest along the western or WNW edge and weakest on the east side.  The interior was darker but irregular in surface brightness.

 

18" (10/13/07): 175x gave an excellent view using the NPB filter and the thin, bright irregular rim (only dimming on the east side) and darker center was quite striking.

 

18" (8/23/03): I took a quick look at 160x from Chew's Ridge with a thin waning crescent low in the ENE.  Without a filter I don't remember the brighter rim being so crisply defined and the annularity so clear.  The superimposed stars gave the planetary a transparent, 3-dimensional feel as if I was seeing inside the object. 

 

17.5" (1/8/00): at 100x, appears as a moderately bright, 3.5' irregular glow with a darker center and encompassing four stars including the 12th magnitude central star.  Excellent contrast gain using an OIII filter, which sharpens up the edge of the roundish annulus and enhances the irregular surface brightness.  The halo is brightest along a 270° arc running from SW to NE and is clearly weakest at the east edge of the halo.  A mag 11.5 star is embedded at the NW edge of the halo 2.0' from center.  The irregular central hole is much darker but faintly luminous.  A mag 12 star is also superimposed southwest of the central star and a 4th star is just inside the eastern boundary.  The central star forms a thin right triangle with the other two brighter stars.  At 220x, the western 90° outer arc is brightest and there appears to be a knot embedded at the NE edge of the halo.

 

17.5" (9/19/87): fairly bright, large, 4' diameter, annular.  Four stars are involved including the central star.  This planetary has an irregular surface brightness with subtle structure.

 

13.1" (many dates from 11/13/82 to  8/24/84): fairly bright with filter, clearly annular, sharper edges.  NGC 255 lies 15' SSE.

 

8" (11/5/83): fairly faint, large, four stars involved.  No annularity noted.

 

16x80 (8/24/84): faintly visible in finder.

 

80mm finder (10/13/07): visible unfiltered at 25x.  Nice contrast gain using the NPB filter and the planetary also appears to increase in size.

 

William Herschel discovered NGC 246 = H. V-25 = h56 on 27 Nov 1785 (sweep 478).  He recorded "four or five pretty large stars forming a trapezium of 4 or 5' diameter. The enclosed space is filled up with milky nebulosity faintly terminated. The stars seem to have no connection with the nebulosity."  Immediately afterwards he swept up the galaxy NGC 255, which is 25' NNE.

 

Isaac Roberts described NGC 246 as a spiral nebula based on an early photograph.  In 1912 Knox-Shaw reported it was not a spiral, but "like the Owl nebula", based on a photograph taken at the Helwan Observatory with the Reynolds reflector from 1909-11.  Still Hardcastle later classified NGC 246 as a spiral nebula.  Campbell (at Lick) and Paddock found the spectrum to be of a PN.  Based on a Crossley photograph, Heber Curtis described (1918) "a somewhat irregular oval, brightest on western edge; 4'x3.5' in PA 120°.  Periphery clear-cut, with a broken ring effect.  Very faint, irregular matter in inner parts.  The central star is bluish, and considerably brighter photographically than visually."

 

The 1973 "Revised New General Catalogue of Nonstellar Objects" (RNGC) reversed the sign of the declination (+), and this typo was copied into some amateur software and digital setting circles.

48" (10/31/13): at 287x, NGC 247 spanned at least 18'x5' NNW-SSE and stretched from an HII region at the NNW tip to beyond the mag 9.5 star (HD 4529) near the SSE end.  A very large, elongated darker region (though not primarily caused by dust extinction), dubbed the "Needle's Eye", forms an interesting feature on the NNW side of the halo.  Visually it extended at least 3.5'x1.0'.  A relatively bright HII knot (identified in NED as MRSS 540-038059 from the "Muenster Red Sky Survey") is beyond this feature at the NNW end of the major axis, 9.5' from center.  This knot appeared fairly faint, relatively large for an HII region, elongated ~N-S, 20"x12".  A second well-defined HII knot is MRSS 540-038506, found 5' NNW of center.  This easy patch appeared fairly faint, elongated, 15"x10".  At least two small knots (including MRSS 540-038001) are on the SW side of the halo, ~2.4' from center and ~1.5' E of a mag 12-12.5 star just off the west edge of the disc.  Finally, I picked up a faint, very small knot, ~6" diameter, situated 3.5' SSE of center and 1.1' N of a mag 13.5 star.  This HII region (not in the MRSS) forms a "double" with a mag 15 star 15" N.

 

17.5" (11/1/86): bright, very large, bright core, elongated 7:2 N-S, 14'x4'.  The southern extension is brighter and mag 9 SAO 166572 is superimposed at the southern end about 6' from the core.  Burbidge's Chain (VV 518) lies 18' NNE.

8" (10/4/80): very large, elongated ~N-S, bright core.  A mag 10 star is at the south tip.  The southern extension appears brighter.

 

William Herschel discovered NGC 247 = H. V-20 = h57 on 20 Oct 1784 (sweep 303) and logged "a Streak of light about 27' long, and in the brightest part, which was pretty bright is 3' or 4' broad. The extension nearly in the meridian (I believe a little from from S.p. to N.f.) ... The situation is so low, that it would probably appear of much greater extent in a higher altitude."  His size estimate (27') was much too large but it was probably a difficult observation, with the large galaxy at an elevation of 16°.   John Herschel also  observed NGC 247 at Slough on 16 Sep 1830 (sweep 293) and noted "extremely faint; very large; very much elongated; very gradually little brighter middle; 10' long; pos 172.0 deg. Has no bright star in it, but a star 8.9 mag at some distance n.p."  Surprisingly, he made no (published) observations at the Cape of Good Hope.

 

Based on a photograph taken with the Crossley reflector, Heber Curtis described NGC 247 as "a faint, very large spiral, 18'x5' in p.a. 175°.  Nucleus stellar; many almost stellar condensations.  Whorls somewhat irregular, and indistinct." (1918)

18" (7/10/05 - Magellan Observatory, Australia): at 228x this fairly faint SMC nebulous cluster appeared as an irregular glow, 0.8'x0.6', elongated NW-SE.  There was a good response using a UHC filter at 76x.  One or two stars or knots are involved including a small nebulous knot at the southeast end (N13A).  NGC 256 lies 8' SSE and NGC 242 is 9' SW.

 

John Herschel discovered NGC 248 = h2344 on 11 Apr 1834 and logged "very faint.  Below the pole, and the sweep otherwise irregular."  On a later sweep he recorded "faint, elongated or binuclear, small, very gradually a little brighter in the middle."  His position matches the knot at the southeast end.

 

Pietro Baracchi observed this cluster on 16 Dec 1887 along with a number of other SMC clusters with the 48" Melbourne telescope.  He listed NGC 248 as two separate objects; the NW object (SMC-N13B) was labeled as "F" and called "pF; eeS a faint nebulous star" and the SE object was labeled as "G" (SMC-N13A) and described as "very close to F, almost forms a double nebula - this is a little brighter and larger than F.  pB; vS; R; pmbM."

A few individual stars were superimposed.  The view with a NPB was superb as the contrast was increased as well as the size to over 2'.  NGC 249 resides in a gorgeous region of the SMC with a bright background due to the star density.  This nebula contains one of only 12 known Wolf-Rayet stars (SMC AB 10) in the SMC.

 

18" (7/10/05 - Magellan Observatory, Australia): at 228x this SMC cluster with nebulosity appeared fairly bright, fairly large, slightly elongated, 1.3'x0.9', weakly concentrated. Two or three faint stars are involved including a mag 13 star just north of the center. The UHC filter produces a good contrast boost and increased the size to at least 2'.  Forms a pair with NGC 261 4.5' ESE with NGC 242 18' S.

 

James Dunlop discovered NGC 249 = D 19 = h2346 on 5 Sep 1826 with his homemade 9" speculum reflector. He recorded "a small faint elliptical nebula - this is the preceding in a line of small faint nebulae."  His position is just 3.7' N of this SMC nebula.

 

John Herschel recorded NGC 249 on 3 sweeps.  In Sep 1835 (sweep 635), he remarked "faint, large, round; very gradually brighter in the middle; 2' across. Here begins a starry region of the Nubecula Minor."  On 4 Oct 1836 (sweep 738), he wrote, "pretty bright, pretty large, oval, resolvable, 2' diameter."  Herschel noted that Dunlop's D 19 or 21 might be equivaent.

V = 7.2;  Size 27.5'x6.8';  Surf Br = 12.7;  PA = 52°

 

48" (10/23/14): although I've viewed NGC 253 several previous times with Lowrey's 48", I'm always amazed by the spectacular view as the mottled galaxy explodes into numerous bright knots, dusty patches, dark lanes and luminous star associations.  Using a 21mm Ethos (232x), NGC 253 completely filled the 26' field.  The central region of this starburst galaxy contains a blazing, nonstellar nucleus surrounding by an intense, elongated core with several bright patches around the periphery of the core (segments of the inner spiral arms).  Just northwest and southeast of the nucleus are extremely bright sections of the core.  Since the galaxy is only 12° from edge-on, many visible features extend parallel to the SW-NE major axis (PA = 52°).

 

A dark lane running SW-NE parallels the core just off its northern side.  Close northwest and parallel to this dust lane is a very bright, fairly narrow arm, extending ~3' in length.  Another thin arm (also running SW-NE) is to the southeast of the core with a prominent, very thin section ~3.5' SW of center, just southwest of a superimposed mag 12.5-13 star.  Three smaller bright patches surround a superimposed star ~2.5' NE of the nucleus.  The brightest and largest of these patches is close southeast of the star.  Further northeast the surface brightness lowers in the outer portion of the galaxy, but it still appears curdled and blotchy.  Several bright stars are near the periphery including a mag 9.3 star 6.2' SW of center and a mag 11.6 star 3.8' W of center.  A brighter patch is ~3.5' WSW of center is near the latter star.  Additional luminous patches are further out on the southwest end.

 

30" (10/12/15 - OzSky): superb view at 152x and 303x with NGC 253 within 10° of the zenith.  Much of the detail seen in Lowrey's 48" was visible, although the bright patches were not quite as contrasty.  The nucleus is a very small region embedded in a very bright, elongated central region that is enhanced immediately south of the nucleus.  A thin, luminous "arm" extends in the direction of the major axis near the north side.  A long spiral "arm" is along the northeast flank of the galaxy, extending 5 or 6' in length.  Three slightly brighter patches were noted to the northeast of the core close to a superimposed star (also marked in the 48" observation).  A bright, elongated strip was along the southwest side, about 2.8' NNW of a mag 9.3 star near the southwest edge (6.2' from center).

 

30" (11/5/10 - Coonabarabran, 264x): stunning view in the 13mm Ethos at 264x although the galaxy overfilled the 23' field.  The dust structure and knots were mesmerizing but I didn't take detailed notes.

 

17.5" (many dates 8/2/86 to 8/29/92): at 100x; very bright, very large, edge-on 6:1 SW-NE, 30'x5', at 100x.  The galaxy exhibits only a weak central concentration to a small elongated core that is slightly larger than the visible knots.  Remarkable dust structure and mottling visible particularly on the southwest extension and a dark lane runs along the north side.  Three faint HII knots are visible near a superimposed star on the southwest side and a slightly brighter knot lies northeast of a star near the core.

 

13.1" (9/11/82): very bright, elongated 4:1 SW-NE, very mottled, dust lanes, dark patches, 30' diameter.

 

8" (10/4/80 and 9/11/82): very bright, large and elongated!  Mottled appearance, 25'-30' diameter.

 

10x30mm IS binoculars: easily visible as an elongated glow.

 

Caroline Herschel discovered NGC 253 = H. V-1 = h61 = h2345 on 23 Sep 1783 from Datchet with her "small Newtonian Sweeper of 27 inches focal length [4.2" aperture], and a power of 30."  She entered it as #10 in her discovery log and NGC 253 was the only galaxy she discovered.  William then observed it in his 6.2" reflector and described it using 57x as a "nebulous spot lengthened out to a considerable extend from south preceding to north following ..."

 

William found it again just a month later (30 Oct 1783) while just starting to sweep horizontally with his new 18.7-inch (solo object in sweep 8).  Initially he thought it was new, but after looking for his sister's nebula unsuccessfully, he realized it was the same object.  He wrote, "On looking at the nebula a long while the suspicion of its consisting of stars grows stronger as it begins to put on a faintly mottled appearance."  On 27 Oct 1785 (sweep 467) he recorded "about 45' long and 7 or 8' br; cB, mBM.  The place taken is that of the brightest part of it, where there is a small star visible, which however I suppose has no connection with the nebula.  It makes an angle of 25 or 40° with the meridian, from sp to nf.  The faint ends of it require much attention to be seen, and I believe extend much farther than I could trace them."

 

John Herschel recorded it from the Cape as "vvB; vvL; vmE; 30' long, 3' or 4' broad; has several stars in it; gradually much brighter middle to a centre elongated like the nebula itself. The nebula is somewhat streaky and knotty in its constitution and may perhaps be resolvable." A second observation in 1836 was logged as "vvB; vvvL; a superb object; 24' in length, breadth about 3'; pos = 143.8 very exact. Its light is somewhat streaky, but I see no stars in it but 4 large and one very small one, and these seem not to belong to it, there being many near."  In the GC, he noted the position angle should read 54.5°.  John Dunlop didn't publish an observation from Paramatta (near Sydney) as it lies a couple of degrees outside his northern declination cut off.

 

William Lassell sketched NGC 253 from Malta in November 1863 with his 48".  His sketch included numerous dark lanes and rifts on the southwest side and a very irregular outline. Wilhelm Tempel's sketch with the 11" Amici refractor at Florence captures several small knots (brightest in the nucleus) and accurately depicts the surrounding star field and superimposed stars.  The origin of the "Silver Coin" nickname goes back to at least 1964 (Time-Life International edition of "The Universe"), with the description "Silvery Coin of the flat Sc spiral NGC 253", though the 1962 edition published in the U.S. reads "Silvery Dollar ..."

John Herschel made a single observation, "vF; L; R; gradually brighter in the middle; 30"."  In 1912 Harold Knox-Shaw identified this galaxy as an "spiral with many stellar condensations in the whorls", based on photographs taken with the 30" Reynolds reflector at the Helwan Observatory between 1909-11.

John Herschel discovered NGC 256 = h2348 in the SMC on 11 Apr 1834 and described "not vF, S, R, has a star 9th mag Nf."  On a second sweep he logged "F, S, R, gradually brighter in the middle, 40" south of a star 8th mag. (In Nubecula Minor)."  His third observation reads "F, lE, 30", precedes a star 9th mag" and a fourth record states "F, S, R, 18"; a star 9th mag Nf."

 

Pietro Baracchi observed this cluster on 16 Dec 1887, along with a number of other SMC clusters, with the 48" Melbourne telescope.  He described NGC 256 (labeled as "H" as "follows G [NGC 248] by 30s and is 7' 20" south of it.  pB, very small, sparkling, stars are in it - resolvable?  Probably a group of close stars, only few - immersed in very faint nebulosity."

Stoney probably also discovered NGC 260 to the northeast (the 3rd nebulae), and it was also seen in 1854, though d'Arrest was credited with the discovery in the NGC.

George Johnstone Stoney discovered NGC 260 on 22 Dec 1848 with LdR's 72" and recorded "3 neb in a line nff, p one = h59 [NGC 252], other two vF [NGC 258 and NGC 260], middle one [NGC 258] eF, vS, distance of extremes about 12'."  Although NGC 260 = UGC 497 is 9' ESE of NGC 252, it is collinear with the other two, and most likely the 3rd nebula seen by Stoney.  Another observation in 1854 also mentions "3 neb".

 

Heinrich d'Arrest independently discovered NGC 260 on 27 Aug 1865 with the 11" refractor at Copenhagen.  His position matches UGC 497.  He noted it was "one of Rosse's" although d'Arrest, instead of LdR, was credited with the discovery by Dreyer.  Édouard Stephan also made an observation on 28 Oct 1877, after observing NGC 252, though he was likely already aware of NGC 260.

SMC-N19 lies 5' ESE.  At 244x it was a fairly faint, very large nebulous glow, ~3' diameter.   With careful viewing an uncatalogued detached piece is sometimes visible to the NW (centered at 00 47.5 -73 05) and very faint nebulosity spreads to the southwest for a total diameter of 4' diameter.  Unfiltered a 6' cloud of at least 50 mag 12.5-15 stars (Hodge Association 12) are involved with the nebula.

 

SMC-N30 lies ~11' ESE.  At 244x unfiltered it was a fairly easy, fairly large, irregular curving or kidney-shaped nebula SW-NE, ~1.5'x0.8'. Unfiltered a couple of 14th magnitude stars are involved. Adding a NPB filter, the nebulosity was prominent and filled in to a more roundish outline.

 

18" (7/10/05 - Magellan Observatory, Australia): at 228x this SMC HII region appeared fairly bright, moderately large, round, 1.5' diameter with a single mag 13 star at the center (emission-line star Lin 78 = SK 9).  A UHC filter produced a good contrast gain and increased the size to over 2'.  A group of four stars follows including supergiant SK 13 (three brighter in a string and one faint star) and a number of faint stars are scattered nearby.  Forms a similar pair with NGC 249 4.5' WNW.  NGC 267 lies 12' SE.

 

James Dunlop discovered NGC 261= h2349 = D 4 = D 21 on 1 Aug 1826.  He described "a considerable condensation of the nebulous matter of an irregular figure in the margin of the bright part of the cloud, 2' or 3' diameter.  His position is about 7' too far ENE, though the description probably applies to both NGC 249 and 261 and perhaps N19.  His published description for D 4, though, is "faint round nebula, about 30" diameter."   D 21 was logged on a drift on 5 Sep after recording D 19 = NGC 249, and described as a "small round faint nebula." His position was 3' too far N (same offset as NGC 249).

 

John Herschel made 3 observations, first logging it in Sep 1835 (sweep 625) as "very faint, round, gradually brighter in the middle, 2' across, resolvable."  On 4 Oct 1836 (sweep 738), he described it as "pretty bright, round, 60". Has a star 13th mag in centre. Occurs in a field illuminated by the Nubecular Minor and many stars."  Herschel noted this object could be either Dunlop 3, 4 or 21.

SMC-N25 is a separate 1' patch 2' NNE that appeared fairly bright (with the filter), moderately large, round glow, ~50" diameter.  SMC-N28 is a very large, lower surface brightness patch (barely detached from NGC 267), ~1.5' diameter, centered ~2.3' ENE of NGC 267.  On close inspection it was divided into two sections on the north and south side and weaker in the center.  The southern section (SMC-N28A) was extended E-W and slightly brighter.

 

18" (7/10/05 - Magellan Observatory, Australia): at 228x this SMC cluster with nebulosity appears as a fairly faint, fairly large irregular glow ~2'x1.4'.  The surface was grainy with a half-dozen mag 14 stars resolved (Hodge Association 15).  There was a good response using a UHC filter, which increased the size of the visible nebulosity.  Collinear with two mag 10.5 stars ~6' SE.  A string of brighter stars to the north heads east for 17' towards NGC 290.  LHa 115-N25, a very small detached piece ~2' N, appears as a 15" glow and increases the total size to nearly 5'.

 

John Herschel discovered NGC 267 = h2352 in the SMC on 4 Oct 1836 and recorded "a faint, pretty large, cluster of very small stars. It is the preceding knot (or centre of condensation) of the resolvable portion of the Nubecula Minor which fills the subsequent field and consists of irregularly scattered clustered stars 12...20th mag."  His position is on the southwest side of the cluster/nebula.

Size 35'x30'

 

18" (2/16/07): remarkable view of this detailed emission nebula/cluster at 115x and 220x.  Without a filter at 220x about three dozen stars are visible in the region of the nebula, including a number of faint stars.  At the center of the cluster (IC 1590) and nebula (NGC 281) is the multiple star HD 5005 = Burnham 1, a striking triple with a difficult 4th component at 1.1".  A 13" pair of mag 11.5 stars lie 0.9' SW of Burnham 1.

 

The nebulosity responds dramatically to a UHC or OIII filter.  The two brightest regions have a butterfly appearance with the two lobes or wings partially divided by a curving dust lane oriented roughly N-S. A fainter detached portion is on the southeast side.  The overall dimensions extend to 15'-18'.  The two lobes are fairly similar in size and surface brightness, though the following section is larger including the southern piece.  The western section has the brightest and most sharply defined edge running along its southern border and oriented E-W.  A long straight dust lane extends along the southern boundary of both lobes and defines the sharp edge on the western lobe.  The curving central dust lane intrudes into the nebula on the south side and nearly divides the two sections, though weak nebulosity connects the two wings.

 

17.5" (9/28/02): the bright central quadruple (ADS 719 = Burnham 1) includes a mag 8.6/9.1/9.8 trio at 4" and 9".  At 140x, a fainter companion (mag 10) at 1.54" separation was just visible close following the brightest member and is cleanly resolved at 324x.

 

17.5" (10/17/98): spectacular view of this detailed HII region at 100x using an OIII filter.  This 15' nebulous complex has a mushroom appearance and is separated into three main lobes apparently by dust.  The brightest and largest lobe is following a bright triple star embedded near the center (8.6/9.2/9.8 at 4" and 9").  There appears to be a much fainter detached piece off the south end of this lobe.  Preceding the triple star is a section that is noticeably elongated and irregular in surface brightness fading to the NW.  The section to the north is faintest and separated from the eastern lobe by a curving dark lane.  A dark intrusion, apparently due to obscuring dust, is visible south of the triple star.

 

13.1" (8/24/84): very large, fascinating nebulosity, very irregular, dark gaps between sections, five brighter stars mag 8.6-12.5 involved.  The brightest star is a very close double.

 

80mm (2/16/07): at 13x and a UHC filter, the PacMan nebula is easily visible surrounding the central star.

 

E.E. Barnard discovered NGC 281 visually on 26 Nov 1881 (Sidereal Messenger, Vol 2, p226 and AN 369, 108, 1884) with his 5-inch refractor at Nashville and recorded a "large, faint nebula, very diffuse, not less than 10' diameter."  IC 11, found around 1892 by Barnard using the 6-inch Cooke refractor at Vanderbilt Observatory in Nashville (probably relayed directly to Dreyer) was placed 30 min of RA west, but Corwin notes that the description "vF, L, triple * on np corner" points to NGC 281 and perhaps he made a transcription error.  IC 1590, discovered by Bigourdan on 31 Oct 1899 is a large, scattered cluster on the west side.  NGC 281 is misclassified as an open cluster in the RNGC, as Barnard made no reference to a cluster.

30" (10/15/15 - OzSky): this very loose globular appeared fully resolved at 303x.  There were too many stars to possibly count, but certainly several hundred were resolved including a number of relatively bright stars (brightest members mag 12.6).  The core was loosely overlaid with a dozen or so brighter stars.  A number of stars in the halo appeared to be arranged in strings and arcs including one string extending towards the west.

 

18" (1/1/08): at 220x-280x, ~60 stars were resolved in an 8' diameter.  This globular has a very loose, irregular appearance with a very small brighter core containing a clump of resolved stars.  A string of stars running SSW-NNE runs through the west side of the halo with a brighter star (double) at the NNE end of this string.  A roughly parallel string also passes through the east side of the halo.  Located 1.8° SE of NGC 253 and form a nice pair in the 80mm finder at 13x.

 

18" (8/25/06): this bright globular is quite loose (concentration class 10) and well-resolved at 220x over the entire face and halo.  The outer halo is very irregular with a scraggly appearance and extends to 8'-10' in diameter.  Roughly 100 stars were resolved in total.

 

18" (8/23/03): bright but loose globular, well-resolved at 323x into 75-100 stars (difficult to count).  A number of the stars are clearly aligned in long chains.

 

17.5" (8/29/92): very bright, very large, round, ~8' diameter.  Well-resolved over entire disc into 75-100 stars mag 13-15 over background glow although not densely packed.  Observation made from the White Mountains (12,500 ft).  In a previous observation, roughly 60 stars were resolved, only weakly concentrated in core.

 

13.1" (9/11/82 and 11/5/83): 30-40 stars resolved over haze.

 

8" (10/31/81): faint stars resolved across entire disc at 200x with averted, many near visual limit

 

8" (10/4/80): very large, grainy, few stars resolved at the NW and south edges, other clumps on the verge of resolution.

 

15x50 (8/25/06): easily visible in IS binoculars as a fairly large, diffuse glow.

 

8x50 (11/5/82): fairly easy at just 8x.

 

William Herschel discovered NGC 288 = H. VI-20 = h74 = h2354 on 27 Oct 1785 (sweep 467).  He described it as "pretty bright, large, oval round, brighter in the middle, 7 or 8' long, 4 or 5' br."  His summary description (including a 2nd observation) reads "cB, irregularly round, 8 or 9' diameter, a great many of the stars visible, so that there can remain no doubt but that it is a cluster of vS stars."  Caroline Herschel missed this cluster two years earlier when she discovered NGC 253.

 

John Herschel observed this globular both at Slough and at the Cape.  From the southern hemisphere is called it a "globular cluster; bright; large; round; gradually brighter in the middle; all resolved into stars 12..16 mag; 5' diameter."

 

NGC 288 has a galactic latitude of -89.4°, so it is within 37' of the south galactic pole.

25" (10/17/17 - OzSky): at 244x; bright, fairly small, irregular, triangular shaped, 40" diameter.  A star or quasi-stellar knot is at the north tip.  SMC-N45, located 4.5' SE, appeared bright, moderately large, irregular or triangular in shape, 35"-40" diameter.  Several very faint stars are superimposed or at the edges of the glow including a couple of mag 15 stars at the south edge and a couple of mag 15.5 stars at the east edge.  Two mag 13/14 stars lie 0.8' SE.

 

18" (7/10/05 - Magellan Observatory, Australia): fairly faint, very small, granular, 20" diameter, brighter core.  A faint star or knot is at the north edge (may be a compact HII region).  A pair of mag 10/11 stars 8' NE are collinear with the cluster.

 

LHA 115-N45 (cluster with nebulosity) lies 4.5' SE.  This SMC HII region and cluster appeared as a faint, elongated patch with a few faint stars resolved around the edges.

 

John Herschel discovered NGC 290 = h2357 in the SMC on 11 Apr 1834 and simply logged "eF".  His position (single sweep) is about 35" N of the cluster. 

 

Glen Cozens associates Dunlop's D 5, discovered on 5 Sep 1826, with NGC 290.  Dunlop's rather generic description "a faint ill-defined nebula about 12" diameter" and poor match in position (12' to the SE), makes this identification rather arbitrary.  In fact, his position for D 5 is 5' due north of NGC 294, which seems a more logical assignment.

Naked-eye (6/29/02 - Bargo): this number refers to the entire SMC.  My first view of the SMC was outside Sydney with Les Dalrymple.  I only took observing notes (through a 12.2") on SMC globular NGC 121 and nearby cluster Kron 3, as well as 47 Tucanae.

 

Amerigo Vespucci was the first northern hemisphere explorer to see the SMC in 1501, 20 years earlier than Magellan.  This was mentioned in a 1990 article by Dekker.

 

John Herschel (h2356) has two entries: "I should consider this to be about the main body of the Nubecula Minor, which is here fairly resolved into excessively minute stars, which are however certainly seen with the left eye."  On a later sweep he noted: "Hereabouts seems to be placed the main body of the Nubecula Minor which is a Faint, Rich, Large Cluster of very small stars (12..18) filling many fields, and broken up into many knots, groups, and straggling branches. But the whole is clearly resolved into stars."

 

Pietro Baracchi observed the region between NGC 220 and NGC 294 over 16 and 17 Dec 1887 using the 48" Melbourne telescope.  Along with discovering a few new objects that went uncredited (Bruck 67 near NGC 294, Kron 25, SMC-N45), he wrote "About this region there is a very large cluster of stars scattered in an irregular way - from 12 to 18.  This covers more than one field ..with the supposed [GC 166 = NGC 294], there are other small groups surrounded by extremely faint nebulosity; and along this space occupied by the objects from A [NGC 220] to N [NGC 294] there are several stars which seem to be nebulous.  All the region along with these objects the sky is almost continuously covered with a multitude of stars, which render the observations difficult and confusing."

James Dunlop discovered NGC 294 = D 5 or D 6 = h2358 on 5 Sep 1826.  He described D 5 as "a small faint nebula, about 10" or 12" diameter." and D 6 as "a faint nebula, about 20" diameter".   D 5 was placed 5' too far N, while D 6 (logged next on the drift) is 5' too far SSE.  Either could apply.

 

John Herschel first observed this nebula on 11 Apr 1834 (sweep 441).  He simply noted "eF.  In a sweep below the Pole." and added a note later "This obs give 47 -- instead of 46 -- for the min of RA.  The earlier minute preferred."  In Sep 1835 (sweep 625) he recorded the RA minute as 46, which was used in the GC and NGC but this is 1.0 min too far west.  He referenced D 5 as the discovery.

 

Pietro Baracchi observed this cluster on 16 and 17 Dec 1887, along with a number of other SMC clusters with the 48" Melbourne telescope.  He described NGC 294 (labeled as "N") as "pB, pL, R, gradually brighter in the middle.  N follows M [Bruck 67, which he discovered] by 18 seconds and is 2' north of it."

24" (10/1/16): at 375x; faint, small, slightly elongated, 15"-18" diameter, very weak concentration.  Located 6.5' SW of mag 7.8 HD 5801.

 

NGC 295 is the slightly fainter of a pair with CGCG 501-058 4.8' ENE.  The companion appeared fairly faint, small, slightly elongated, 20" diameter, increases to a small bright nucleus and stellar peak, overall fairly high surface brightness.  CGCG 501-058 is situated just 2' SW of mag 7.8 HD 5801 and it helped to place the bright star off the edge of the field.

 

Ralph Copeland discovered NGC 295, along with CGCG 501-058, on 26 Oct 1872.  While observing the field he assumed was NGC 296, he found two nebulae and wrote, "(GC) 167 [NGC 296] F, R, *10m (yellow) Pos 29.6 deg, Dist 123.1".  Nova [NGC 295], S, R, and with a * or another neb 10" n. Pos from [NGC 296] 242.0 deg, Dist 314.6" or 21.6 seconds p[receding], 147.6" s[outh]."  Dreyer used William Herschel's (inaccurate) position for NGC 296 to compute a position for the "nova" GC 5123 (future NGC 296) in the GC Supplement and NGC.

 

There is nothing at Copeland's offset from NGC 296.  A 10th magnitude star is near NGC 296 but it's not at the reported position angle and separation, so it's clear Copeland misidentified the field and Corwin considered NGC 295 as lost.  Confusing the situation further, the computed position for NGC 295 happens to land on NGC 296!  As a result, all modern catalogues label NGC 296 as NGC 295 and UGC 562 is misidentified as NGC 296.

 

Recently (2016) Yann Pothier was able to identify the correct field about 1° ENE, surrounding mag 7.8 HD 5801 = SAO 54330.  This star is 115" distant in PA 32° from CGCG 501-058, so Copeland assumed this galaxy was NGC 296.  The second object is CGCG 501-056, located 288" in PA 248° (southwest) from CGCG 501-058.  Although Copeland discovered both galaxies, NGC 295 applies to CGCG 501-056 and CGCG 501-058 is left without an NGC designation.

William Herschel discovered NGC 296 = H. II-214 on 12 Sep 1784 (sweep 268).  His description reads, "F, E, preceding a bright star.  Appears almost like a brush issuing from the star, but does not join it by a good deal."  Although his RA was 20 seconds too large and his declination 1' too far N, it's clear from his description that NGC 296 = UGC 562.

 

Dreyer used Herschel's (poor) position to derive the position of NGC 295, a much fainter galaxy found by Ralph Copeland.  See NGC 295 for the story.  Coincidentally, Dreyer's erroneous position for NGC 295 happens to land on Herschel's II-214!  As a result UGC, CGCG, PGC and RNGC misidentify NGC 296 as NGC 295.  In addition, RNGC misidentifies UGC 565 as NGC 296.

Albert Marth discovered NGC 297 = m 19 on 27 Sep 1864 with Lassell's 48" on Malta and simply noted "eF".  His position is 2 sec of RA west and 1' S of much brighter m 20 = NGC 298, discovered at the same time.  It's possible that Marth confused a close, faint double situated 2' S of NGC 298 as a nebula.  But 1.3' SW of NGC 298 at 00 54 58.9 -07 20 59 (2000) is a nearly stellar galaxy, described here, which is a more likely candidate.  In any case, NGC 297 is not identical to NGC 298 as stated in the RNGC.  See Corwin's notes.

25" (10/17/17 - OzSky): at 244x; bright, fairly small, round, high surface brightness, 0.8' diameter. Contains an intensely bright quasi-stellar nucleus.  A few stars were resolved at the edges at 397x.  Brightest in a group of clusters with NGC 306 5' SE, Kron 30 3.7' W, Lindsay 51 8.5' NE, and Kron 28 14' NW.

 

Lindsay 51 appeared moderately bright, fairly small, irregular shape, ~30" diameter, very small bright nucleus. Situated just 0.6' W of a mag 10.6 star (SMC yellow supergiant) in a rich section of the SMC.

 

Kron 28 appeared fairly faint, moderately large, round, ~45" diameter, low surface brightness glow extending to the west of mag 10.7 HD 5148 = V Tucanae (mag 10-12 eclipsing binary superimposed at east edge).

 

18" (7/11/05) - Magellan Observatory, Australia): at 228x appeared fairly bright, fairly small, round, 50" diameter with a broad weak concentration.  Forms a pair with NGC 306 5' SE.

 

18" (7/9/02 - Magellan Observatory, Australia): at 128x, this SMC cluster appeared as a small, round, bright knot, ~45" diameter. Forms the southeast vertex of an obtuse triangle with two mag 11 stars ~3.5' NNE and 4' W.  Forms a trio with NGC 306 4.7' SE and Kron 30 3.8' W.  Kron 30 appeared as just a hazy patch, ~1.5' diameter with a few mag 13/14 stars superimposed or resolved.

 

18" (7/6/02 - Magellan Observatory, Australia): this is the first of two small knots of stars (the other being NGC 306) located 26' W of NGC 346.  At 171x, it appeared as a small glowing spot, ~40" in diameter, though standing out fairly well in the field.  The cluster is embedded within a scattered group of brighter stars in the field.  Forms a pair with NGC 306 4.7' SE.  The second edition of Uranometria 2000.0 and DSFG incorrectly list both objects twice - as open clusters and bright nebulae.

 

John Herschel discovered NGC 299 = h2360 on 12 Aug 1834 (sweep 482) and recorded "F; vS; R; gradually little brighter middle; r; 15"."  His final observation on 5 Nov 1836 (sweep 745) reads, "pB, vS, R, 12", resolvable. Situated at the upper limit of the nubecula which here is starry. At the other it is nebulous."

 

James Dunlop possibly discovered NGC 299 earlier on 5 Sep 1826.  Dunlop's D 50, 51 and 52 were described as three small, faint nebulae in a line with orientation NW to SE and his position is 17' to the NE of NGC 299 and NGC 306.  Although the positions are a poor match, the orientation and separations of the two clusters match up well (with two of Dunlop's numbers), suggesting that NGC 299 is D 50 or D 51.  NGC 306, though, might be too faint for Dunlop's 9" speculum reflector, so perhaps his orientation is a coincidence.

 

This cluster is misclassified as a Bright Nebula in the RNGC, and the wrong type was copied into the NGC 2000.0 and first edition of the Uranometria 2000.0.

25" (10/21/17 - OzSky): at 187x; bright, extremely large, irregular, elongated roughly 5:3 WNW-ESE, at least 15'x9'.  Contains a large, brighter core region with a mag 11.5 star at the ENE edge of the core.  A mag 9.6 star is in the halo (along a faint spiral arm), 2.6' SW of center and a mag 10.6 star is superimposed in the outer halo, 5.3' SE of center. Spiral structure was surprisingly subtle. A low contrast, broad inner arm extends W from the N side of the core, curls S on the W side and spreads out. A more obvious inner arm emerges from the S side of the core and sweeps E and N, though the root of the arm is not defined.

 

The arm passes through a relatively bright and large HII patch/OB association, ~25" diameter, situated 3.9' E of center and loses contrast further N. This giant HII complex is catalogued as #65 in a 1966 paper by Sersic and #137 in a 1988 study by Deharveng et al, "H II regions in NGC 300."  A mag 11.5 star is 2.3' further NE in the outer halo of the galaxy. I didn't have time to examine the galaxy at higher power to search for additional H II knots.

 

13.1" (9/22/84): fairly large oval 3:2 WNW-ESE, very diffuse appearance, bright stellar nucleus.  There is a hint of structure although the galaxy has a low surface brightness and was viewed at a low elevation (13° at most) from my latitude of +38.5°.  This nearby galaxy is located at a distance of 6 million light years in the Sculptor group, and may be physically paired with NGC 55.

 

15x50 IS binoculars: (11/18/06): visible in binoculars as a relatively large, very low surface brightness hazy region, roughly 15' in size.  A star is superimposed on the SW side.

 

James Dunlop discovered NGC 300 = D 530 = h2359 on 5 Aug 1826 with his 9" speculum reflector.  Based on 3 observation he described "a pretty large faint nebula, irregular round figure, 6' or 7' diameter, easily resolvable into exceedingly minute stars, with four or five stars of more considerable magnitude; slight compression of stars to the centre." There are several superimposed Milky Way stars.  In his first observation, he noted "a pretty bright small star south of it [probably mag 8.7 HD 5229] - and two or three minute stars north, and following involved in the nebula."

 

John Herschel observed the galaxy on 3 occasions. On the first sweep (1 Sep 1834) he described it as "B; vL; vgpmbM; vmE; irregular figure; 8' to 10' long, 3' or 4' broad; has subordinate nuclei."  His sketch (plate V, figure 10) includes the nucleus and two or three additional regions of nebulosity. Three nights later, he noted it as "faint, very large, very gradually brighter towards the middle; 4' long; 2' broad; has another nebula attached."  The secondary nebula is the large HII complex [DCL88] 137 on the east side.  On 30 Nov 1837 he wrote: "A large oval nebula, containing three stars." He had tentatively identified it with Dunlop 530, but noted: "Mr. Dunlop's neb 530 is described by him as easily resolvable into very minute stars. Its identity with [NGC 300] is therefore very doubtful."

 

Joseph Turner sketched NGC 300 with the 48" Great Melbourne Telescope on 20 Dec 1875 (plate I, figure 3 in "Observations of the Southern Nebulae..."). The giant HII complex on the east side is clearly shown on the sketch as a distinct oval patch.  Pietro Baracchi obsrerved NGC 300 on 7 Oct 1884 and thought there might be changes based on Herschel's sketch and Turner's sketch.  He wrote "The appearance of this nebula may be greatly altered by the state of the atmosphere; but an inspection of drawings shows some change, I think. The principal change is this, that the patch following does not exist at present, or it must be very much fainter than all the rest."  The galaxy was photographed by Harold Knox-Shaw at the Helwan Observatory between 1909-11 and described as a "spiral with many conensations".

A small equilateral triangle of three mag 11-12 stars is just south.  This is an unimpressive but fairly distinctive asterism in a very sparse field.  RNGC, PGC and RC 3 incorrectly equate NGC 305 with the galaxy UGC 571.

 

John Herschel discovered NGC 305 = h76 on 17 Oct 1825 as "a small cluster of p closely scattered stars".  At Herschel's position is a small unimpressive asterism (not a cluster). MCG, RNGC and RC3 misidentify the galaxy UGC 571 as NGC 305.  HyperLeda now shows NGC 305 as stellar (or stars) and NED correctly identifies the number as "six galactic stars".  Discussed in Malcolm Thomson's "Catalogue Corrections" and Corwin's notes.

18" (7/11/05 - Magellan Observatory, Australia): slightly fainter of a pair with NGC 299 5' NW.  Appeared fairly faint, fairly small, round, 40" diameter, smooth surface brightness, no resolution.  Two mag 12 stars lie 2' E and SE.

 

18" (7/9/02 - Magellan Observatory, Australia): NGC 306 is a slightly smaller and fainter companion of NGC 299, situated 4.7' NW.  At 128x it appeared small, round, fairly faint, ~35" diameter with no sign of resolution. Forms the west vertex of a small triangle with two mag 12 stars ~2' SE and a 2' E.

 

18" (7/6/02 - Magellan Observatory, Australia): this is a fainter of a pair of small SMC clusters with NGC 299 and located 4.7' SE of NGC 299.  At 171x it was just a small, hazy compact knot, ~30" in diameter, with no resolution and fairly even surface brightness to the edge.  A mag 12 star is ~2' SE.  In the same low power field with the impressive NGC 346 located 22' ENE.

 

John Herschel discovered NGC 306 = h2361 on 4 Oct 1836 and recorded "an extremely small faint [in italics] knot of the Nubec. Min. 15" diameter."  His position is accurate.

 

James Dunlop possibly made an earlier discovery on 5 Sep 1826.  Dunlop's D 50, 51 and 52 were described as three small, faint nebulae in a line with orientation NW to SE and his position is 17' to the NE of NGC 299 and NGC 306.  Although the positions are a poor match, the orientation and separations are a good match (perhaps a coincidence?), suggesting either D 51 or D 52 refers to NGC 306.  But I'm not convinced as this cluster may be too faint to have been seen by Dunlop (Herschel only noticed it on 1 of the 4 sweeps that he logged NGC 299!).

John Herschel discovered NGC 307 = h77 on 6 Sep 1831 and logged "pF; S; E; 15"."  His position matches UGC 584 = PGC 3367.  This galaxy is located just south of the central region of AGC 119 but the redshift is only z = .013, which is 3 times less than the other cluster members so it is very unlikely to be a member.

Sir Robert Ball discovered NGC 308 on 31 Dec 1866 while observing the field of NGC 307.  He recorded a faint "Nova" in PA 147° (SE) at a separation of 60" (measured at 52" on 23 Oct 1876).  In this position (51" separation) is a 15th magnitude star that Ball apparently mistook for a very small nebulous object.

 

The RNGC misidentified PGC 3354, an extremely faint galaxy 3' SSW of NGC 307, as NGC 308, though with a poor position.  PGC also repeated this identification.  I listed this RNGC error in my RNGC Corrections #3.  Interestingly, it's possible PGC 3354 was seen by Robert Ball with the 72" on 8 Nov 1866, but it didn't receive a NGC designation.  See Corwin's notes for more.

At a redshift distance of ~260 million light years, NGC 309 is one of the largest and most luminous spiral galaxies known.

 

Wilhelm Tempel discovered NGC 309 = T. 1-4 in 1876 with an 11" refractor at the Arcetri Observatory.  His RA was 10 seconds too small.  Bigourdan measured an accurate position on 26 Oct 1897 as well as by Howe in 1898-99 using the 20" refractor at Chamberlin Observatory.

Sir Robert Ball discovered NGC 310 on 31 Dec 1866 while observing the field of NGC 307.  His placed this object, with respect to NGC 307, at 225" separation in PA 81°.  The offset was measured again on 23 Oct 1876 as 239" in PA 84.8°.  At this position (233" in PA 85°) is a single mag 15.3 star that Harold Corwin identifies as NGC 310.

 

The RNGC and PGC misidentify LEDA 3325895 = PGC 3396 as NGC 310.  This extremely faint galaxy is situated 303" in PA 91° of NGC 307.  As the single star was measured twice and is a much closer fit, this identification is very unlikely.  See Corwin's identification notes under NGC 308.

Herbert Howe measured an accurate position in 1899-00 using the 20" refractor at Chamberlin Observatory (repeated in the IC 2 notes).

John Herschel discovered NGC 323 = h2365 on 3 Oct 1834 and recorded "vF, S, R. The RA may err several seconds. The PD also is not very good."

48" (11/4/21): at 610x; bright, moderately large, roundish, 1' diameter.  Strong concentration with a very bright, slightly elongated core that increased to an intense stellar nucleus.  A fairly low contrast spiral arm is attached on the SE side of the core. It curled around the south side and extended to the NW, fading out west of center.  The northern arm was very weak along the north side of the halo.

 

MCG -02-03-064, an interacting companion with very active star formation and tidal stellar streams, was easily seen detached in the halo on the east side, 30" ESE of center.  It was fairly faint, elongated 2:1 SSW-NNE, 15" long, fairly low nearly even surface brightness.  The two galaxies form Arp 59.

 

17.5" (10/28/89): fairly faint, fairly small, slightly elongated NW-SE, weak concentration.  Located along the west side of a triangle formed by a mag 11.5 star 2.5' N, a mag 12.5 star 3' ESE and a mag 13.5 star 3' SSE.

 

Édouard Stephan discovered NGC 341 = St. 12-9 on 3 Oct 1869 with the 31" reflector at the Marseilles Observatory and recorded an unpublished position 2' NE of center.  He published an accurate micrometric position made on 21 Oct 1881 and recorded "faint; irregularly round; moderately large; a little central condensation; fairly distinct nucleus; seems resolvable."

 

Forms a double system (Arp 59) with NGC 341B = PGC 3627 on the east edge. In the Arp category of spiral galaxies with small, high surface-brightness companions on arms, though NGC 341B may just be an large region of increased star formation activity.  The RC3 doesn't identify this galaxy as NGC 341.

18" (12/3/05): extremely faint, very small, ~12" diameter.  Appears as a very low surface brightness spot with averted vision located 2' W of a 1.2' pair of mag 14 stars.  Forms a very close pair with NGC 344.  Uncertain historical identification due to a poor position at Leander McCormick observatory.

 

18" (11/6/04): extremely faint, small, round, very low surface brightness.  Situated 2' W of a N-S pair of mag 14 stars.  A mag 15 star is 1' N.  NGC 344 close SE was not seen.  The identification of this pair is uncertain.

 

Frank Muller discovered NGC 343 = LM 2-297, along with NGC 344, in 1886 with the 26" refractor at the Leander McCormick Observatory.  This nebula was placed 1' N of NGC 344 but there is nothing at Muller's position.  Corwin suggests NGC 343/NGC 344 are the faint pair of galaxies AM 0055-232 = PGC 133741/PGC 198261, located 2.5 min of RA following Muller's position, but matching in declination.  As the Leander McCormick positions are often well off in RA (but generally good in dec), this candidate is reasonable, though uncertain.  ESO and RNGC apply NGC 343 to a single star 1' N of ESO 475-006 and ESO 475-006 is misidentified as NGC 344 in ESO and RNGC.

Frank Muller discovered NGC 344 = LM 2-298, along with NGC 343, in 1886 with the 26" refractor at the Leander McCormick Observatory..  Muller described both objects as possible stars and his position is 0.3 min of RA east and 1.5' north of ESO 475-006.  Corwin suggests that NGC 343 and NGC 344 may instead refer to a faint pair of galaxies (Arp-Madore 0055-232 = PGC 13374/198261) about 2.5 min of RA due east of Muller's position.  If Muller observed this pair, then NGC 344 (fainter SE component) at B = 17.2 is the faintest discovery at Leander McCormick Observatory with the Clark refractor.

00 59 05 -72 10 36; Tuc

V = 10.3;  Size 14'x11'

 

18" (7/6/02 - Magellan Observatory, Australia): this is the largest HII region in the SMC and an amazing sight at 171x using a UHC filter.  The brightest section is a "bar" extending NW-SE with a well-defined edge along the northern side.  Extending from the central region are two sweeping "arms" or extensions, creating an exaggerated "S" appearance similar to a barred spiral galaxy!  The longer but lower surface brightness arm is attached at the southeast end of the central region and broadly sweeps towards the west, below the bar.  The shorter, but high surface brightness arm is attached at the northwest end and hooks towards the east.  These extensions increase the diameter to 8'-10' in total size!

 

Without the filter, the nebula is set in a rich star field (Hodge Association 45) and a number of stars are superimposed or involved with the nebula, some in the center. NGC 346 hosts 33 O-type stars, several in a small clump including a massive 02-type mag 12.8 star and a mag 12.6 O4-type star.  On the NE side is HD 5980, an ultra-luminous mag 11.3 Wolf-Rayet binary (WN4+O7), one of the brightest stars in the SMC. The surrounding region is rich in fainter stars.

 

NGC 371 is in same low power field 22' NE and NGC 330 lies 21' SW.  The small clusters NGC 306 and 299 lies 22' WSW and 26' W, respectively.

 

10x30mm and 15x50mm: NGC 346 is easily visible in binoculars.

 

James Dunlop discovered NGC 346 = D 25 = h2370 on 1 Aug 1826.  His published description (based on an observation on 5 Sep) reads "pretty large, pretty bright nebula, about 2.25' diameter, irregular round figure, resolvable, very slight condensation, not well defined at the edges."

 

John Herschel lists 5 observations in his Cape catalog: He first observed it on 11 Apr 1834 as "B, L, pmE, pretty gradually much brighter middle, 5', resolvable (ill seen, below the pole)." On a second sweep he called it "Cluster, imperfectly resolved; rather irregular figure; 5' diameter. Not equally condensed about centre; fades imperceptibly; has a double star (12th mag) in centre." His third observation was recorded as "B, L, irregularly round, gradually much brighter middle, 3' or 4' in extent, fades away insensibly." His next sweep was recorded as "B, L, neb with resolvable centre; irregularly extended into a kind of broad train as in figure, gently graduating away to the borders. 6' diameter." His final observation was logged as "B, L, irregular figure, with a star 13th mag in most compressed part."  His published sketch is in the CGH catalogue on plate IV, figure 6.

 

Joseph Turner sketched NGC 346 with the 48" Great Melbourne Telescope on 17 Dec 1875, with an "arm" attached on the NW end of bar, hooking to the east.  It also shows a very small knot of stars about 0.8' NE of center (plate I, figure 4 in "Observations of Southern Nebulae made with the Great Melbourne Telescope 1869 - 1885").  He commented, "It is very unlike H.'s drawing and description; indeed I cannot trace any resemblance between that and its present appearance; and were it not for its position, and the fact that L.S. observed and sketched it on 5th February 1870, I should be in great doubt as to its being the proper object. The position, however, accords with that given by Herschel, and Le Sueur's sketch [unpublished plate VII, figure 79] is, in its general features, very like mine, so that there is no room for doubting its identity. The central portion is by far the brightest, being a cluster of stars so very distinct that they could almost be counted; and the nebula here also appears the most dense. From this point it proceeds s.f. for almost 1' 30", terminating in a few very faint stars. Towards the n.p. direction it forms a complete bend or hook, and is here very faint. A little n.f. the main or central portion is a very small and faint round patch, which at times looks like a cluster of very faint stars, but I cannot with certainty determine whether or not it be stars or only nebula, although the night is an exquisite one, being clear and steady."

 

Although a spectrum taken in 1919 at the Cordoba Observatory of Argentina clearly revealed a gaseous spectrum, Charles Perrine declared "the first true spiral which I have encountered that appears appears to consist almost wholly of gaseous nebulosity." (confusing the spiral morphology with a spiral galaxy).

18" (7/11/05 - Magellan Observatory, Australia): at 228x, this SMC cluster appeared moderately bright and large, round, 1' diameter, weak concentration to center, grainy.  A single star or clump was resolved.  Located 4.5' SE of mag 7.8 HD 6222 (2' pair with a mag 9.8 companion).  Observation made through thin clouds.

 

James Dunlop discovered NGC 361 = D 54 = h2374 on 6 Sep 1826.  After logging mag 7.8 HD 6222 (less than 5' NW), he recorded "a small round pretty well-defined nebula, 15" or 20" diameter."  His position was 7' too far SE, but in the same offset direction as NGC 411 and NGC 458 in the same drift.

 

John Herschel rediscovered NGC 361 on 11 Apr 1834 (sweep 441) and noted "vF, L, oval, very gradually very much brighter in the middle."  He listed the possible equivalence with D 55, which was the next object in the drift and offset 10' E of NGC 361.  D 55 may refer to a pair of stars at 01 03 02 -71 33.2.

25" (10/27/22 - OzSky): at 318x; gorgeous globular that is highly resolved into a few hundred stars over the entire face of the cluster. The halo, which extends roughly to 8', was plastered with a large number of fairly brighter stars overlaying a dense layer of fainter stars.  Strongly concentrated with a bright 2' circular core with a much higher stellar density that extends right up to a very small intensely bright nucleus.  Situated 3.3° ENE of 47 Tucanae at the north tip of the LMC.

 

18" (7/6/02 - Magellan Observatory, Australia): At 228x, NGC 362 appeared very bright and well-resolved into a couple of hundred stars! The rich halo was plastered with stars and extended to nearly 8' diameter. The 2' compressed core was well-concentrated to a blazing center (concentration class III). Stars appeared to stream out of the core in curving spiral lanes. This globular has a classic symmetric appearance with a prominent, round core and halo. NGC 362 is situated just north of the SMC, though 47 Tuc (NGC 104) overshadows the splendor of NGC 362.

 

Naked-eye (11/4/12 - Coromandel Peninsula, New Zealand): this 6.5-magnitude globular was just visible naked-eye to the north of the SMC.

 

James Dunlop discovered NGC 362 = D 62 on 1 Aug 1826.  He described "a beautiful bright round nebula, about 4' diameter, exceedingly condensed. This is a good representation of the 2nd of the Connaissance des Temps [M2] in figure, colour, and distance; it is but a very little easier resolved, rather a brighter white, and perhaps more compact and globular. This is a beautiful globe of white light; resolvable; the stars are very little scattered." He observed the globular 11 times (sketched in Figure 3 of his catalogue) and his published position was 2' NE of center.

 

John Herschel (h2375) reported it with his 18" reflector from the Cape of Good Hope on 12 Aug 1834 as a "Fine, highly condensed globular cluster; pretty suddenly brighter middle; diameter 4'." On 3 Nov 1834 he called it "very bright; very large; pretty suddenly very much brighter middle; round; 5' or 6' diameter; all resolved." Observing the next night, he recorded it as "a globular cluster; vB; very little extended; gradually very much brighter in the middle. Diameter of more condensed part approx. 60 sec in RA; but there are loose stars to a considerably greater distance, stars 13 or 14 mag all nearly equal and distinct, but run into a blaze in centre."

 

There was a 1.0 tmin error in reduction in the NGC position too far west.  This error was noted in Harvard College Observatory NGC corrections based on plates taken with the Bruce telescope at Arequipa between 1898 and 1901 and repeated by Dreyer in the IC 2 notes.

18" (7/6/02 - Magellan Observatory, Australia): at 171x and UHC filter, NGC 371 is a fairly bright, prominent, round SMC nebulous cluster, up to 6' in diameter with a fairly well-defined edge.  The haze has a pretty consistent high surface brightness and seems suspended in a large, scattered cluster or star cloud (Hodge Association 53).  A 5' string of four mag 10-11 stars oriented NW-SE is superimposed on the glow (one is mag 13.0 WR star SMC AB 7) as well as a number of fainter stars.  SMC AB 6, another mag 12 WR binary, is at the south end.  This is an excellent low power field with the striking HII region NGC 346 22' WSW and NGC 395/IC 1624 8'-10' NE.

 

10x30mm and 15x50mm IS binoculars: easily visible along with NGC 346.

 

James Dunlop discovered NGC 371 = D 31 = h2376 on 1 Aug 1826.  Based on 5 observations he described it as "a pretty large unequally bright nebula, about 5' diameter, round figure, resolvable into stars of mixt magnitudes."  His published position was 8' too far south, but the description fits.  On 5 Sep 1826 he wrote "a large faint ill-defined nebula, irregular round figure, easily resolvable, about 5' diameter.  This is the large faint nebula in the northern extremity or what I have called the 3 nebulae in the [Small]] Cloud."

 

John Herschel made 5 observations beginning on 11 Apr 1834, recording "cluster, 6th class; faint, round, 10' diameter, stars 15..18th mag."  The next observation was logged as "vF, L, p rich cluster, 6th class. Stars 14..15th mag." On a third sweep he noted it as "a F, L, p compressed cl of 6th class. 10' diameter. gradually brighter in the middle; stars 12..16th mag - in some parts almost nebulous." The fourth observation was recorded as a "cluster 6th class; stars 12..15th mag, a few = 10th mag and one of 9th mag; much compressed in the middle; fills field and has loose straggling lines and crooks branching off." The final sweep was recorded as "F, L, cl; little compressed; gradually brighter in the middle; 7' diam; resolved into stars 14..16th mag."  Herschel was very uncertain (??) if Dunlop 31 referred to this cluster.

18" (11/18/06): faint triple star resolved at 280x.  The components form a very small equilateral triangle 1' N of a mag 12 star with the components ~10" apart.  The brightest component of the triple is at the north vertex and the other two are mag 15-15.5.  NGC 370 may also refer to this multiple star.

 

J.L.E. Dreyer discovered NGC 372 on 12 Dec 1876 with the 72" at Birr Castle and stated "the last nova [GC 5146 = NGC 372] looks at first sight like a hazy *, the higher power seems to resolve it, at all events sev luminous points were seen. Has a *12 in pos 166.5d, dist, 74"."  This pins down the equivalence with a triple star with a mean position of 01 06 44.6 +32 25 43 (2000).  Heinrich d'Arrest *possibly* also observed this triple star (or one or more of its components) on 7 Oct 1861 and it was catalogued as GC 197 = NGC 370.

J.L.E. Dreyer discovered NGC 373 on 12 Dec 1876 using the 72" at Birr Castle in the NGC 383 group.  His description is simply "vF, vS" but he accurately placed it 428" in PA 225.8° with respect to a mag 12.2 star situated SSW of NGC 382/383.  This offset matches PGC 3946.  This is one of 8 galaxies in the Pisces Group discovered at Birr Castle.  Karl Reinmuth, in his 1926 survey based on Heidelberg plates, described this object as a double nebulous star (there appears to be a very faint star at the NW edge) and Dorothy Carlson, in her 1940 NGC Corrections list, states "nebula + star".

25" (10/17/17 - OzSky): at 397x; very bright, fairly small, irregular or triangular shape, 35"-40" diameter.  A half dozen stars were resolved within the glow surrounded by a much fainter halo.  Brighter and larger NGC 419 lies 20' ESE.

 

Lindsay 60 is 16' ENE (see NGC 419 for notes) and Lindsay 66 is 18' NW.  The latter resolved into three brighter stars in a small string oriented WSW-NNE [length of 21"].  At 397x, the middle "star" was a very small knot, ~6"-8" diameter.  This is probably the core of the cluster. The three stars seem surrounded by an extremely low surface brightness halo.

 

Henize N63 and N64 are a fairly similar pair of compact emission nebulae 27' WNW.  Both are ~30" in diameter and separated by 1.4' NW-SE.  They were easily noticed at 397x with N63 on the NW side slightly brighter.  The contast was increased at 244x through an NPB filter.  A mag 12 star lies 0.7' NW of N63.

 

18" (7/11/05 - Magellan Observatory, Australia): moderately bright, small, round, 30" diameter, a few individual stars or clumps are resolved. A 10' string of stars (Hodge Association 56) passing ~4' N and angles towards the NE.  NGC 419 follows by 20'.  Observation made through thin clouds.

 

James Dunlop discovered NGC 376 = D 36 = h2378, along with NGC 419, on 2 Sep 1826.  He recorded (single observation) "a faint ill-defined nebula, about 1 1/2' diameter."  His reduced position (from a drift) is 9.5' ENE, though matches his offset error in declination (about 3.5') for NGC 419. So despite a size estimate that's too large, the discovery appears highly likely.

 

John Herschel recorded this cluster on two sweeps: on 12 Aug 1834 he logged "pretty faint, small, round, resolvable, pretty compact."  On a later sweep he recorded it as a "globular cluster, a vS, vB knot of visible stars 15 or 20" diameter almost like a solid mass."  His position and description on both sweeps is accurate, although DeLisle Stewart reported erroneously (based on plates taken at Harvard's Aqrequipa station between 1898 and 1901) that this object was a "double star only, components 10" apart at 270° (E-W).  Herschel credited Dunlop as the possible discoverer (D 36) in his General Catalogue but not the Cape Catalog.

24" (1/4/14): nice group of ~75 stars, fairly uniformly distributed in a 6' group.  A triple star (STI 185 = 10.8/12.5 at 9" and a third closer companion) is just north of center.  The cluster is roughly circular with no denser patches, but it does include a number of faint stars so the appearance is fairly rich.  Pretty well detached in the 50' field at 125x (less so on the north side).

 

17.5" (8/16/93): 40 stars mag 11-15 in loose 6' diameter, stands out best at 100x.  The brightest mag 10.8 star is part of a triple along the north side.  Fairly uniform in mag 12/13 stars with a scattering of faint stars, fairly even distribution with no rich regions.  Not recognizable as a cluster at 220x.

 

17.5" (11/2/91): about three dozen stars in 6' diameter, fairly faint, roughly a circular group.  Consists mostly of mag 12/13 stars.  Includes a triple star (10.8/12.5/13 at 8"/~3") and two mag 11 stars on the west side.  Several stars are arranged in strings.  Relatively few stars in center.  A line of mag 10 stars trail off to the north edge of field and the mag 10 star at the end of the string 11' N is a close double star.

 

8": ~30 stars in a circular group, bright curving string to the north.  A mag 8 star is 10' E.

 

William Herschel discovered NGC 381 = H. VIII-64 on 3 Nov 1787 (sweep 774) and noted "a forming cluster of pretty compressed stars."  In his second published catalogued he added "Caroline Herschel disc[overy] 1783".

 

Caroline Herschel is often attributed with the discovery of NGC 381 based on this comment, but her description places the intended cluster west of Gamma Cas (and east of Kappa) forming an isosceles triangle, but NGC 381 follows Gamma.  NGC 225 forms a flat isosceles triangle with the two stars and Wolfgang Steinicke argues this was the observed cluster.  The same conclusion was reached in the August 2007 issue of Sky & Tel.

Supernova SN 2000dk (Type Ia) was discovered 5 days ago (18 Sept.) and was visible as a mag 15.5 "star" at the NW edge of the halo (5" W and 9" north of center).  At the first glance using 280x, the galaxy appeared elongated in the direction of the SN, but in moments of better seeing, the SN was clearly resolved and similar in brightness to the nucleus of NGC 382.

 

17.5" (9/19/87): faint, very small, round.  Forms a double system with much brighter NGC 383 30" NNE in a group.

Sir Robert Ball, an assistant on Lord Rosse's 72" telescope, discovered NGC 400 on 30 Dec 1866.  He placed his object, with respect to GC 217 = NGC 403, at a separation of roughly 110" in PA 291.3°.  At this offset is a very faint star at 01 09 07.7 +32 45 35.  This identification was first given by Hubble in his 1920 paper "Photographic investigations of faint nebulae.  "GC 5153 = NGC 400, described in the same observation by Ball, is also a faint star!

Lawrence Parsons discovered NGC 402 on 7 Oct 1874 with his father's 72" and recorded a "faint nebulous knot" and placed 281.7" in PA 353° from star 1 in the sketch.  This star is 87.3" in PA 177° from NGC 403 and has a position of 01 09 15.7 +32 43 42 (2000).  This offset points to a very faint star at 01 09 13.3 +32 48 23 (2000).  This identification was first given by Hubble in his 1920 paper "Photographic investigations of faint nebulae"

William Herschel discovered NGC 407 = H.

Édouard Stephan (XIII-9) independently discovered the galaxy on 2 Oct 1883 at the Marseilles Observatory and published an accurate position.  Herman Schultz also measured a precise micrometric position and recorded a nearby star as a "nova" (NGC 408).

Herman Schultz discovered NGC 408 = Nova III on 22 Oct 1867 with the 9.6-inch refractor at the Uppsala Observatory.  Schultz placed this object just 8 tsec of RA preceding NGC 410.  At this offset is a mag 14.5 star at 01 10 51.1 +33 09 05 (2000), which almost certainly is his object.  RNGC misidentified PGC 4221 as NGC 408.  This galaxy is 3' SW of NGC 410.  Since Schultz micrometric measurement placed his “nova” due west of NGC 410, the RNGC identification is incorrect.  Dorothy Carlson, in her 1940 paper on NGC errata, also came to this conclusion based on Mount Wilson photographs.  Finally, the RNGC has misinterpreted the NGC description to read "406 F 8S" instead of "410 F 8S".  Bigourdan probably observed PGC 4221 (described as almost stellar) although I missed it with my 17.5".  See Malcolm Thompson's "Catalogue Corrections" and my RNGC Corrections #5.

18" (7/6/02 - Magellan Observatory, Australia): this fairly faint SMC cluster was immediately noticed in the same lower power field while viewing NGC 395/IC 1624 about 20' SW.  At 128x it appeared fairly small, round, ~1.5' diameter, mottled but with no resolution.  Located 5.3' NW of mag 8.6 HD 7031 and 13' ESE of mag 7.4 HD 6623.

 

James Dunlop possibly discovered NGC 411 = D 57? = h2384 on 6 Sep 1826.  He logged "a small faint nebula, about 15" diameter", though the reduced position was 19' too far SE.  But the previous object in the drift was noted as a 7th mag star and assuming this refers to mag 7.4 HD 6623, it was also offset 18' in the same direction.  Some doubt remains as this cluster might be too faint to have been noticed in Dunlop's 9" speculum reflector.

 

John Herschel discovered NGC 411 in Sep 1835 (sweep 625?) and recorded "vF, pL, R, very little brighter middle; 2'."  His position is accurate.  On 5 Nov 1836 (sweep 745) he logged a similar description and position, but Harold Corwin found the RA minute (1 tmin too large) was miscopied into his table of "Stars, Nebulae, and Clusters in the Nubecula Minor" and it received the designations GC 231 and NGC 422.  So, NGC 411 = NGC 422, with NGC 411 the primary designation.  See entry for NGC 422.

Francis Leavenworth discovered NGC 412 = LM 1-26 on 15 Oct 1885 with the 26" Clark refractor at the Leander McCormick Observatory and simply noted "Neb?" There is nothing near Leavenworth's position.  Corwin examined the discovery sketch, but it wasn't of much help and he was unable to recover this object (or even identify it with a star).  ESO lists ESO 541-019 = PGC 3931 as a possible candidate, although this galaxy is 3.8 min of RA west and 19' S of Leavenworth's place.  So, at this time NGC 412 is lost.

17.5" (8/4/97): very faint, diffuse glow located 1.3' SSE of a mag 13.5-14 star. The galaxy is roundish and ~1' in diameter with little or no concentration.  The star to the north is preceded by a mag 14-14.5 star 1.4' W.  The RNGC identification at  01 12 31.5 -02 47 38 is probably incorrect and this number was deleted from DSFG.

 

Francis Leavenworth discovered NGC 413 = LM 2-301 in 1886 with the 26" refractor at Leander McCormick Observatory.  His very rough position (to nearest minute of RA and given as doubtful) is 2 tmin west of MCG -01-04-013 = PGC 4347.  This galaxy is not identified as NGC 413 in the MCG.  RNGC misidentifies MCG -01-04-004, an edge-on galaxy, as NGC 413.

24" (12/12/17): at 375x; moderately bright, fairly small, elongated 21"x14" NW-SE with a very faint halo extending SW-NE.  This is a merged double system with twin nuclei NW-SE, separated by only ~7".  I suspected it to be double at 375x and it was definitely "resolved" at 500x.  The brighter NW nucleus (higher surface brightness) was ~6" diameter and appeared more centered in the halo.  The southeast nucleus (~5" diameter) was nearly attached as a round, tiny "bulge" or knot.

 

17.5" (12/23/89): fairly faint, small, elongated NW-SE.  Third of three with NGC 410 5' NW and NGC 407 8.4' W.  NGC 414 consists of a merged pair of compacts, though they were not resolved.

 

13.1" (9/29/84): faint, thin streak NW-SE, weak concentration.

 

Herman Schultz discovered NGC 414 = Nova IV on 15 Oct 1866 with the 9.6-inch Steinheil & Söhne refractor at Uppsala Observatory.  His micrometric position is accurate.  This appears to be the only galaxy in the NGC that Schultz discovered first.  He independently discovered NGC 20, but it was discovered earlier at Birr Castle.  He discovered NGC 90 but it was found earlier at Birr Castle (GC 40).  Another is NGC 7553, which was discovered earlier (GC 4913) by Lord Rosse's assistant George Stoney. Finally NGC 7571 is probably a duplicate of NGC 7597, discovered previously by Albert Marth.  All his other NGC objects are single or double stars.  Stephan apparently also observed NGC 414 on 2 Oct 1869, while observing NGC 407 and 410.

 

This is a double or merged system with two nuclei.  The companion on the southeast side is catalogued separately as PGC 93079.  Based on Crossley photographs at Lick Observatory, Heber Curtis described NGC 414 as "very small, binuclear.  The almost stellar nuclei are 7" apart in p.a. 142°."

James Dunlop probably discovered NGC 416 = h2386 = D 42 or D 43? on 5 Sep 1826 with his 9" reflector.  He described D 42 as a "round well-defined nebula, about 30" diameter." His position was 13.5' SE of the cluster.  D 43, logged on a separate drift on the same date, was called "a small round nebula, 8" diameter, bright at the centre" and placed 12' ENE.  Either or both entries might apply.

 

John Herschel made 4 certain observations at the Cape.  His earliest was on 11 Apr 1834 (sweep 441), with description "F; S; R; 30".  On other sweeps he noted sizes up to 60" and his positions are accurate.  Herschel didn't reference a Dunlop number, probably because of the poor positions.

James Dunlop discovered NGC 419 = D 38 = h2387 on 1 Aug 1826.  He described D 38 as "a very small oval nebula about 10" diameter, a little brighter in the middle with a very small star south of it.  A star 7 or 8th mag following [HD 7187]."  His position was off by 7' to the SSE (similar offset as NGC 395) and the description matches.  He made a second observation on 6 Sep 1826 and called it "a pretty bright round nebula preceding a star 6th or 7th magnitude, rather elliptical, gradually a little condensed to the center, well defined with two minute stars following but not involved."  His position was off by 4' SE and the description is an exact match.  D 39, recorded on 2 Sep and placed 4' NE, might be another observation although the description is a poor match: "a rather faint nebula, about 2' long, extended in the direction of the meridian, easily resovable."

 

D 39 as a "pretty bright round nebula preceding a star 6th or 7th magnitude [HD 7187].  Rather elliptical, gradually a little condensed to the center.  Well defined with two minute stars [11th mag] following, but not involved." His position was 4.5' to the SE and the description is an excellent match.  D 39 may another observation from 2 Sep 1826.

 

John Herschel reported 4 observations in his Cape catalogue, first on 11 Apr 1834 (sweep 441) as "pB; pL; R; 2'. Has two stars near".  His position and description are accurate.  Herschel gave a possible equivalence with D 36, though that entry more likely applies to NGC 376.

John Herschel, d'Arrest (only once, in moonlight), an observer at Birr Castle and Bigourdan have seen only one nebula, no doubt the following one.”

 

Harold Corwin mentions that since Herschel's commented the "following is the largest", the higher number Herschel designation (III-155 = NGC 421) should apply to the galaxy, but "all the observers have assigned the preceding number (H III-154 = NGC 420)" to the galaxy.

18" (7/11/05 - Magellan Observatory, Australia): very faint, small, 30" diameter, low surface brightness and no hint of resolution.  Follows NGC 411 by 7' and forms the eastern vertex of an equilateral triangle with NGC 411 and a mag 8 star 6' SW.  Observation made through thin haze.

 

18" (7/6/02 - Magellan Observatory, Australia): this faint SMC cluster is located 7' following NGC 411.  At 228x it appeared as just a very faint knot, less than 1' diameter with a low surface brightness and no resolution.  Located 5.5' NE of mag 8.6 HD 7031.

 

John Herschel discovered NGC 422 in 1836 with his 20-foot (18") reflector and it was included as #162 in his catalogue of "Stars, Nebulae, and Clusters in the Nubecula Minor".  His position was 30 seconds of RA west (very small offset at this declination) of ESO 051-SC022 = Kron 65 = Lindsay 87, the faint cluster taken as NGC 422 by all modern sources (ESO, NED, SIMBAD, etc).

 

But Harold Corwin found that the entry #162 in "Stars, Nebulae, and Clusters in the Nubecula Minor" actually derives from Herschel's second observation of NGC 411 = h2384 ("eF; pL; R; gradually little brighter middle 2'.") on sweep 745 (5 Nov 1836) though he accidentally increased the RA by 1.0 tmin.  So, NGC 411 has two entries in this table (both indicated as deriving from a sweep with his 18") -- #162, which is 1.0 minute of RA too large, and #157, which was copied correctly.  Entry #162 later acquired the numbers GC 231 and NGC 422.  So, NGC 422 = NGC 411 with NGC 411 the primary designation.

 

The cluster previously assumed to be NGC 422 was later discovered by DeLisle Stewart on plates taken in 1900 at Harvard's station in Arequipa, Peru and received the designation IC 1641.  Instead, IC 1641 has been misidentified as a very faint cluster (Hodge-Wright 62) just following the real IC 1641.  See Corwin's notes for more.

Lewis Swift discovered NGC 442 = Sw. 5-12 on 21 Oct 1886 with the 16" refractor at the Warner Observatory.  His position is 11 seconds of RA west and 15" south of UGC 789 = PGC 4484.  The bright star mentioned in Swift's description as southeast is northeast of NGC 442.  This was first noted by Knox-Shaw in his 1924 description of the galaxy based on a photograph at the Helwan observatory.

Heinrich d'Arrest discovered NGC 443 = Au 10 = Big. 114 on 8 Oct 1861 with the 11-inch Fraunhofer refractor in Copenhagen.  There is nothing at his single position, but he stated a mag 15 star was 8.3 seconds of time directly west.  UGC 796 is located 9' due north of his position and 8 seconds west of this galaxy is a very faint star, matching d'Arrest's description.  So, this identification is certain.  Édouard Stephan observed the galaxy on 12 Oct 1869 though his rough position was 7' too far north. Bigourdan measured an accurate position (listed as B. 114) and noted d'Arrest's error in the remarks section of his second Comptes Rendus list (1887).

 

Stephane Javelle independently discovered NGC 443 on 17 Oct 1903 with the 30-inch refractor at the Nice Observatory, placed it accurately, and Dreyer recatalogued J. 3-849 as IC 1653.  UGC, MCG (+05-04-005) and CGCG (502-010) label this galaxy IC 1653, although the primary designation should be NGC 443 as there was at least three observations prior to Javelle's.  Malcolm Thomson noted this error in his unpublished "CGCG Corrections".

R.J. Mitchell discovered NGC 444 on 26 Oct 1854 with Lord Rosse's 72" at Birr Castle while observing NGC 452.  The first description reads "vvF ray, elongated NW-SE, without nucleus."  The NGC RA is 28 sec too small but Mitchell's description and sketch clearly identifies NGC 444 = UGC 810 = 4561.  Javelle independently discovered the galaxy on 17 Oct 1903 with the 30" refractor at Nice, assumed it was new and placed it correctly in paper 3-851 (later 1658).  So, NGC 444 = IC 1658 with discovery priority to Mitchell.

Albert Marth discovered NGC 446 = m 38 on 23 Oct 1864 with Lassell's 48-inch on Malta.  There is nothing at Marth's position but Corwin suggests NGC 446 is UGC 818, which is situated exactly 1.0 minute of time east of Marth's position.  Édouard Stephan found this galaxy on 20 Oct 1873, perhaps looking for Marth's object.  His position was only 1' E, though he didn't publish the discovery.  Javelle made another discovery on 20 Aug 1892 with the 30-inch refractor at Nice. His published position became IC 89, which UGC, CGCG, MCG and RC3 label this galaxy.  Karl Reinmuth also made the equivalence NGC 446 = IC 89 in his survey of NGC objects using Heidelberg plates and gives the IC position.  UGC, CGCG (411-010) and RNGC misidentify UGC 794 = PGC 4494 as NGC 446.  This galaxy is located 13 sec of RA east and 7' north of UGC 794, which would require random errors in both directions by Marth instead of a single digit error.

Heinrich d'Arrest discovered NGC 447 = Au 11 on 8 Oct 1861with the 11-inch Fraunhofer refractor in Copenhagen.  His position (measured on 4 nights) is accurate. He noted the mag 11 star that follows by 9.2 seconds of RA and 110" north as well as an involved star about 18-19th magnitude (the star is closer to mag 15).  Auwers included this discovery in his 1862 list of 50 new nebulae.  Stephan observed it on 5 Oct 1869 at Marseilles. A week later on a second observation he apparently discovered NGC 449 and 451.

 

Barnard found this galaxy again, along with NGC 451, on 25 Oct 1888 using the 12-inch refractor at Lick Observatory.  He noted (in his logbook) the "nebula is s.p. comparison star [mag 6 HD 7578] and close n.p. a small star.  A 9 1/2m star is s.f. 3'+/- [should read n.f.], a 12m star is s.f. 1/4'."  His offset in RA from the bright star (~40 seconds of time) matches NGC 447, though his declination is 1.4' too far north (similar offset as IC 1661 = NGC 451).  He reported the discovery directly to Dreyer who recatalogued it as IC 1656.  So, NGC 447 = IC 1656. In Barnard's notebook, he later added the comment "This is NGC 447.  The star is wrongly located in NGC."  See NGC 443 = IC 1653 and NGC 451 = IC 1661 for more duplicate IC entries.

 

Based on the NGC positions, the RNGC has reversed the identifications of NGC 447 and NGC 449 whose correct orientations should be SW-NE.  UGC and CGCG misidentify NGC 447 = PGC 4550 as NGC 449 = IC 1656 and NGC 449 is misidentified as IC 1661 in CGCG.  MCG identifies these galaxies correctly.  These errors were noted in my RNGC Corrections #3 and Corwin's notes.

Édouard Stephan discovered NGC 449 = St. 12-11, as well as NGC 451, on 12 Oct 1869 while observing NGC 443.  His published micrometric position was made 12 years later on 11 Nov 1881 with description "vF, vS, R, very little brighter middle, vF * involved".

 

The RNGC misidentifies NGC 447 as NGC 449 (reversing the identifications of NGC 447 and NGC 449).  CGCG labels NGC 449 as IC 1661. Although it is possible that IC 1661 (discovered by Barnard) is a duplicate observation of NGC 449, Corwin feels it is more likely that IC 1661 applies to NGC 451.  More in my RNGC Corrections #3 and Malcolm Thomson's "CGCG Corrections".

48" (10/22/11): at 610x this double system is dominated by NGC 450, which appeared bright, large, 2.3' diameter. Sharply concentrated with a relatively large 30" bright core, surrounded by a very large, low surface brightness halo.  The halo is slightly asymmetric and more extensive on the west side.

 

Three faint "stars" are superimposed on the east side of the galaxy; two appeared stellar, but the faintest and most westerly object was clearly "soft" at 610x.  These are apparently HII knots in the galaxy and the southeast object is listed in NED as UM 311 from the University of Michigan Emission Line Survey.

 

NGC 450 has a very close companion, UGC 807, which is attached at the northeast side of the halo, 1.4' between centers.  UGC 807 appeared fairly faint, fairly small, elongated 5:2 SW-NE, 0.7'x0.3', even surface brightness except for a very small brighter nucleus.  Despite the fact that UGC 807 appears to form a double system, the companion has a redshift that is over 6x greater than NGC 450, so they are an optical pair.

 

13.1" (9/3/86): very large, diffuse, broad concentration, slightly elongated.  Located 12.5' NE of 38 Ceti.

 

William Herschel discovered NGC 450 = H. III-440 on 1 Oct 1785 (sweep 448).  Just 35 seconds after recording 5.7-mag 38 Ceti, he logged III-440 as  "very faint, very large, requires great attention."  Heinrich d'Arrest later measured an accurate position used in the NGC.  This system is a noninteracting spiral pair with the companion (UGC 807) over 6 times as distant.

E.E. Barnard independently found this galaxy visually, along with NGC 447, on 25 Oct 1888 observing with the 12-inch refractor at Lick Observatory.  He noted it was 6 seconds of time preceding his comparison star (mag 6 HD 7578) and called it "vvF, S, R."  The rediscovery was sent directly to Dreyer who cataloged it again as IC 1661, though his declination was 1.2' too far north (similar error with IC 1656 = NGC 447).  Barnard later wrote in pen in his notebook that "This is NGC 451".  CGCG labels this galaxy IC 1661, though NGC 451 should be the primary designation.

25" (10/15/17 - OzSky): NGC 454 was resolved into a neat contact double system at 244x [28" separation between centers], though better viewed at 397x.  The main component is on the east side and appeared moderately bright, fairly small, elongated ~2:1 E-W, ~50"x25".  At 397x it was sharply concentrated with an extremely high surface brightness elongated core and stellar nucleus. The interacting companion, PGC 4461, appears as an appendage, poking out of the southwest side and was easily seen at 397x. It appeared faint or fairly faint, small, probably elongated ~3:2 N-S, ~20"x14".  On the DSS, this galaxy is highly disrupted with plumes and knots.  A mag 11.9 star lies 1.6' NNW.  Situated 4.7' WSW of mag 8.3 HD 7597.

18" (7/6/02 - Magellan Observatory, Australia): this is the first of an unusual chain of three nebulous clusters with NGC 460 and NGC 465 within 10'.  The best view of the entire group was at 171x using an UHC filter.  At 220x the largest in the trio is NGC 456, appearing as a roundish 3' glow with a very small knot embedded in the SE end (SMC-N83A).  A few stars are superimposed (Hodge Association 61) on the glow.  NGC 460 lies 4' ESE.  Visible in 10x30 IS binoculars.

 

James Dunlop discovered NGC 456 = D 7 = D 10 = h2399 on 1 Aug 1826, along with NGC 460 and NGC 465.  He recorded "a faint round nebula, 35" diameter, with a small star near the south margin [probably mag 10.2 HD 7583], but not involved."  His position was 3' too far SE.  He apparently viewed in again during a short drift on 6 Sep 1826 that included NGC 460 and NGC 465, but his reduced positions were 20'-25' too far ENE. 

 

John Herschel observed this object on at least 3 sweeps from the Cape.  He noted it was the first of 3 nebulous clusters with NGC 460 (observed 4 times) and NGC 465 (recorded once).  In addition, it appears that h2398, which did not enter the GC or NGC, is a 4th observation of NGC 456 but with a poor RA.  Herschel equated D 7 with h2399.

 

NGC 456 was first photographed by Delisle Stewart at Harvard's Arequipa Station between 1898 and 1901 and described as "several cB stars, involved in nebulosity."

By analyzing William Herschel's early "reviews" of bright stars (before his systematic sweeps), Wolfgang Steinicke uncovered that Herschel first discovered the cluster on 8 Aug 1780 using his 6.2" reflector in his second review.  He logged "a little north of this [Phi Cas] are several double, treble, quadrupole stars, very small, this is a very rich spot."

18" (7/6/02 - Magellan Observatory, Australia): this cluster is an outlying member of the SMC to the NE of the main body and 70' SE of NGC 362.  At 228x, it appeared fairly bright, small, 1.5'-2' diameter, brighter core, slightly elongated.  The surface brightness was irregular with some mottling but there was no apparent resolution.  Three mag 10 stars are on the SW edge of the field, 10' from the cluster.

 

James Dunlop discovered NGC 458 = D 60 = h2401 on 6 Sep 1826.  He described "a round well-defined nebula, gradually brighter to the centre, about 25" diameter."  His position is 12' too far E, but correctly matching in declination with HD 6222 (close to  NGC 361), the first object recorded in the drift.

 

John Herschel made 2 observations, recording on 12 Aug 1834 (sweep 482) "F, L, R, very gradually brighter middle, 4' dia."  Herschel noted the equivalence with D 60.

 

NGC 458 was first photographed by Delisle Stewart at Harvard's Arequipa Station between 1898 and 1901 and described in a list of NGC corrections as "probably a cluster, extremely small, close, no neb. seen."  NGC 458 was described as "probably globular" in the 1935 Harvard Observatory Bulletin 899 based on Bruce plates at Arequipa.

18" (7/6/02 - Magellan Observatory, Australia): this is the second of three SMC clusters with NGC 456 and NGC 465 in a chain.  At 128x and UHC filter, two close nebulous patches roughly oriented NW-SE were visible, separated by a dusky lane oriented SW-NE.  The total diameter is ~2.5'.  The northwest component, which corresponds with John Herschel's position, has a very small knot or star (SMC-N84A) at the south end.

 

The fainter southeast section has some stars involved (Lindsay 97), including mag 12.5 Sk 155, a massive O9-type star and mag 14.2 SMC-N84B, an emission-line "star" [resolved by HST as a compact HII knot].  Located 4' ESE of NGC 456 with NGC 465 a similar distance southeast. A mag 10 star is close north.

 

James Dunlop probably discovered NGC 460 = D 8 = D 12? = h2402, along with nearby NGC 456 and NGC 465, on 1 Aug 1826.  He described a "a small oval nebula, about 10" diameter" and his single position is just 2' NE.  He apparently viewed in again during a short drift on 6 Sep 1826 that included NGC 456 and NGC 465, but his reduced positions were 20'-25' too far ENE.

 

John Herschel discovered this SMC cluster/nebula on 11 Apr 1834 (sweep 441) and recorded it 4 times.  He noted it was the second of three nebulous clusters with NGC 456 (observed 3 times) and NGC 465 (observed once).  Herschel placed h2402 at a mean position of 01 14 40 -73 18.2 (2000), which was used in the GC and NGC.  Nevertheless, the declination given in RNGC, Deep Sky Field Guide (first edition only), NGC 2000.0 and Uranometria 2000 Atlas (first edition only) is one degree too far north.  The declination given in ESO is correct.

John Herschel discovered NGC 461 = h2400 on 25 Sep 1834 and recorded "pB, R, gradually little brighter middle, 20 arcseconds".  There is nothing at his position but 30' S is ESO 352-033 = PGC 4636.  He noted in his observation that because he was not able to relocate this galaxy he probably made an error in the declination. So, h2400 = ESO 352-033 = PGC 4636.  The RNGC position is 1.1 tmin too far W and 7' S (17' SW) of this galaxy and it is plotted incorrectly on the first edition of Uranometria 2000.  MCG (-06-04-002) missed assigning the NGC number.

NGC 464

01 19 26.7 +34 57 20; And

 

= ** or asterism of 4*, Gottlieb.  Unlikely identification in the RNGC.

 

Wilhelm Tempel discovered NGC 464 with the 11" refractor at the Arcetri Observatory, Italy, and recorded it in list V at 01 19 33 +34 57.7 (2000).  According to Bigourdan who searched for NGC 464, Tempel's entry may refer to a small asterism of four stars close northeast.  But just 1' W of his position is a 9" pair of mag 14 stars with a mean position of 01 19 26.7 +34 57 20 (2000).  Interestingly, my observing notes with the 17.5" indicate that I thought the close faint double could possibly be a non-stellar object!

 

RNGC and PGC misidentify PGC 4721 as NGC 464.  This extremely faint galaxy is located just 6' W of the NGC position and is missing in the CGCG, MCG and UGC.  But Corwin mentions that although Tempel included this object in his 5th list, the original observation was made by the BD observers with a 78mm refractor and hence the faint RNGC candidate is not plausible. Listed in my RNGC Corrections #5.

18" (7/6/02 - Magellan Observatory, Australia): this is the last in a chain of interesting knots and clusters including NGC 456, NGC 460nw and 460se.  At 171x it appears as a 4' curving chain of stars (Hodge Association 63) with no central concentration situated 4' following NGC 460.  There is possibly some faint haze involved or this is just dim stars (no significant nebulosity shows on the Red DSS 2 image).  The entire complex of stars and nebulosity is ~10' in length and fascinating in a 171x field (29').

 

James Dunlop discovered NGC 465 = D 9 = D 13? = h2404, along with NGC 456 and NGC 460, on 1 Aug 1826. He described "a faint nebula, about 1 1/2' diameter, of an irregular round figure.  His position was 6' too far E, but the description fits.  He apparently viewed in again during a short drift on 6 Sep 1826 that included NGC 456 and NGC 460, but his reduced positions were 20'-25' too far ENE.

 

John Herschel observed the cluster on 4 Oct 1836 (sweep 738) and described it as the third of three "in an irregular line of loose stars and nebula."  This object was only recorded on this one sweep, while NGC 456 and 460 were recorded 3 or 4 times.

 

NGC 465 was first photographed by Delisle Stewart at Harvard's Arequipa Station between 1898 and 1901 and described in a list of NGC corrections as "many stars, but no nebula, perhaps open cluster."

17.5" (12/23/89): extremely faint, small.  A mag 15 star is 1' NW.  Located 10' WNW of NGC 472 = NGC 468.

 

John Herschel discovered NGC 468 = h98 on 22 Nov 1827 and recorded "vF; eS; stellar."  His position was 3.6' south of IC 92 = CGCG 502-029 = PGC 4780, and this galaxy has been assumed to be NGC 468 until recently.

 

In March 2015, Harold Corwin checked Herschel's observing logs (in response to an inquiry from Courtney Seligman about the identity), and found he made an error in reducing the position of NGC 468 by 37 seconds in RA (recording the wrong wire).  Once corrected for an additional 37 seconds, the position of h98 = NGC 468 is a close match with UGC 870 -- a significantly brighter galaxy than IC 92.  Heinrich d'Arrest independently discovered this galaxy on 29 Aug 1862, measured an accurate position, and it was catalogued as NGC 472.  So, NGC 468 = NGC 472.  By historical discovery, the primary designation should be NGC 468, but this galaxy has been known only as NGC 472 up to this time.  See Corwin's notes for the full story.

48" (10/25/14): the outer halo of NGC 474 was examined closely at 375x for evidence of the outer, concentric shells and circular streams that are visible on deep images.  Immediately there was a strong sense of arcs from two or more different shells. The easiest arc to confirm was the outermost on the eastern side, which curves south from a mag 13.3 star situated 3.3' NE of center.  The arc passes through a mag 16.3 star and extends 30°-40°.  A second outer arc on the northeast side is half the distance (~1.6') to the center.  This arc has a stronger curvature and measures roughly 60°.  Only a single outer arc (slightly more difficult to confirm) was noted on the southwest side, 2'-2.5' from center.  My rough sketch shows it also curving ~60°.  Additional inner arcs or ripples were strongly sensed in the main halo of the galaxy, but were too subtle and fleeting to pinpoint locations.  The center was sharply concentrated with a very prominent 1' core.  The core itself was sharply concentrated to a small, blazing nucleus.

 

24" (1/12/13): bright, very large with a huge very low surface brightness halo, extending roughly 4'x3.5' NW-SE.  Very sharply concentrated with a very bright, slightly oval core, ~1.0'x0.8', which increases to a small intense nucleus.  Largest in a trio with NGC 470 5.5' W and NGC 467 16' SW.

17.5" (10/4/97): A stellar object was glimpsed a few times at the plotted position 5.5' NNW of NGC 488.  On the DSS a nearly stellar galaxy (V = 16.5) forms a close pair with a very faint star (V = 16.4) off the NE side.  It's possible that I glimpsed the star, which may be brighter than the galaxy.

 

Bindon Blood Stoney discovered NGC 486, along with NGC 490, 492 and 500, on 6 Dec 1850 (Friday).   Bindon may have been observing with his brother George Johnstone Stoney, who visited Birr Castle several weekends in Fall 1850. The field was observed on four nights, although this object was mentioned twice as only "suspected" (labeled Delta on the sketch in the 1880 publication).  The micrometric position from the 22 Oct 1876 observation is 339" N (PA 353°) of NGC 488.  This corresponds with an extremely faint galaxy along with a faint star.  This galaxy is too faint to be included in CGCG, MCG, RC3, PGC but is now listed in HyperLeda as PGC 1281966.  RNGC, PGC and DSFG misidentify MCG +01-04-037 = PGC 4975 (situated close southwest of NGC 492) as NGC 486.  Discussed in Malcolm Thomson's unpublished Catalogue Corrections.

Lawrence Parsons, the 4th Earl of Rosse, discovered NGC 506 on 7 Nov 1874 during the 8th and last observation of the NGC 499/507 Group.  There is no description but a micrometric measure is given 223.1" in PA 153.7° from mag 7.6 HD 8347 at 01 23 12.1 +33 17 24 (J2000).  There is no object at this offset but the NGC position is further southeast (perhaps Dreyer had additional information) and the NGC description adds "sp 507".  Near this position is a single star given here that Corwin identifies as NGC 506.  RNGC mistakenly equates NGC 506 with NGC 504.

William Herschel discovered NGC 507 = H. III-159 = h108, along with NGC 508, on 12 Sep 1784 (sweep 268). He recorded them together as "Two. Both extremely faint, small, but unequal."  Just earlier in the sweep he discovered NGC 495, 496 and 499 in the galaxy group.  During the same sweep he also found the trio NGC 379, 380 and 383 in the Pisces Group, as well as the pair NGC 407 and 410.

 

John Herschel made 2 observations. On 17 Nov 1827 (sweep 104) he noted "extremely faint" and 5 nights later, "pretty bright".

17.5" (10/4/97): this is a faint and difficult double star that was just resolved at 280x.  The fainter eastern component is difficult to cleanly resolve [separation 8"] and it is easy to imagine that Schultz would mistake this oibject as nonstellar.  Located 7' ESE of NGC 499 and 9' WNW of NGC 515 in the field of the NGC 507 Group. The RNGC mislabels PGC 5102 as NGC 510.

 

Herman Schultz discovered NGC 510 = Nova V on 11 Nov 1866 with the 9.6-inch refractor at Uppsala Observatory.  At Schultz's micrometric position (44 seconds following NGC 499) is a close, faint double star (also observed by Bigourdan) with a separation of 8" and mean position of 01 23 55.6 +33 29 49.  The RNGC and PGC misidentify PGC 5102 as NGC 510.  PGC 5102 is 32 sec east in RA and 3' S of NGC 499.  Discussed in  Malcolm Thomson's "Catalogue Corrections".

William Herschel discovered NGC 513 = H.

In this case, Herschel's RA is off by ~30 seconds from UGC 953.  John Herschel made the single observation "F; S" in Nov. 1827 (sweep 105) and measured a good position.

 

The RA in the RNGC is also 0.6 min too far west and the galaxy is misplotted on the first version of Uranometria 2000. The position is given correctly in UGC and RC3.  See Corwin's notes.

8" (1/1/84): faint, moderately large, very diffuse, even surface brightness.  A mag 9 star off the east edge interferes with viewing.

 

William Herschel discovered NGC 514 = H. II-252 = h112 on 16 Oct 1784 (sweep 295).  His description reads, "F, pL, oval, little brighter middle, preceding a pretty bright star." John Herschel reported on 17 Oct 1825 (sweep 15), "vL; irr R; very gradually little brighter middle; by diagram at least 3' in diameter; a remarkable object.  Is closely followed by the double star h13; see fig. 38."

 

The galaxy was observed 6 times at Birr Castle.  The earliest observation on 13 Dec 1848 noted "John Herschel's D* [referring to h 13] is triple and perhaps quadruple.  2 nuclei or nucleus and star in nebula."  The NGC position is accurate.

48" (10/22/11): the view of this very bright, highly irregular, disrupted galaxy (merging pair) was fascinating at 488x.  The most prominent feature is a very high surface brightness curving "bar" oriented NW-SE (VV 231a), bending out in the middle towards the southwest, and fading out on the southeast end with a faint extension.  The total length of the banana-shaped bar is close to 2.5'.  The brightest part is at the northwest end, where there is a large, bright knot (the northern nucleus), 24" diameter that increases to the center.  The edge of the bar is very well defined along the north side.  At the southeast end of the main bar, the brightness dims sharply but a much fainter hazy glow continues further southeast (VV 231c) and spreads out.

 

On the south side is a fairly bright, elongated section oriented WNW-ESE (VV 231b), that is separated from the northern "bar" by a prominent, irregular dark lane running NW to SE, paralleling the bar in the central region. A slightly brighter "knot" is located is the middle of the southern section (the dust lane just north of this knot optically obscures the southern nucleus).  At the southeast end, the glow dims rapidly and fans out further southeast.

 

18" (10/19/06): bright, fairly large, very elongated 3:1 NNW-SSE, 2'x0.6'.  This disturbed galaxy has a very unusual appearance with a bright knot at the NNW end.  The SSE end is wider and fainter and appears to feather out with a fainter, more delicate section that branches from the main body (VV 231b).  The periphery at the SSE end is difficult to trace due to this chaotic structure.

 

17.5" (1/1/92): fairly bright, moderately large, elongated 5:2 NW-SE, 3.0'x1.2'.  Very unusual appearance; the NW portion is noticeably brighter with a bright knot at the NW tip and a mottled texture.  Fades towards the SE where it merges into a fainter section which is tilted ~E-W with an irregular surface brightness and ill-defined edges.

 

14.5" (12/17/20): fascinating galaxy (mid-stage merger) at 226x.  Appears very elongated 3:1 NW-SE with a brighter central region, ~2' length. A much more prominent knot is at the NW end (nucleus of the northern galaxy)! The SE end is more diffuse and feathers out.  Appears brighter (bar) along the major axis.  The galaxy almost mimics a comet in appearance.

 

8" (11/28/81): faint, diffuse, elongated N-S.

 

William Herschel discovered NGC 520 = H. III-253 = h116 on 13 Dec 1784 (sweep 338) and remarked "eF, cL, E."  On 3 Dec 1787 (sweep 788), he reported "cL, E from sp to nf."  John Herschel reported on 16 Oct 1827, "pB; E like a comet, pos 135°±; 60" length".  Using LdR's 72", Bindon Stoney wrote on 18 Dec 1851, "South end is like a brush or broom with a split in it."  His sketch was included in the 1861 publication (as well as 1880). A second observation on 9 Nov 1876 reads "Lord Rosse thought it had two points of condensation 3/4' apart.  I (Dreyer) thought it spread out in the following end like a fan.  Not well seen."  This galaxy is in Arp's category of disturbed galaxies with interior absorption.

48" (11/5/21): at 488x; very bright, very elongated 3:1 or 4:1 ~E-W, with an unusual misshapen structure.  The brightest part extends ~40" E-W in a thin bright "bar", connecting a superimposed mag ~14.5 star (west side) and a bright 15" knot on the east side (the knot is possibly the nucleus of a merging galaxy) . A second slightly brighter "core" (of main galaxy) lies along the bar, midway between the star and knot.

 

The main body flares or widens on the east end and a very low surface brightness plume continues east. A brighter (but still faint) thin extension is west of the superimposed star for a total length of ~1.25'.

 

24" (11/24/14): fairly bright, moderately bright, very elongated 7:2 ~E-W, ~1.1'x0.3'.  This disrupted galaxy (or merger) appeared very asymmetric, widening a bit at the east end and tapering slightly to the west.  A small, relatively bright knot, ~10" diameter, is at the east end.  An easily visible mag 14-14.5 star is embedded at the west end.  The main body, which extends ~40" from the knot to the star, is fairly thin and only very weakly brighter in the center.  With careful viewing, a very faint narrow plume extends west of the main glow.

 

13.1" (12/22/84): moderately bright, thin edge-on 4:1 ~E-W.  Located north of the NGC 483-517 cluster.

 

Heinrich d'Arrest found NGC 523 on 23 Aug 1862 and described this galaxy as a "Double Nebula, F, S, both very near.  A *11 precedes by 11.65 seconds."  As he noted this object as a "Nebula duplex", he apparently saw the knot at the east end (identified in NED as NGC 523 NED02).  William Herschel probably made the first discovery on 13 Sep 1784 (problematic sweep 271) and simply noted H. III-170 = NGC 537 as "stellar".  His RA readings for objects in this sweep are poor (given to the nearest minute) and assuming H. III-170 has an error of about 55 sec in RA, then NGC 523 = NGC 537.  The eastern knot was the site of SN 2001EN.

Heinrich d'Arrest discovered NGC 528, which was missed by both Herschels, on 22 Aug 1865 with the 11-inch refractor at Copenhagen.  His single position is quite accurate.

 

In March 2020, Yann Pothier found that Bindon Blood Stoney, Lord Rosse's assistant, made an earlier discovery on 7 Nov 1850.  A diagram in the 1880 publication shows two nebulae with distances to nearby stars.  Although the orientation for west is off (the arrow should be pointing down) the separations are a perfect match with NGC 513 (discovered by William Herschel) and NGC 528.  A later observation on 27 Nov 1857 by R.J. Mitchell mentions a similar diagram was made, so NGC 528.was seen twice at Birr Castle before d'Arrest's observation.  Dreyer questioned if the two nebulae were novae but he wasn't left with any positions, so d'Arrest was credited in the NGC.

William Herschel discovered NGC 536 = H.

III-171 is 1.0 min of RA east of UGC 1013.  John Herschel made a single observation in Nov. 1827 (sweep 105) and recorded "pB; pL; gradually brighter in the middle; the following of two." His position was accurate.  Heinrich d'Arrest made 3 observations and mentioned the star involved on the north side.

 

Analyzing the sweep data, Harold Corwin suggests H. III-171 applies to NGC 529, which is 1 min 40 sec of RA west of Herschel's place, but Wolfgang Steinicke argues that H. III-171 must apply to NGC 536 (coming from the previous object NGC 537 in the sweep).

Francis Leavenworth discovered NGC 539 = LM 1-28 on 31 Oct 1885 with the 26" refractor at Leander McCormick Observatory.  His rough position is just 1' to 2' S of ESO 542-010 = PGC 5269.  NGC 563 (found again by Leavenworth the next year) is a duplicate observation with a 2 tmin error in RA.  So, NGC 539 = NGC 563.

John Herschel discovered NGC 549 = h2413 on 29 Nov 1837 and recorded "eeeF, S, R, very gradually brighter middle. The 4th of a group of four [with NGC 534, 544 and 546]."  There is nothing at this position, but 15' N is ESO 296-026 = PGC 5278, and ESO, SGC and RC3 identify ESO 296-026 = NGC 549. These galaxies were observed on two sweeps and given very accurate positions.

 

Instead, I suggested that NGC 549 = ESO 296-022 = PGC 5243. This galaxy matches Herschel's position in declination but his RA would be off by 18 tsec.  Although ESO 296-022 is much smaller and fainter than ESO 296-026, it is closer in position (off only in RA) and a much better match with Herschel's description "The 4th of a group of 4" [with NGC 534, 544 and 546].  So, although the identification of NGC 549 is not definite, NGC 549 = PGC 5243 appears to be a much better choice.  See Corwin's identification notes.

 

This identification was suggested by Pietro Baracchi, when he observed the group with the 48" Melbourne telescope on 19 Dec 1887.  He noted "GC 324 [NGC 549] found but out of position...It is eeF; eS; R."  It precedes [NGC 544] by 6s and is 5' 10" north of it.  In this group [GC] 316, 320, 321 agree with Herschel in appearance, relative and absolute position, but 324 [NGC 549] is out altogether.  It agrees very well in appearance but its relative position with regard to the other three objects is quite different.  Herschel observed [NGC 549] only once and the other three were observed twice - it is probable that he made some mistake in placing or connecting the four objects together."

17.5" (12/9/01): this number possibly applies to the mag 15 star just 30" preceding CGCG 502-084, assuming NGC 553 applies to CGCG 502-084.  The star was actually slightly easier to view than the galaxy.

 

William Herschel discovered NGC 552 = H. III-172, along with NGC 553, on 13 Sep 1784 (problematic sweep 271).  He listed both together as "Two. Both very small, stellar; but a little doubtful."

This identification is very uncertain due to a poor position by William Herschel.

 

William Herschel discovered NGC 553 = H. III-173, along with NGC 552, on 13 Sep 1784 (problematic sweep 271).  He recorded both as "Two [with NGC 552 = III-172]. Both vS. stellar, but a little doubtful."  There is nothing near his position and RNGC classifies NGC 553 as nonexistent.  Dreyer notes the observation by Sir Robert Ball at Birr Castle on 4 Jan 1867 ("Two, perhaps 3 neb, but I had not time to examine the field closely.  Alpha is faint, very small; Beta extremely faint; Gamma is doubtful") may refer to other objects.

 

Harold Corwin suggests that NGC 553 is possibly CGCG 502-084 = PGC 5333.  NGC 552 might apply to the faint star close preceding.  This assumes Herschel's RA was 1.6 minutes too large, and his dec 3' too far north (his errors in RA were greater as the sweep progressed).  But Wolfgang Steinicke disagrees. He argues that Herschel's sweep path from III-171 = NGC 536, the previous object in the sweep, is not consistent with CGCG 502-084, which is too far west and south to be seen.  So, perhaps it is best to classify NGC 553 and 552 as lost (likely stars).

Lewis Swift discovered NGC 557 = Sw. 6-11 on 20 Nov 1886 with the 16" refractor at the Warner Observatory and recorded "eF; S; B * f 15 seconds and is on of it."  His position is poor; 46 sec of RA east of UGC 1016 = PGC 5351 and the bright star is southeast of the galaxy, but the identification NGC 557 = UGC 1016 is secure.  Bigourdan couldn't find the galaxy at Swift's position but "rediscovered" it on 27 Oct 1897 assuming it was new.  Big. 369 (later IC 1703) has an accurate position.  So, NGC 557 = IC 170, with NGC 557 the primary designation.  UGC and CGCG label this galaxy as IC 1703 but RC3 identifies it as NGC 557.

17.5" (11/2/91): about 50 stars mag 10-15 at 220x in a 6'x4' region.  Fairly compact and rich with an irregular outline.  Includes a thin isosceles triangle of three mag 10 stars with the base to the south.  The southeast star in this base is a close unequal double.  A number of the stars are arranged in strings including four mag 13-14 stars over haze trail from base to the north.  Also four mag 8/9 stars precede the cluster to the northwest in a 10' string.

 

William Herschel discovered NGC 559 = H.

Heinrich d'Arrest measured an accurate postion on 5 Jan 1864.  Édouard Stephan found the galaxy on 4 Nov 1875 (already aware of it?).  He reported it as new (list 8b, #1) with an accurate position determined on 21 Nov 1878, but added a footnote that it was probably equal to H.

Wilhelm Tempel independently found the galaxy on 14 Aug 1877 with the 11" refractor at the Arcetri Observatory and recorded it in both his first discovery paper (#7) and his 4th paper.  Tempel claimed he found two nebulae 2m 50s following NGC 560 and 564 (there is only a single galaxy at this position), which Dreyer assigned to NGC 577 and NGC 580. His description in the first table reads, "Near the star Lalande 2666, which has in its field the nebulae III 441-42, are still two more nebulae following by 2m 50s, one as bright as the preceding of Herschel's."  In the 4th paper he described only a single nebula, "II class, somewhat brighter than the two preceding nebulae, H.

Two spiral arms were obvious - the northern spiral arm was detached from the bar and seemed to start just north of the eastern end of the bar.  It swept roughly due west in the northern halo, with a brighter, patchy section to the NW of the bar.  The southern arm was nearly attached to the west end of the bar and was easily seen shooting straight east.  It was fairly thin and well defined, with a slightly brighter section to the SE of the bar.  There was a strong suggestion of a third arm extending west, with an isolated section on the south side of the halo.

 

An easily visible, relatively large "knot",  ~15" diameter, was noticed immediately on the east side [1.0' ENE from center], though it's not embedded in one of the arms.  I assumed at the time it was a giant HII region, but images revealed it's an overlapped background galaxy (LEDA 133775).  A second background galaxy, LEDA 810586, is just beyond the western edge.  It appeared as a fairly faint, thin edge-on 5:1 E-W, ~30"x6".

Wilhelm Tempel found NGC 580 = T. 1-8 = Sw. 6-12 on 14 Aug 1877 with the 11" refractor at the Arcetri Observatory, claiming to see two nebulae 2m 50s following NGC 560 and 564.  The second object was assigned NGC 580. But there is only the single galaxy UGC 1080 = PGC 5628 at this position, so possibly one of his objects was a faint star. NGC 580 is generally equated with NGC 577. Aaron Skinner discovered this galaxy 10 years earlier on 23 Oct 1867 with the 18.5-inch Clark refractor at Dearborn.  As the discovery wasn't published until 1887, Skinner wasn't credited in the NGC.

 

Lewis Swift found the galaxy again on 20 Nov 1886 and reported it as new in his 6th discovery list.  Dreyer assigned Swift's position to NGC 580 with Swift and Tempel credited in the NGC.  Herbert Howe measured an accurate position in 1899-00 using the 20" refractor at Chamberlin Observatory.

V = 7.4;  Size 6'

 

13.1" (10/20/84): 50-60 stars in cluster, fairly rich.  Includes several bright stars in a distinctive triangular wedge shape.  At the NW edge is STF 131, a triple consisting of mag 7.3 HD 9311 (background star), a 9.9-mag star at 14" and an 11.8-mag star at 28".  Mag 8.4 SAO 11826, a colorful orange M2-class supergiant, is just SE of center with mag 8.9 SAO 11824 only 1' S.  Mag 8.2 HD 9365 is on the SE edge and lies in the foreground.

 

Pierre Méchain discovered M103 = NGC 581 = h126 in April 1781.  Messier added it at the last minute to his 1781 catalogue (published in the 1784 Connaissance des temps), but since the discovery occurred after the manuscript was sent out for publication, he wasn't able to provide visual confirmation or specific coordinates.

 

William Herschel observed the cluster on 8 Aug 1783 and wrote, "14 or 16 pretty large stars with a great many extremely small ones. Two of the large ones are double, one of the 1st the other of the 2nd class. The compound eye glass shews a few more that may be taken into the cluster so as to make about 20. I exclude a good many straggling ones, otherwise there would be no knowing where to stop."  On 3 Nov 1787 (sweep 774) he called it "a cluster of pretty large stars, 5 or 6' diam, pretty compressed, irregularly round."

 

John Herschel included M103 in his Slough Catalogue (h126) but only referenced STF 131, Wilhelm Struve's entry (1825) from his catalogue of double stars, so he was apparently unaware of the equivalence with M103. He reported it on 29 Sep 1829 (sweep 213) as "A fine cluster; round; rich; rather coarse; 6 or 8' diam; stars 10...11m. One of Struve's "acervi" [heap of stars].

William Herschel discovered NGC 584 = H. I-100 = h128, along with NGC 586, on 10 Sep 1785 (sweep 435). He recorded both as "two, the first [NGC 584] cB, pS, R, mbM.  The second [NGC 586] eF, S, about 5 or 6' following the former, requires great attention to be seen.  His position is fairly accurate.  John Herschel made 3 observations, desribing it on 9 Oct 1826 (sweep 186) as "vB; R; pretty suddenly brighter middle; 25" [diameter]."

 

E.E. Barnard found this galaxy while observing his comet discovery C/1888 RI with the comet nearly occulting the galaxy!  He wrote, "The comet's nucleus passed some 30" N of the nucleus of the nebula.  The comet is probably 5 times as bright as the nebula and is a great many times larger."  The discovery was reported directly to Dreyer, who catalogued it again as IC 1712.  As Barnard's position is nearly identical to NGC 584, it's strange Dreyer didn't noticed the equivalence, though Barnard later added in his notebook "NGC 584".

William Herschel discovered NGC 586 = H. III-431 = h130 = Sw. 3-6 on 10 Sep 1785 (sweep 435) along with NGC 584. See description under NGC 584.  John Herschel made a single observation on 8 Jan 1831 (sweep 318), "vF; R; 15 arcsec".

 

R.J. Mitchell observed NGC 586 with the 72" on 28 and 29 Nov 1856.  John Herschel catalogued the Birr Castle observations as a new discovery: GC 343 = R[osse]. nova.  But in compiling the 1880 Rosse Catalogue Dreyer noted the equivalence with h130 = III 431.

 

Lewis Swift apparently thought he discovered this object on 30 Nov 1885, though his position for Sw. 3-6 was 19 seconds of time too far east.  His description stated "south-following GC 363 [NGC 615], but this must be a typo.

Heinrich d'Arrest discovered NGC 587 on 27 Aug 1862 with the 11-inch refractor at Copenhagen.  His single position is 4.5' S of UGC 1100.  Although this is an unusually large error there are no other candidates nearby.  Stephan made an unpublished observation on 2 Oct 1869, with his position 3' E of center and another on 22 Nov 1875 (2' E of center).

 

The CGCG, UGC and PGC label this galaxy IC 1713, although according to Malcolm Thomson, Bigourdan's micrometric position for Big. 247 = IC 1713 on 28 Nov 1891 clearly refers to a faint star near NGC 587.  Bigourdan also determined the position of NGC 587, so NGC 587 cannot be equal to IC 1713.  See Corwin's notes.

Bindon Blood Stoney or George Johnstone Stoney, Lord Rosse's assistants, discovered NGC 595 = Sf. 63 on 27 Dec 1850 (Friday). An offset was measured from a star superimposed on M33.  It was possibly first seen on Sept. 13, though the description on that date only mentions "full of knots").  The nebula was labeled as "1" on the diagram in the 1861 publication.  No coordinates were ever measured at Birr Castle.

 

Heinrich d'Arrest independently discovered this HII knot on 1 Oct 1864 with the 11-inch refractor at Copenhagen and measured a fairly accurate position (4 seconds of RA too large).  d'Arrest is credited with the discovery in the NGC. Truman Safford rediscovered it on 1 Nov 1866 with the 18.5" refractor at the Dearborn Observatory and recorded Sf. 63 as "pF, vS, probably a well-known outlier of M33."

Gioivanni Hodierna possibly discovered M33 = NGC 598 = H. V-17 = h131 before 1654 and catalogued it as a cloud-like nebulosity or obscuration "near the Triangle".  Charles Messier made a certain discovery of M33 on 25 Aug 1764.  William Herschel first viewed the galaxy with his 6.2" on 2 Aug 1783 and again three weeks later (24 Aug) he wrote (57x), "There is a suspicion that the nebula consists of exceedingly small stars. With this low power it has a nebulous appearance; and it vanishes when I put on the higher magnifying powers of 278 and 460."

 

William Herschel first viewed M33 with his 18.7" on 11 Sep 1784 (sweep 266) but didn't recognize it as M33, perhaps as it wasn't located at Messier's position.  He wrote, "18' long, and about 8 or 10' broad, or near 12' in the middle, faint, brightest and broadest in the middle.  To the [north] of it is a small round nebula [NGC 604], brightest in the middle, very faint.  The ends lose themselves nearly in the meridian or from a little SW to NE.  There is also a roundish places which seems brighter than the rest and is almost detached enough to form a different nebula but may perhaps belong to the same."  Another observation was made the next night (sweep 267) and he measured the polar distance of the "small nebula" [NGC 604].  On 11 Jan 1787 (sweep 680) he noted "The large nebula [no identification]. The middle of it easily resolvable and some of the stars visible; it is impossible to say how far it may extend; the nebulosity losing itself so gradually, but goes undoubtedly a great way in every direction, but chiefly from sp to nf."  Caroline added a memorandum in her sweep record that he "Looked for the 33rd of the Conoiss des Temps, but it is not in the place."  So clearly there was still confusion about the identification of M33, which overfilled they eyepiece field.  Again in 1785 PT paper, Herschel mentioned his two observations as an example of an extended "milky Ray", but didn't refer to it as M33, and included it as new nebula in his first catalogue (V. 17).  In observations made after his sweeps had ended, Herschel seemed to treat M33 as a cluster.  Using "Large 10 feet telescope" (24" f/5) in 1805 and 1810, he wrote "The condensation of the stars is very gradually towards the middle; but with the four powers 71, 108, 171, and 220, some nebulosity remains. The stars of the cluster are the smallest points imaginable."

 

John Herschel included only a single observation in the Slough Catalogue from 15 Sep 1828 (sweep 177): "Enormously L; very gradually brighter middle.  The nucl taken; has a * 12m, nf the nucl.  The diffused neb extends 15' s[outh] and as much nearly to n[orth].  It has irregularities of light, and even feeble subordinate nuclei [HII knots] and many small stars."

 

Lord Rosse and/or assistant George Johnstone Stoney observed spiral sturcture in M33 on 6 Sep 1849 and a drawing by Rosse on the 16th with four or more spiral arms was included in the 1850 PT paper (figure 5).  The description reads, "New spiral, s(outh) branch the brightest, none F, nf one short but pB, p(receding) on pretty distinct, sf one but suspected; the whole involved in F neby which probably extends past several knots which lie about it in different directions.  Faint nebulosity seems to extend very far following."  R.J. Mitchell produced a more detailed drawing on 18 Dec 1857 (included in the 1861 publication).  Isaac Roberts produced the first excellent photograph of M33 in 1895 with his 20" reflector, revealing more detail than seen visually.

 

Based on the discovery of three dozen Cepheids by 1926, Edwin Hubble found a distance of ~860,000 l.y. using the Period-Luminosity relation.  This determination, along with M31, proved they were external galaxies and effectively ended the "Island Universe" debate.  The actual distance is ~3x larger, due to mixing different types of Cepheids (Population I and II) .

William Herschel discovered NGC 600 = H.

01 29 26 -73 33 36; Hyi

Size 3'

 

25" (10/17/17 - OzSky): at 244x; NGC 602 is a large nebulous cluster (SMC-N90) that was clearly brighter on the southeast end.  The total size is ~3' with the southeast end fairly bright, fairly large, irregular shape.  A tight knot of three stars is near the center. Additional stars are involved near the edges.  A weak dust lane was on the west end oriented SW-NE, separating the roundish western section.  A mag 13.8 star (O3-type Sk 183) is involved just west of the dust lane. This star is one of the massive O-type stars in the SMC and the dominant ionizing source of the nebula.  The two portions are separated (barely) without a filter but tangent when I added a NPB filter.  A mag 12.5 star is off the SW side (1.8' from center) and a mag 13 star is off the north side, 2.2' NNW of center.  NGC 602, along with N89 and N88 to the northwest, is situated in the SMC "Wing", along the boundary of SMC-1 (also called SMC-SGS 1), the only supergiant shell (diameter ~1°) in the SMC.

 

SMC-N89, located 20' NW, is fairly faint, large, roundish, irregular glow, ~3.5' diameter.  At the northeast end are four mag 11.5 to 13 stars (part of Hodge association 67) in a near equilateral triangle with a 4th star at the center and a 12th mag star is at the E or SE end of the nebulosity.   Lindsay 104 is a very faint, unresolved patch (cluster) just southwest of the four distinctive stars. Situated at the western boundary of SMC-1.

 

SMC-N88, located 33' NW, is dominated by a Highly Ionized Blob (HEB) of only 3.5" diameter and mag ~12.5.  At 244x + NPB filter it appeared as a bright "star" or quasi-stellar object surrounded by faint nebulosity on the east and south side.  I assume there was a contrast gain with the filter as this dense, high-excitation object has a ratio of O III lines/H-beta > 10.5.   The nebula is surrounded by Hodge Assoication 64 including a mag 14 star 2' E, two close mag 14 stars 1.8' SE and a mag 14.5 star 1' SSE.  A mag 11.2 star (part of Hodge Associatin 65) lies 5.6' S.  Situated at the NW edge of supershell SMC-1.

 

18" (7/6/02 - Magellan Observatory, Australia): at 228x, a knot of stars is embedded in a 3' fairly bright oval nebula (Henize N90).  On closer inspection the knot of stars is offset to the SE side of the nebula.  At 171x and UHC filter, the nebulosity is fairly bright and clearly locally brighter on the SE end around the knot of stars.  A weak dark rift, running SW-NE, separates the fainter portion of nebulosity to the NW.  This nebulous cluster is an outlying member of the SMC.

 

James Dunlop discovered NGC 602 = D 17 = h2421 on 1 Aug 1826.  He described "a faint round nebula, about 2' diameter, a very little brighter in the middle, with some minute stars in it."  Dunlop's position is just 3' too far east.

 

On 11 Apr 1834 (sweep 411), John Herschel logged "pB, S, irregularly round, pretty suddenly brighter, but not to the middle, but rather to a point near the southern edge. Is decidedly resolved, and has scattered stars. (This is an outlier of the Nubecula Minor)".  On 5 Nov 1836 (sweep 745), he called it "bright; round or little extended; pretty suddenly brighter middle, to a star; has also a star involved which looks like a second nucleus and several small stars about it."

 

Joseph Turner observed this object on 26 Jan 1879 with the 48" Melbourne Telescope and noted there was clearly a double star in the center.

17.5" (9/28/02): identified at 162x as a slightly fuzzy glow and cleanly resolved into a faint triple star at 325x (7.5mm Tak and Paracorr).  Situated ~30' SE of the core of M33.

 

17.5" (8/11/96): this is a faint, close triple star within M33 described as a "A small neb. or Cl. with 3 st[ars] in it" by Lord Rosse.  It appeared as a faint nebulous spot at low power and was barely resolved at 220x.  The trio of mag 14/15 stars was cleanly resolved at 410x.  The maximum separation is 15", the close pair at 9" separation and the other side 12" with the trio forming a 3-4-5 right triangle!  Located 28' SE of the center of M33.

 

Bindon Blood Stoney discovered NGC 603 on 29 Nov 1850 (Friday).  Bindon's brother, George Johnstone, may have participated in the discovery as he visited Birr Castle several weekends in Fall 1850. It was recorded as "A S neb. or Cl. with 3 st in it.  It is about 8' ssp a [double star] whose components are of the 11 m.  RA 1h 26m +/- NPD 60d 35' +/-.  (I obs)."  This description pins down the identification as a triple star whose components have a maximum separation of 15".  In the IC 2 notes, Dreyer mentioned he only saw an extremely faint star on plates of M33.  Karl Reinmuth, in his 1926 survey based on Heidelberg plates, states "Cl of 3 st 14".  This identification was noted by Mayall and Aller (1942) in the article "The Rotation of the Spiral Nebula Messier 33," ApJ, 95, pp. 5-23.  See Corwin's Notes.

NGC 604 = M33-A84 = BCLMP 680

01 34 31.9 +30 47 13; Tri

 

48" (11/5/21): at 488x (unfiltered): NGC 604 appeared very bright, highly structured, with several mag 16.5+ supergiant stars resolved in the HII region.  The main section is roughly 50" in diameter and elongated NW-SE, but with a very irregular outline, particularly on the eastern side.

 

The brightest region has a dented triangular shape, ~15" on each side, with a very high surface brightness along the SW facing edge (W side of NGC 604). Just to the NNW of the triangle is a 15" patch that is nearly detached.  Adding an NPB filter, the nearly detached patch is fully connected and the SW facing flank brightens significantly.  Also the SSE end of the nebula has a small elongated patch that noticeably improved contrast.

 

Very close to the NE vertex of the triangle is a faint Wolf-Rayet star (WR 4, V = 17.4) and a slightly brighter star (WR 2) is close to the S vertex.  Two or three additional very faint stars are within 15" to the east of the triangular region (one is 17.9-mag WR 6).

 

18" (12/10/07): bright, large HII knot in M33 at the end of the spiral arm that trails to the east on the north side of the core.  A mag 10.5-11 star is located 1.5' SE and NGC 604 is elongated 3:2 in the direction of this star.  The outline is oval, though a bit irregular, particularly on the east side.  It appears brighter and mottled on the northwest side and with direct vision a slightly brighter stellaring is embedded near the northwest end.

 

13.1" (7/5/86): bright HII region located 12' NE of the core of M33.  Situated at the end of the large spiral arm of M33 that extends north and then east of the core.  Bright, fairly small, ~30" diameter, round.

 

8": fairly bright, round, knot in M33.

 

William Herschel discovered NGC 604 = H. III-150 = h133 on 11 Sep 1784 (sweep 266) during his first observation of M33 with his 18.7".  He noted it was "very faint, small, round nebula, brightest in the middle."  The sighting was confirmed the next night and was logged again on 11 Jan 1787 (sweep 680) as "the small nebula; small, round" , although he still didn't recognize "the large nebula" as M33.

 

 Lord Rosse or assistant reported on 13 Sep 1850: "large spiral full of knots, north following is a bright, small neb [NGC 604], which on a very good night might appear attached to the spiral, than which it is brighter."  Bindon or George Stoney measured an offset from a star superimposed just north of the core of M33 on 2 Jan 1851 and the nebula was labeled as "3" on the diagram in the 1861 publication.  Vogel first identified its gaseous spectrum in 1890.

There appeared to be a very faint extension or large knot southeast of the core . The DSS reveals this feature to be the bright spiral arm extending southeast from the central bar.  Located 2.4' SW of mag 9 SAO 167149.

William Herschel discovered NGC 613 = H. I-281 = h139 = h2422 = D 621 on 9 Dec 1798 (sweep 1084). He recorded "considerably bright, elongated from north preceding to south following, 5 or 6' long, 1 1/2' broad, a nucleus in the middle. A pretty considerable star is about 3' north of it, and a little following."  NGC 613 is the 10th southern-most galaxy he discovered.

 

James Dunlop independently found the galaxy on 5 Aug 1826, apparently unaware of Herschel's prior discovery (or he thought it was a different object).  He described "a very small round nebula, about 15" diameter, pretty well defined, bright at the center." His position was over 1/2° too far E.  Stephen O'Meara finds it curious that Dunlop failed to note any elongation and didn't mention its proximity to the 10th magnitude star just off its NE flank.

 

John Herschel observed the galaxy both at Slough and at the Cape of Good Hope.  On 27 Sep 1834, his Cape observation reads "vB; vL; vmE; pos 118.3 ; 1st gradually then suddenly much brighter to the middle to a nucleus 4' long 1.5' broad, has a star 9th mag N.f."  He also noted that the position assigned in his Slough Catalogue was incorrect.  On a second sweep, he logged "pB; vmE; pretty suddenly little brighter middle, 2 1/2' length.  No other near it within 3 fields in RA and 1 field's breadth in declination."  Finally on a third sweep he logged "vB; L; vmE; pspmbM; has a *10; N.F."

In the NGC Notes section, Dreyer commented "never found at Birr [in 5 attempts], nor by d'Arrest [in several attempts].  Schönfeld (II) has two observations, vF, eS = *13, place agreeing with [John Herschel].  Query: only a faint star..."  In the IC 1 Notes and Corrections entry for NGC 618 and 627, Dreyer adds "Not observed by John Herschel in the same sweep as [NGC 608 and 614].  Neither of them seen by Burnham."

 

Wolfgang Steinicke suggests NGC 618 may be a mag 10 star at 01 41 36.6 +33 17 40 (J2000) with a mag 12.7 star 30" southwest and a mag 15.7 star 30" south.  Harold Corwin is skeptical that this combo would mimic a "pretty bright" nebula and suggests that NGC 618 is possibly a duplicate observation of NGC 614, although the brighter star following is not at the required separation, unless Herschel meant 51 seconds, instead of 2m 51s.  Wolfgang Steinicke analyzed the sweep data and arrived at a different position, close to 01 42 +33° 23' (J2000), assuming the bright star precedes the object, but this "corrected" position has no "pB" objects nearby.

John Herschel discovered NGC 627 = h141 on 11 Nov 1827 and recorded "vF; R; another precedes; which must be III.174 [NGC 614].  The RA conjectural and PD liable to some error."  Heinrich d'Arrest was unsuccessful in locating an object at Herschel's position and he commented "is not in the heavens. Anyway, the place assigned [by Herschel] as doubtful, is errant."

 

Sherburne Burnham (Publ of the Lick Observatory, Vol II) was also unable to find the object and Dreyer concluded "should be struck out" in the IC 1 notes section.  Burnham suggested this might be a duplicate observation of NGC 614 in which case the object that preceded would be NGC 608 (misidentified as III 174).  But Wolfgang Steinicke argues that NGC 614 is located 2.4° due north of ∑137, the previous object in the sweep, so he could not have arrived at the field of NGC 614 as the next object. See Corwin's identification notes for more.

V = 9.4;  Size 10.5'x9.5';  Surf Br = 14.2

 

48" (10/22/11): beautiful face-on spiral with long, graceful arms wrapping around an intense 1' core that increases towards the center, but there is no sharp nucleus.  At first glance at 375x there appeared to be four arms, but with a more careful look there are two main arms that each wrap more than 360° around the core as well as a couple of side branches.  Each arm is studded with a number of non-stellar HII regions that highlight the arms.  In addition, a number of stars are superimposed, both in the inner region (two faint stars are within 25" of the center) and around the edge of the halo, which extends to 7'-8' diameter.

 

The more prominent arm "southern" arm is very regular - emerging from the core on the south side and wrapping counterclockwise around the core to the north, unwinding gradually as it curves to the east and then pulls away from the central region more suddenly on the south side.  This arm is very patchy and delineated by a large number of HII knots with the two most prominent ones near the outer southern end.  The "northern" arm begins to emerge from north of the core, tightly wraps counterclockwise around the core, passing near or through a few superimposed stars on the south side of the core, unwinding more as it stretches again to the north.  The arm structure is a bit more complex on the north side due to side branches and the embedded HII knots are more scattered.

 

The HII regions were viewed more carefully at 610x.  The following identifications are from Paul Hodge's 1976 "HII regions in NGC 628" (ApJ, 205, 728), which lists over 700 HII knots.  The brightest is #627, near the end of the outer southern arm 2.7' SSW of center. It appeared fairly bright, fairly small, round, ~20" diameter.  Moving clockwise along this arm towards the core, the next prominent knot is #598 situated 2.2' SSE of center.  It was slightly fainter than #627, round, 15" diameter.  Next in line is #552, a faint round knot of 10" situated 1.8' SE of center.  East of the core by 1.5' is #406, a very faint, round 10" knot situated 36" S of a superimposed mag 14.5 star.  Just 30" W of this star and 1.2' NE of center is #292, a fairly faint, very small knot, ~8" diameter.  Continuing inward along this arm, the next knot is #196, a very faint hazy spot 1.3' N of center.  Finally, less than 1' NW of center is another very faint patch with multiple Hodge numbers #260-268.

 

There were no notable knots on the inner southern portion of the northern arm, but a noticeable clump of knots is on the NW portion of this arm.  First was #167/168, a faint 10" knot 1.6' NW of center.  Continuing outward 2.0' NNW of center is a faint, elongated patch, ~25" diameter, consisting of #91-95 and #49 at the north end of the glow.  I didn't search the outer region of the halo for additional HII knots, except noted #330, a 10" knot situated between two mag 12-13 stars at the eastern edge of halo, 3.9' from center.

 

24" (8/7/13): viewed type IIP SN 2013ej, discovered on July 25th, 92" E and 135" S of center.  It appeared bright at mag 12.5.

 

17.5" (2/2/02): viewed type Ic SN 2002ap, discovered just 3 days earlier on Jan 29th. The supernova was easily visible as a mag 12.5 "star", situated 4.6' W and 1.5' S of center.  This very energetic event is considered a hypernova, resulting from an extreme core-collapse scenario.

 

17.5" (8/31/86): bright, large, round, very bright core.  A spiral arm is attached at the east side of core winding towards the west along the south side.  A dark gap is visible between the arm and the main central portion.  Several stars are superimposed in the halo.

 

13.1" (8/24/84): very prominent, fairly small bright core surrounded by a very large, diffuse glow.  Visible in 16x80 finder.

 

8" (many dates from 10/4/80 to 8/24/84): very small bright core surrounded by a large faint halo. Fairly even surface brightness.

 

Pierre Méchain discovered M74 = NGC 628 = h142 in September 1780.  William Herschel made several observations of M74 with various telescopes and claimed to partially resolve it into a number of extremely faint stars.  With the 18.7" on 14 Oct 1784 (sweep 289): "easily resolvable; some stars visible in it, the coma extremely faint at the edges and not resolvable."  M74 is the only Messier galaxy that Herschel observed in the 40-foot telescope (48-inch mirror), though he didn't notice spiral structure under poor conditions on 28 Dec 1799: "Very bright in the middle, but the brightness confined to a very small part, and is not round; about the bright middle is a very faint nebulosity to a considerable extent. The bright part seems to be of resolvable kind, but my mirror has been injured by condensed vapours."  The same night he completed sweep 1092 with the 18.7".

 

John Herschel  called it "resolvable" and classified M74 as a globular cluster in the General Catalogue of 1864.  On 13 Dec 1848, Lord Rosse and/or assistant George Johnstone Stoney detected spiral structure with the 72" and noted "Rough sketch made. Spiral?"  The next night he "confirmed last night's observations; feel confident it is a spiral."  LdR listed M74 as "Spiral or curvilinear" in his 1850 paper.  Isaac Roberts photographed the spiral in September 1893.

17.5" (10/13/01): near Struve's position is a striking 1' chain of 5 stars mag 12.5-13.5 extended WSW-ENE.  Two of the stars at the following end of the chain form a very close pair.  There is also a wider trio of stars which follows by 6', but this is a courser, less interesting group in the field and less likely to fit Struve's description "3*+ neb".

 

Wilhelm Struve discovered NGC 629 = ∑ 2 = Au 16 in 1825 with the 9.6" Fraunhofer refractor at Dorpat.  Struve included this object in a list of 9 "Nebulae detectae" in an appendix to his main catalogue of double stars, published in 1827.  Auwers included "Struve 2" in his 1862 catalogue of new nebulae with the description "irregular nebula with 3 *."  Auwers was unable to find it, though, with the Königsberg Heliometer in February 1861.  About 6' west of Struve's position is a tight string of 5 stars within 1' and Harold Corwin identifies this asterism as NGC 629. The brightest mag 12.2 star has companions at 11" and 13".

John Herschel discovered NGC 643 = h2435 on 18 Sep 1835 and logged "eF, R, very gradually little brighter middle, 40"."

 

In 1957, Gerard de Vaucouleurs concluded (based on Mt Stromlo plates) that NGC 643 was an outlying cluster of the Small Magellanic Cloud and not a galaxy as listed in the 1932 Shapley-Ames Catalogue.  Eric Lindsay independently listed it as a new cluster (not making the connection initially with NGC 643) in his 1958 paper on SMC clusters and described it from a 30 minute ADH plate (South Africa) as "a conspicuous object, clearly recognizable as a cluster with 20-30 faint resolved stars.  The texture and distribution of the outlying stars suggest it is globular; otherwise it would have been classified as certainly open."  NGC 643 was deleted from de Vaucouleur's 1964 Reference Catalogue of Bright Galaxies and Alan Sandage's 1981 revision of the S-A Catalogue.  RNGC gives the type as 28 (cluster in the LMC) instead of 29 (cluster in the SMC).  NGC 2000.0 classifies it as a globular cluster.  NGC 643B = ESO 029-053 = PGC 6117 is misidentified as NGC 643 in the RC3 (letter designation from the RC1).

18" (10/19/06): superb view at 225x using a UHC filter.  The main bi-polar body was very bright, elongated ~SW-NE and dominated by two large, irregular knots at either end.  The SW knot is brighter and the brightest portion is more elongated in the direction of the minor axis.  Both knots are somewhat irregular in shape and brightness.  A faint star is just off the SW end. The two bright knots are attached with a fainter bridge of nebulosity. Extending off the north end is a large "arm" that sweeps around towards the west and a slightly less obvious counterpart is attached at the south end and sweeps towards the east.  The overall effect mimics a photograph of a barred spiral galaxy or perhaps a rotating sprinkler head with jets of water curving away.

 

17.5" (8/2/86): bright, fairly large, consists of two prominent irregular lobes with a darker center; the SW lobe is brighter with straight edges while the NE lobe has a slightly curved edge.  A mag 13.5 star is attached at the southern edge of the SW lobe.  Extending from the main body of this striking bipolar planetary is a large halo that contains two large outer arms or wings similar to a spiral galaxy!  The outer "arm" attached at the NE end is brighter and longer and curves to the west.  The southern extension is short, fainter and less defined.  The general features described above were clearly seen in my 13.1" at 166x using an OIII filter on 10/10/86.

 

13.1" (8/24/84): SW end is brighter while the NE end is slightly curved.  Boxy appearance with a dark center.

 

80mm (1/20/07): at 12.5x appears as a very faint, very small low surface brightness spot that blinks well using an OIII filter and increases significantly in contrast.  At 25x and OIII filter appears as a fairly faint, round knot with a fairly high surface brightness.

 

Pierre Méchain discovered M76 = NGC 650 = H. I-193 on 5 Sept 1780 with a 3" refractor.  Surprisingly, William Herschel made no observations prior to his sweeps and first encountered the planetary on 12 Nov 1787 (sweep 780) as "Two close together, their nebulosities run into each other; distance of their centers is 1 1/2 or 2'."  The second nebula was catalogued as H. I. 193 (later NGC 651), assuming it was a newly discovered object.

 

Observing on Lord Rosse's 72" on 5 Nov 1866, Sir Robert Ball described M76 in detail as a "new spiral": "remarkable object; a new spiral possessing details of interest.  Previous observation as to form confirmed with some further particulars well seen in single lens.  It consists principally of the two B knots which according to Herschel are the pair of double nebula, and third much fainter knot p the other two.  Form compared to a reaping hook.  Sketched by Lord Oxmantown.  The nebulosity terminates very suddenly on the s edge where there is a star, probably distinct from, through very close to the nebulosity.  A branch of nebulosity in the following direction was suspected by both observes preceding from between the two knots."

 

Sir William Huggins first observed a single emission line in the spectrum (a second was likely present) in 1865-66.  It was first photographed by Issac Roberts in 1891 and he suggested the appearance was probably due to a broad ring seen edge-on.  Based on a Crossley photograph, Curtis (1918) described, "central star of mag 16.  Quite irregular, but evidently to be included as one of the larger members of the planetary class.  The central and brighter portion of the nebula is an irregular, patchy oblong 87"x42" in pa 40° from the ends of which faint, irregular, ring-like wisps extend total length 157" in pa 128°.  Brightest patch at southern end of central part."

 

T.W. Webb's "Celestial Objects for Common Telescopes" (1881 or 1885 edition?) described it as a "Pearly white nebula, double; curious miniature of M27 and like it, gaseous, preceding a little the brighter. Earl of Rosse, spiral."  In the 1903 "Popular Astronomy" publication, an observing report is titled "The Miniature Dumb-bell Nebula, Messier 76."  Leland Copeland called it the "Little Dumbbell" in a Feb. 1960 Sky & Telescope article "An Amateur's Tour of Planetary Nebulae" .

In his main catalogue, he noted "Caroline Herschel [discovered it in ] 1783." and Dreyer credited Caroline with the discovery in the NGC.

 

Michael Hoskin supports this identification, but Wolfgang argues that Caroline more likely discovered nearby NGC 663, which is both larger and richer.

Caroline Herschel possibly discovered NGC 663 = H. VII-31 on 27 Sep 1783 with her comet-seeker reflector.  She found "a cluster of stars in the middle [of Delta and Epsilon Cass & Chi Per (Double Cluster)]."  Additional observations were made on 30 Oct 1783 and 9 Apr 1785.  In his main catalogue, though, William credited Caroline with the discovery of H. VIII-65 (later NGC 659).  But Wolfgang Steinicke argues in his book "William Herschel - discoverer of the Deep Sky" that NGC 663 is brighter and larger, so more likely to have been seen by Caroline.

 

William Herschel independently discovered NGC 663 on 3 Nov 1787 (sweep 774) and recorded "a beautiful cluster of pretty large stars near 15' diameter, considerably rich."  Neither John Herschel nor Lord Rosse's assistants observed the cluster and Dreyer credited William with the discovery in the NGC.

Heinrich d'Arrest found NGC 674 on 2 Dec 1861 with the 11-inch refractor at Copenhagen and noted "pretty bright, elongated, *14 follows by 8 seconds."  There is nothing at his position, but 2.0 min of RA east is NGC 697 and the description fits!  John Herschel and Dreyer assumed this was a new discovery and catalogued d'Arrest's object as GC 398 = NGC 674.  Curiously, he claims the object was found the same night (4th of 411) that he also observed NGC 697.  Father Hagen and Bigourdan searched fruitlessly for NGC 674 and Karl Reinmuth, in his 1926 survey based on Heidelberg plates, says "not found, = NGC 697?"  That conclusion is warranted.  See Corwin's notes.

William Herschel discovered NGC 676 = H.

John Herschel made two observations.  On 24 Sep 1830 (sweep 300) he wrote, "a *9m with a vF narrow ray of nebulosity; a most curious object."  The galaxy was observed four times at Birr Castle.  On 8 Nov 1876, Dreyer recorded "*9m with pF neb elongated 168.4°, longer on the side of *, concave preceding, convex following."

 

The bright superposed star is included in the CGCG magnitude (10.5z).  Steinicke notes that the separation from centre is only 9", the smallest value of all cases of bright superimposed stars in the NGC!

III-563, along with NGC 703/05/08, on 21 Sep 1786 (sweep 599).  He described the quartet as "Four, unequal, 3 in a row [NGC 704, 705, 708], the 4th [NGC 703] making a rectangle with them.  All in the space of 2 or 3'; the one at the angular part [NGC 708] is much larger than the others."

 

Birr Castle assistant R.J. Mitchell observed the group on 7 Oct 1855, noting "[NGC 704] is seen with higher power (single lens) to be double."  So, he resolved this double system.  I suggested to Harold Corwin (in Mar 2014) that the two components could justifiably be labeled NGC 704A and NGC 704B.

John Herschel probably observed the galaxy from the Cape and simply described "eeF; 40 arcsec".  Neither of the Herschel's positions are very accurate.  Christian Peters measured a more accurate position in 1881 that was used in the NGC.  Ormond Stone (I-43) probably independently discovered the galaxy in 1886, though his rough position is 1.5 tmin east and 5' north of PGC 7118.  Dreyer assumed this was a different object (there is nothing at Stone's position) and the galaxy was catalogued as NGC 757.  So NGC 731 = NGC 757, with NGC 731 the primary designation.

Bindon Blood Stoney discovered NGC 733 on 11 Oct 1850 (Friday).  Bindon may have been observing with his brother George Johnstone Stoney, who visited Birr Castle several weekends in Fall 1850.  The "nebula" was labeled Epsilon in a field sketch and an offset was measured of 115" in PA 293.3 deg (NW) from Alpha [NGC 736].  There is nothing at this exact position, though a mag 15 star is 97" from NGC 736 in PA 296 deg and Harold Corwin identifies NGC 733 with this star.

 

RNGC and PGC probably misidentify PGC 7255 as NGC 733.  This small elongated galaxy is located 3.6' NW from NGC 736.  The separation appears to be too large to be a match though the PA = 291d is coincidentally close and the galaxy was (barely) visible in my 17.5".

Francis Leavenworth discovered NGC 734 = LM 1-41 on 9 Nov 1885 with the 26" refractor at Leander McCormick Observatory and reported "mag 14.0, vS, R, brighter middle to a nucleus, *11 p[recedes] 11 sec."  His rough position (nearest minute of RA) happens to be just 3' N of PGC 7121, and this galaxy is identified as NGC 734 in the RNGC and PGC.  The 11th mag star in the description (also shown on his discovery sketch) might refer to a star situated 4.3' WNW (the difference in RA is 17 sec), though a brighter star even closer (3.2' SSE) is not shown on the sketch.  I proposed to Corwin and Wolfgang Steinicke that a better candidate for NGC 734 is 2MASX J01532872-1659442 = PGC 170023.  This galaxy is brighter than PGC 7121 and has a star 13 tsec due west.  PGC 170023 is further off in RA from Leavenworth's position than PGC 7121 but is a better match in declination, typical of the Leander McCormick positions.  Corwin agrees with my identification and is now incorporated in NED, but not HyperLeda.

Two faint companions are nearby, the trio forming V Zw 146.  LEDA 2045360 is 1.4' NW of center.  It appeared faint, round, 10" dia.  Easily visible due to a reasonably high surface brightness.  It is situated just 35" NNW of the mag 12 star to the NW of NGC 735.  PGC 7293 is 1.4' NE of NGC 735 and appeared extremely faint, round, 8" diameter. Only visible occasionally with averted.

 

17.5" (11/27/92): faint, small, very elongated 3:1 NW-SE.  The apparent elongation may be exaggerated due to a mag 14 star located at the NW edge 20" from center.  Several stars are nearby including a mag 10 star 1.5' SW and a mag 11.5 star 1.3' NW.  Located about 1° north of the NGC 750/751 group.

 

William Herschel discovered NGC 735 = H.

John Herschel observed NGC 736 on 3 sweeps. He described it on 11 Nov 1827 as "pB; R; bM; has a *13m np".  Both Herschel's positions are accurate and they missed the nearby edge-on NGC 740.  John Herschel thought his father's description was irreconcileable ("much elongated" vs "round"), so they probably referred to different objects and he assigned separate designations in the General Catalogue.  Bindon Stoney sketched the group using the 72" on 11 Oct 1850 and NGC 736 is labeled Alpha.

Bindon Blood Stoney, possibly accompanied by his brother George Johnstone, discovered NGC 737 on 11 Oct 1850 during an observation of the NGC 736 field.  The galaxy was labeled "Beta" on a constructed diagram.  He measured a distance of 30" in PA 12° from NGC 736.  At this offset is a mag 15 star.  The 9 Jan 1874 observation notes "[h169 = NGC 736] has a 12m star 11.9°, 35.1" distant, this must be beta of Oct 11 1850, when it was recorded as a nebula.  [Sir J. Herschel records 3 observations of this companion object, all taken in Nov 1827.  Nov 11 has *13 np, Nov 16 has a "* near it" and lastly, Nov 22 "has a S* or stellar neb to the n."

 

In "Publications of Lick Observatory (Vol II), Sherburne Burnham identified NGC 737 as a mag 15.5 star about 30" N of NGC 736.  He accurately measured the offset from NGC 736 as PA = 10°, distance 32".  Curtis concluded "Does not exist; is simply a faint star" based on Crossley reflector plates at Lick and Karl Reinmuth, in his 1926 survey based on Heidelberg plates, also writes "*14.7 0.7' N of N736, no neb...".

William Herschel discovered NGC 750 = H.

John Herschel described NGC 750/751 pair as "round" on one sweep and "elongated" on another, but neither Herschel was able to resolve the pair, perhaps as their magnification was too low.  Lord Rosse's assistant Bindon Stoney first resolved the pair on 11 Oct 1850.  Édouard Stephan also noted the two nuclei on 13 Oct 1869 at Marseilles Observatory.

Birr Castle assistant Bindon Blood Stoney discovered NGC 751 on 11 Oct 1850 (Friday).  Bindon's brother, George Johnstone, may have participated in the observation as he visited Birr Castle several weekends in Fall 1850. It was described as a "D neb [with NGC 750], Pos 171°, Dist 25", nf is a third nebula [NGC 761]."

 

On 10 Dec 1873, Ralph Copeland gave a more detailed description: "D neb; cB, pL, R, suddenly brighter in the middle and pF, S, R, suddenly brighter middle."  John Herschel's entry for GC 456 is confused; his description "nf h175 [NGC 750]" refers to NGC 761, but he used the same position as NGC 750 ("D neb"), so his comment could be interpreted as referring to NGC 751.  Perhaps to avoid confusion, Dreyer added the entry GC 5200 in the GC Supplement (with reference to the 1861 publication) for NGC 751 and used GC 456 for NGC 761 in the NGC.

Two equal mag companions to the south form an isosceles triangle.  There are no dense regions and the many brighter mag 9-10.5 stars are pretty evenly distributed throughout the field.  Many of the stars appear to be arrange in long strings and arcs, though.  There are perhaps 150 stars in the field (difficult to count) with a few nice pair and trios.  Off the SW side just out of the field is a wide bright pair of mag 5.7/5.9 stars at 3.6' (56 And).  The western of these two stars has a striking orange-red hue and the SE star has a mag 12 companion at 18" separation.

According to Wolfgang Steinicke, William Herschel discovered NGC 752 = H. VII-32 = h174 on 24 Aug 1783 with his 6.2-inch reflector.  He noted (a couple of months before starting his sweeps) "Cluster of stars near 56 Andromeda, very rich, Messier has it not."  He recorded a naked-eye sighting, along with several other groups of stars, on 29/30 Oct 1783 (Steinicke).

  He viewed it again with his 18.7" on sweep 599 (21 Sep 1786) and called it "a vL coarse scattered cluster of vL stars, irregularly round, very rich.  I suppose it takes up half a degree."  Later he noted "like a nebulous star to the naked eye."

 

Caroline Herschel independently discovered NGC 752 on 29 Sep 1783 with her 4.2-inch comet-seeker reflector and called it a "fine cluster of stars. Messier has it not."  She added it to her discovery list as #13.

 

Italian astronomer Giovanni Batista Hodierna perhaps made the original discovery around 1654, but his entry (Table 4, #4, "Near the Triangle") could refer to M33 instead.

The place not very accurate."  His position with respect to Alpha and Iota Tri, which bracket the "patch" in the log, is 1 minute of RA to the east and 3' to the south.  Wolfgang Steinicke mentions this observation in his book on Herschel's sweeps.

48" (11/1/13): very bright, very large, elongated at least 5:3 WNW-ESE, ~5.4'x3', sharply concentrated with a blazing core that increases to the center.  Contains two spiral arms, though dominated by a bright, long arm that attaches to the core on the east side, wraps counterclockwise to the north of the core and then extends in a fairly thin arch to the west.  The arm extends over 3' in length and ends at the northwest tip of the galaxy, ~2.5' from the center.  It contains 1 or 2 very faint HII knots.  A second low contrast arm begins at the south end of the core and spirals out clockwise to the east.  This arm is broader and does not have a sharply defined edge but was fairly easily visible.  The outer halo to the southeast of this arm has a very low surface brightness.  Forms an interacting pair with NGC 770 3.5' SSW.  PGC 212884 (8x the redshift) was easily picked up 5.8' SW and appeared fairly faint, small, round, 18" diameter.

 

24" (9/7/13): bright, very large, elongated 5:3 WNW-ESE, 4'x2.5'.  Strongly concentrated with a very bright oval core.  The halo is clearly asymmetric and more extensive on the NW side.  With careful viewing a long arm is visible at 200x extending from the central region towards the NW.  The arm is better separated from the main body at 450x and ends near NGC 772:[HK83] 57, a slightly brighter HII knot that appears as an extremely faint, "soft" star.

 

18" (12/3/05): bright, very large, elongated 4:3 WNW-ESE, roughly 4'x3'.  The halo is asymmetric and more extensive on the NW side with a very strong impression of a spiral arm attached on the north side and sweeping to the west (confirmed on image).  Forms a pair with much fainter NGC 770 3.5' SSW.

 

14.5" (12/17/20): at 182x; fairly bright and large, oval ~4:3 WNW-ESE, at least 3' major axis.  Strong concentration with a very bright core that increases to a stellar peak. There was an impression of an "enhancement" on the north side, but not a distinct arm.  Pair with NGC 770 3' SSW.

 

13.1" (11/5/83): bright, moderately large, slightly elongated, sharp concentration.  Forms a close pair with NGC 770 3.5' SSW. 

 

8" (10/4/80): fairly faint, fairly large, oval, bright core, two mag 11 stars to SE.

 

William Herschel discovered NGC 772 = H. I-112 = h181 on 29 Nov 1785 (sweep 481).  His description reads, "cB or vB, L, R, mbM, 3 or 4' dia, difficulty resolving.  In the most resolvable part a faint red colour perceivable."  Herschel described several globulars (and many double stars) as having a red colour, though a galaxy is unusual.

 

On 3 Nov 1855, Lord Rosse assistant R.J. Mitchell wrote "...One branch in particular strongly suspected as at A [in diagram] curved towards the * preceding."  This description refers to the northern spiral arm and star preceding (indicated on the diagram) is the HII region NGC 772:[HK83] 57, from Hodge & Kennicutt's "An Atlas of H II regions in 125 galaxies".  Dreyer also noted this HII region on a 9 Jan 1875 observation: "An eeF neb point was by glimpses seen by both observers in Pos 315° +/, Dist. 2' +/- from [GC] 463."

NGC 796 is a young, massive cluster and the most compact and dense cluster in the Magellanic tidal bridge structure.

 

John Herschel discovered NGC 796 = h2456 on 18 Sep 1835 and remarked "F, vS, R, has a *12m 25" distance at 45° np."  On a second sweep he recorded "somewhat doubtful, but I believe it is a vF neb involving a vF star."  His third observation was reported as "eF, S, R, 10" close to a vS star." 

 

This object was first identified as an outlying open cluster of the SMC in 1935, based on long exposure Bruce plates taken at the Arequipa station in Peru.

John Herschel discovered NGC 823 = h196 on 14 Oct 1830 and recorded "A vF double star enclosed in a vF neb."  Herschel also observed this nebula at the Cape (h2460) and gave the same description.  Lewis Swift apparently independently found this object on 8 Oct 1896.  Sw. 11-34 (later IC 1782) was described as "vF; D* of = mag in nebulosity.  Curious object."  He added the note "This appears like a nebulous double star, but I think it is simply a double star in a nebula.  There is a vast difference between a nebulous star, and a star in a nebula."  Dreyer must have missed the close match of Swift's and Herschel's position and their descriptions are virtually identical.  So, NGC 823 = IC 1782.  See Corwin's notes.

 

Joseph Turner sketched NGC 823 with the Great Melbourne Telescope on 11 Nov 1876 (plate I, figure 6 in "Observations of the Southern Nebulae..."), showing a brighter star at the east edge and a stellar nucleus, though he interpreted these as a "very small double star involved".

NGC 832 = NGC 1226?

03 11 05.4 +35 23 12; Per

 

See observing notes for NGC 1226.  Here's the description of the double star suggested by Harold Corwin as a candidate for NGC 832:

 

17.5" (11/1/97): faint double star mag 14/15 at 7" separation.  Difficult to resolve cleanly at 220x in mediocre seeing due to faintness of the north-northeast component.  Easier to resolve at 280x.  Although the identification as NGC 832 is not certain, this close double star could easily be mistaken as a small nebulous object.  Located 4.3' NE of a mag 9.5-10 star. Also 2' SW is a wider, brighter pair of mag 13.5-14 stars at 11" separation, which is much easier to resolve.

 

Heinrich d'Arrest discovered NGC 832 on 17 Sep 1865 with the 11-inch refractor at Copenhagen and noted (single observation) that a mag 9-10 star was 5' southwest.  There is nothing at his position and there is not a bright star 5' SW.  Corwin suggests this number may apply to a close double star (7" separation) at 02 11 00.8 +35 32 29.  This pair is 24 seconds following d'Arrest's position (similar dec) and has a mag 9-10 star 4.3' southwest.  RNGC misidentifies PGC 8280 as NGC 832.  This extremely faint galaxy is 6.6' W of d'Arrest's position and is certainly too faint to have been seen.

 

In an email on 26 Jul 2016, Harold Corwin found that if d'Arrest made a 1-hour transcription error in RA his position is a good match (about 1' too far north) with NGC 1226.  Furthermore, there is a mag 10.4 star 4.3' SW, matching d'Arrest's description.  This identification seems likely as d'Arrest made several similar 1-hour errors in RA: NGC 3167 (= NGC 2789), NGC 3575 (= NGC 3162), and NGC 3760 (= NGC 3301).

John Herschel noted it was the "third in order and in size."  Observing with the 48" Great Melbourne Telescope, Joseph Turner noted NGC 838 was "rather the brightest of the group", though the later observer Pietro Baracchi thought it was the faintest.

William Herschel discovered NGC 841 = H. III-604 = St. 13-16 on 17 Jan 1787 (sweep 692) and commented "vF, stellar, confirmed 240x."  His position (reduced by Caroline Herschel and Arthur Auwers) is just 4 seconds of RA west of UGC 1676. John Herschel mistakenly assumed his father's object was identical to his h204 (= NGC 845) and the end result was Dreyer equated NGC 845 = GC 501 = H. III-604 = h204. Heinrich d'Arrest observed the galaxy on 22 Sep 1865.  His RA was 13 seconds too large but he commented there was an error in the Herschel's positions (Auwer's reductions).

 

Probably based on d'Arrest's comments, Édouard Stephan observed NGC 841 on 24 Nov 1883 (he observed all 3 NGC galaxies here), as well as 5 Dec 1877, and reported it in his 13th discovery list (#16) at the correct position.  Dreyer assumed Stephan's object was new, so he was credited with the discovery of NGC 841 in the NGC instead of William Herschel. He also observed this galaxy among his last recorded observations on 22 Nov 1886.  Malcolm Thomson discussed the identifications in Q. Jl R. astr. Soc.

John Herschel discovered NGC 845 = h204 in Oct 1828 and logged "vF; irregular figure."  His position corresponds with UGC 1695 = PGC 8438.  Herschel and Heinrich d'Arrest equated H.

Édouard Stephan observed the galaxy on 1 Dec 1877 with the 31" silvered-glass reflector at Marseilles Observatory (added as an "anonymous" nebula in Esmiol's 1916 re-reduction of Stephan's positions), though didn't report it as new in any list.  See Corwin's notes.

William Herschel discovered NGC 863 = H. III-260 = h205 on 6 Jan 1785 (sweep 351) and noted "vF or eF, vS, stellar, not so faint as the last [NGC 850]".  There is nothing at his position, but 30 seconds of RA west and 3' north is UGC 1727.  John Herschel measured an accurate position on 24 Nov 1827 (sweep 108) and described it as "vF; R; bM."

 

On 3 Oct 1856, Lewis Swift recorded 3 galaxies: NGC 859, NGC 866 and NGC 868.  The second entry, which reads "pF; pS; R; little brighter middle; sf of 2", also fits UGC 1727, though Swift's RA was 70 seconds too large.  Then on 31 Oct 1886, Swift revisited the area and found NGC 885, described as "vF, vS, R, little brighter middle."  There is nothing at his position but Corwin suggests he may have made a 5 minuted error in RA in which case this would be another reobservation of NGC 863!  If so, then NGC 863 = NGC 866 = NGC 885, with NGC 863 the primary designation.

48" (10/29/16): this striking two-armed barred spiral appeared bright, fairly large, overall elongated 3:2 SW-NE, well concentrated with a bright core.  The core extends into a weakly defined bar WNW-ESE.  A long thin spiral arm is attached to the west end of the bar and it curled gradually counter-clockwise to the south for nearly 90°, ending due south of the core [separation 1.2'].  A bright mag 10.7 star is superimposed on the east side [44" ESE of center].  The second spiral arm was not as easily seen as it begins just inside (west) of the bright star, which detracted from the view.  This thin arm extended straight north, roughly at a right angle to the bar and merged into the halo on the northeast side.  UGC 1775 = Arp 10 is 49' SE.

 

24" (12/6/18): at 260x; fairly bright interesting galaxy with a mag 10.7 star superimposed on the east side that detracts from viewing structure.  Overall the galaxy is fairly large with an irregular halo roughly SW-NE, ~2.5'x1.8'.  Contains a very bright, round nucleus and the brighter central region appeared extended WNW-ESE.  A spiral arm on the west and south side appeared as a slightly enhanced "wing", mostly seen as an enhanced curving edge.  The opposing arm was only a short and weak arc enhancement that extended north of the bright star.

 

13.1" (9/3/86): fairly faint, oval SSW-NNE, even surface brightness.  A fairly bright mag 11 star is at the following edge 43" ESE of the center.

 

William Herschel discovered NGC 864 = H. III-457 = h206 on 25 Oct 1785 (sweep 464) and noted "vF, cL, very little brighter middle, milky, preceding a bright star and the nebulosity joining to it, but probably unconnected."  John Herschel logged on 25 Sep 1830 (sweep 300), "eF; R; attached to and np a * 11.12 mag.  Clouded before it could be fully verified."  Despite the clouds, his position and description match.

Lewis Swift found NGC 866 = Sw. 5-24 on 3 Oct 1886 and again on 31 Oct 1886 (NGC 885 = Sw. 5-27) with the 16" refractor at the Warner Observatory.  There is nothing at his position, and Herbert Howe reported he could not find NGC 866 in 1899-00.  Swift's discovery positions for NGC 866 and 885 are similar in declination but differ by 4 minutes in RA.

 

In the case of NGC 866, Swift's RA was 1 min of RA east of NGC 863 = UGC 1727, and NGC 885 is 5 min of RA east of NGC 863.  William Herschel (III-260) discovered this galaxy 100 years earlier and it was catalogued as NGC 863.  So, NGC 863 = NGC 866 = NGC 885.  There are several cases where Swift recorded two observations of the same galaxy in two different lists, including Sw. 5-23 = NGC 859 (3 Oct 1886) and Sw. 5-22 = NGC 856 (31 Oct 1886), which were found on the same two nights!

William Herschel discovered NGC 867 = H. III-2 on 21 Dec 1783 (the only nebula in his short sweep #61).  His complete description (in Dreyer's 1912 revision of Herschel's catalogues) reads "An almost invisible faint neb, it is R and about 8 or 10" diameter, being brighter in the centre than outwards.  It can only be seen when the glass if perfectly clean and the attention confined to the object."  Dreyer noted "By two diagrams it is about 1.5° nf a star which was taken to be 69 Ceti, but obs[ervation] was interrupted by clouds."  There is nothing at Herschel's rough position and Bigourdan was unable to recover H. III-2 on two attempts.

 

Heinrich d'Arrest suggested NGC 867 might be a duplicate of NGC 875 and Dreyer noted this in the NGC entry for 875, although Herschel's position is a poor match.  Corwin also suggests IC 225 as another possibility.  See his identification notes for more.

Lewis Swift discovered NGC 868 = Sw. 5-25 on 3 Oct 1886 with the 16" refractor at Warner Observatory.  His position is a good match with UGC 1748 = PGC 8659, although other galaxies found that night in the area have poor positions, which seems like an odd coincidence.  See Corwin's notes on NGC 859 and 863.

17.5" (10/25/97): this is the brighter and richer western member of the famous "double cluster". Includes a mag 6.6 star near the center and a mag 6.7 star 2.5' NNE.  Close following the mag 6.6 star is a neat parabolic group of five stars opening towards the star.  On the west side of this star is a rich group of ~20 stars mostly arranged in an incomplete ring.  A faint curving string of stars from the mag 6.7 star leads to the parabolic quintet.  The 20' field at 220x has too many stars to count, but probably has ~200 stars.

 

8": this is the western component of the "double cluster".  Very bright, large, about 30' diameter.  Very rich with about 100 stars resolved, includes several bright mag 6.5-7.0 stars in the center.  Forms a pair with NGC 884 at edge of 100x field.

 

Naked-eye (11/13/07): I noticed that the Double Cluster was clearly resolved into two "clumps" naked-eye.

 

Hipparchus catalogued the Double Cluster about 130 BC and Ptolemy copied it into his Almagest: "At the tip of the right hand [of Perseus] and nebulous [or misty]."  Giovanni Battista Hodierna first resolved the Double Cluster into stars by 1654.  He described "The third nebulous star, which is the first of all that Ptolemy invokes, [lies] in the constellation Perseus, at the tip of his right hand, below Cassiopeia.  [It is] very prominent amid the Milky Way, on account of a large profusion of stars, which are grouped in two places."

 

William Herschel viewed NGC 869 = H. VI-33 on 1 Nov 1788 (sweep 877). He recorded "A very beautiful brilliant cluster of large stars, very rich.  The place taken is the most compressed part of it, which is not in the middle; the middle of it contains a vacancy".  This was his first observation with the 18.7-inch, although he had observed it earlier through his 6.2-inch in August 1780.

William Herschel discovered NGC 883 = H. II-436 = h215, along with NGC 881, on 10 Sep 1785 (sweep 436) and logged "F, pS, lE."  On 8 Jan 1831 (sweep 318), John Herschel wrote "pB; R; gradually brighter in the middle; 15"; a coarse D* in field."

V = 4.6;  Size 30'

 

18" (8/11/10): NGC 884 includes three rare M-type red supergiants including two mag 8/8.5 colored stars separated by 1.9' on the NE side of the cluster appearing red and warm yellow (V403 and V439).  On the east side of the core of the cluster is the orange M-supergiant RS Per.

 

17.5" (10/25/97): the following group of the remarkable field of the "double cluster" is not as large or bright as NGC 869, but is centered around two wide triple stars.  The central 5' has up to 50 stars including a number of faint mag 14-15 stars forming a rich background.  Off the west end of the central region is a long string of stars which heads NE for 10' towards 3 brighter stars and then turning south and heading back past mag 8 orange-red RS Persei. The 20' field includes ~200 stars, although the cluster includes fewer bright stars as NGC 869 and is less compressed.

 

8": this is the eastern component of the "double cluster".  Very bright, large, very rich, ~20' diameter, ~60 stars, includes bright colored stars, many doubles.

 

Hipparchus catalogued the Double Cluster about 130 BC and Ptolemy copied it into his Almagest: "At the tip of the right hand [of Perseus] and nebulous [or misty]."  Giovanni Battista Hodierna first resolved the Double Cluster into stars by 1654.  He described (No. 3 of his 2nd table) "The third nebulous star, which is the first of all that Ptolemy invokes, [lies] in the constellation Perseus, at the tip of his right hand, below Cassiopeia.  [It is] very prominent amid the Milky Way, on account of a large profusion of stars, which are grouped in two places."

 

William Herschel logged NGC 884 = H. VI-34 on 1 Nov 1788 (sweep 877) as "A very beautiful, brilliant cluster of large stars irregularly round, very rich, near one-half degree in diameter."  John Herschel noted on 9 Dec 1831 (sweep 387) that "a fine ruby star in the centre".  The cluster was examined at Birr Castle looking for colored stars and five red stars were reported and one with a bluish tinge.

 

In William Denning's "Telescopic Work for Starlight Evenings", he noted it "In a telescope it forms a double cluster, and is one of the richest and most beautiful objects that the sky affords."  The earliest use may be in George Chamber's 1867 edition of Descriptive Astronomy"

48" (10/25/11): at 375x, the stunning edge-on NGC 891 was one of the top highlights of the observing week with the 48".  The galaxy nearly filled the 16' field, stretching nearly 12' by 2' SSW-NNE.  A 17th magnitude star is superimposed close to the NNE tip and a mag 16.5 star is near the SSW end.  The brighter, bulging central region extends 2.5' with a mag 12 star just north of the core on the west side.  A similar star is superimposed on the southern extension along with a few fainter stars.  A very high contrast dust lane slices through most of the galaxy except at the tips, where the galaxy fades out.  I was surprised how broad the dust lane appeared, particularly through the central section.  Although the dust lane perfectly bisects the galaxy into two symmetric halves, the edge of the lane was ragged and uneven.

 

A very small, dim galaxy was visible just off the east edge, 2.3' NNE of center and collinear with two mag 12 and 13.3 stars off the west edge of the galaxy.  It appeared as a very faint, elongated glow, ~15"x6".  Once identified I could hold this galaxy nearly continuously with averted vision.  In addition, an extremely compact anonymous galaxy is just 50" NW the center of NGC 891 and 40" SE of the mag 13.3 star.  It was visible continuously at 375x and 488x as a faint glow, roughly 6" diameter.  Surprisingly this object is not listed in NED, HyperLeda or SIMBAD, though it's probably no fainter than mag 16.5.

 

18" (8/26/06 and 11/13/07): the long, remarkable dust lane that bisects this galaxy was quite contrasty with a scalloped appearance along the edges.  Member of the NGC 891/1023 Group.

 

17.5" (8/31/86): bright, extremely large, edge-on 5:1 SSW-NNE, 10'x2'.  A striking dust lane bisects the galaxy and is most prominent through the bulging central region.

Subtle dust lane evident and pretty obvious in the central region.  A mag 12.8 star is superposed near the SSW end, 4.4' from center, and a mag 11.8 star is 1.4' N of center, at the west edge.

 

13.1" (7/16/82 and 9/11/82): at 140x; dust lane visible with averted.  Fairly easy using 166x.

William Herschel discovered NGC 891 = H. V-19 = h218 on 6 Oct 1783 (sweep 283) when the telescope was pointing off the meridian in the east so accurate positions could not be fixed.  He observed it again on 17 Oct 1786 (sweep 614) and logged "cB, about 15' long and 2 or 3' broad, bM, nearly in the meridian, a little from sp to nf."  A week later (sweep 621), he apparently had a better view and commented on the dark lane: "considerably bright, gradually brighter in the middle, about 15' l and 3' br, a black division in the middle in the direction of the length; at least 3 or 4' long."  He published a sketch with a distinct "black division" in his 1811 paper (Fig. 12) as an illustration of "nebulae that are remarkable for some particularity in figure or brightness."

 

In the notes section of his first catalogue, William mentioned that Caroline discovered this object on 27 Aug 1783, but this was a transcription error in the handwritten copy sent to the printer as she found V-18 (later NGC 205 = M110) on that date, though Messier had sketched it earlier.  Admiral William Smyth repeated this error in his Cycle of Celestial Objects (1844).  Herschel also found two members of nearby Abell Galaxy Cluster 347 (NGC 898 and 910) on 17 Oct 1786.

 

John Herschel remarked on 18 Sep 1828 (sweep 182): "has a chink or dark division in the middle and two stars."  He sketched the galaxy and remarked "An extraordinary object. Perhaps the figure is too nicely symmetrical as it certainly is too sharply defined.  It is of the last degree of faintness and may very well be though full in the field of view. There can hardly be a doubt a thin flat ring of enormous dimensions seen very obliquely."  The galaxy was also sketched at Birr Castle in 1850-51 and Dreyer noted, "I think the split is broader at one end, and that the nebula is a little more sharply defined on the following [Eastern] branch.  The central part is longer, but perhaps not so bright as on the preceding branch.  A bifurcation suspected at south end by Lord Rosse."

R.J. Mitchell discovered NGC 894 on 28 Nov 1856 using Lord Rosse's 72" and described a "D neb, components unite a preceding end.  The south one [NGC 895] is L, oval gradually brighter in the middle, the n one [NGC 894] is more elongated and fainter, also bM."  But the observation by J.L.E. Dreyer on 14 Oct 1876 revealed a single spiral with GC 530 = NGC 894 the brightest portion of a spiral arm: "pF, L, seemed first to have 2 Nuclei preceding-following, the foll one being the brighter, but it was soon seen that the preceding one is no Nucl, but only the brightest part of a curved arm, convex sp, very soft.  Sometimes I thought there was also some condensed part f the Nucl; Lord Rosse thought there was some patch or neby s of the nucleus [this probably refers to the southeastern spiral arm].  So, NGC 894 is the brightest part of the northwestern spiral arm of NGC 895.  This was recognized by Curtis after being photographed with the Crossley reflector at Lick Observatory (see 1918 Lick publication).

18" (10/13/07): NGC 896 and IC 1795 form a bright, detailed HII region at the NW corner of the huge IC 1805 HII ring ("Heart Nebula").  This complex is split into three or 4 distinct sections by dust lanes.  The largest section is IC 1795, which extends mostly north of the mag 10.3 star TYC 4050-2597-1for ~8'.  To the west of the mag 10 star is a  dust lane oriented NW-SE and beyond this lane to the west is a small, moderately high surface brightness patch (NGC 896) of 2' diameter.  To the east of the star is another broad dust lane extending N-S and following this lane is a fainter wash of nebulosity that streams to the north for over 15' in length.  It passes through mag 9 SAO 12287 and just north of this star the nebulosity has a small, brighter patch.  Initially, I thought the complex ended there on the NE side, but fainter nebulosity was noticed spreading out to the west for several arc minutes increasing the total size to 15'-20' for both N-S and E-W directions. 

 

17.5" (11/27/92): at 100x with OIII filter this is a fairly bright emission nebula, very large, about 20' diameter.  Elongated roughly E-W but consists of two distinct sections (NGC 896 and IC 1795) which merge together.  The bright western portion = NGC 896 has a high surface brightness, round, ~7' diameter and a star is off the NW edge.  A weak dark lane separates NGC 896 from faint IC 1795.  The region is weakly nebulous without filter.

 

William Herschel discovered NGC 896 = H. III-695 on 3 Nov 1787 (sweep 774) and recorded "eF, pL, iF.  Mem. The PD must be reckoned inaccurate, the string having been touched since the last cluster was taken."

 

NGC 896 is generally taken as the brightest portion of the IC 1795 complex on the southwest end (IC 1795/NGC 895 being the northwest portion of the huge "Heart Nebula").  John Herschel did not make an observation to confirm the position.  Corwin suggests that IC 1795 (found by Barnard) is a separate knot in the same HII complex, though Wolfgang Steinicke equates NGC 896 with IC 1795.

48" (10/27/19): at 375x; Showpiece two-armed spiral extending 5'x2' WSW-ESE and displaying a great deal of structure.  Contains a bright oval core with a very small, very bright nucleus. A knotty spiral arm is rooted at the northeast end of the core. It bends sharply to the west on the north side of the core and displays a blotchy surface. As this arm extended west it separated from an inner arm by a dark lane, spread out and faded at the west end.

 

A longer spiral arm emerges from the west side of the core.  It wraps tightly to the east in a bright arc to the south of the core.  This arm has a fairly well defined outer edge, but was not as splotchy as the northern arm.  At the east end, it splits into two arms with a slightly darker gap between and passes north of a mag 14.4 star.  The northern split arm has a brighter 15" patch at its tip [1.0' NNW of the mag 14.4 star].

UGC 1920 (listed as NGC 920 in all modern sources) appeared extremely faint, moderately large, ~1.5' diameter, very low surface brightness, required averted vision to glimpse.  This roundish unconcentrated glow is situated within a group of stars including a mag 11 star 1.6' WSW and mag 13 stars 1' NW and 1' SE.  I would not have noticed this object without averted vision and knowing the exact location using a printed finder chart.  Located 9.5' W of much brighter NGC 920 = IC 1799 and 15' WNW of NGC 933.

Lewis Swift discovered NGC 920 = Sw. 2-20, along with NGC 933,  on 11 Sep 1885.  His description reads "eF, eS, R; 1 or 2 eF * close; e diff." and his position is 16 seconds of RA west and 1.5' north of UGC 1920 = PGC 9377, the galaxy which has always been taken as NGC 920.  I wrote the following note in Jan 2014 to Harold Corwin and Wolfgang Steinicke after I realized that NGC 920 probably refers to IC 1799, a brighter galaxy 10' ENE:

 

"Swift's position in list II-20 is also 70 tsec due west of IC 1799 = UGC 1943, and an excellent match in declination (given Swift's general accuracy). So, IC 1799 is only off in RA from Swift's position. His description mentions "1 or 2 eF* nr", which could apply to either galaxy, but UGC 1920 also has brighter nearby stars that to me would be mentioned.  More importantly, though, IC 1799 is a more prominent galaxy than UGC 1920. In fact I probably would have missed UGC 1920 (the halo is very low surface brightness) in my 18-inch if I wasn't looking in the right place. IC 1799, on the other hand, was immediately noticed in the field, and has a much higher surface brightness. So, I'm suggesting NGC 920 = IC 1799 = UGC 1943."

 

Wolfgang Steinicke responded that his copy of Swift's paper came from Max Wolf's library in Heidelberg and "The '0' (of 20) is struck through and a '1' is noted to the right of the digit." Therefore Wolf also suspected a 1 minute error in Swift's RA.  Corwin notes that once 1 tmin of RA is added to Swift's RA, this leaves only a "difference in RA of only -10 seconds in RA and just -7 arcseconds in Dec -- negligible, in the face of Swift's usual errors."

 

Guillaume Bigourdan independently discovered this galaxy on 28 Jan 1891, measured an accurate position, and it was catalogued as Big. 251 (later IC 1799).  All major catalogues, as well as NED, HyperLeda and SIMBAD, identify this galaxy as IC 1799.  This leaves UGC 1920, the galaxy always assumed to be NGC 920, without a NGC or IC designation.

Ormond Stone discovered NGC 921 = LM 1-51 on 6 Jan 1886 with the 26" refractor at Leander McCormick Observatory.  There is nothing at his position but 1.3 min of RA east is MCG -03-07-015 = PGC 9287, and given the rough positions (nearest minute of RA), this is the likely object.  Herbert Howe measured an accurate position in 1898-99 using the 20" refractor at Chamberlin Observatory (repeated in the IC 2 notes).

Édouard Stephan discovered NGC 923 = St. 10-11 on 30 Oct 1878 (or earlier) and recorded "vF, S, R, weak concentration."

 

In March of 2020, Yann Pothier suggested the original discovery was made by Dreyer on 6 Nov 1874, though he assumed his observation applied to H. III-570 = NGC 898.  His description, which reads "pB (at least not vF), S, lE npp sff.  A * in Pos. 27.3°, Dist. 145.5".", does not apply to NGC 898, but NGC 923 instead, which is located 4.2 minutes of time following NGC 898.

 

Wolfgang Steinicke added the following comments: "The reason why Dreyer missed III 570 (NGC 898) on 6 Nov. 1874 is not due to an incorrect setting of the 72-inch. This is shown by correct data given for the other objects in that night (all observed before GC 533 [NGC 898]): GC 5036 (NGC 7794), GC 82 (NGC 169+IC 1559) and GC 272/78/89 (NGC 483/95/99). Dreyer simply had no coordinates. The main source of the Birr Castle astronomers were John Herschel's catalogues (h, GC). Unfortunately, Herschel could not find III 570 (and III 571 = NGC 910) in his sweeps, though both objects were in his working lists, based on Caroline's Zone Catalogue. Thus young Dreyer could only use WH's 2nd catalogue, giving relative positions to Beta Persei. Happy to see a "lE" nebula (at the place of NGC 923), he took the first choice: III 570 (NGC 898), though not at WH's place. For Dreyer derived no position for himself, he used WH's in his catalogues [and therefore later entered Stephan's observation to the NGC as a new object]."

24" (1/25/14): on this observation I used 375x and focused on the HII regions in the spiral arms of NGC 925.  [HK83] 120/121 was seen as an extremely faint, very small HII knot on the west end of NGC 925, 3.2' from center. This HII complex is near the western tip of the southern spiral arm, though I couldn't trace the arm itself as far this knot but a mag 14 star was identified 0.9' SSE.

 

[HK83] 44, a very faint 6" knot, was barely detached off the east end of the central bar.  A second fainter and even smaller knot, [HK83] 46/49, was occasionally seen ~20" WNW, right at the tip of the bar. [HK83] 42, a faint 6" knot, was seen along the weak southern arm, 1.5' SE of center.  The location was pinpointed just north of the midpoint of two mag 13.5/14.5 stars oriented E-W at 1.6' separation.

 

17.5" (11/26/94): fairly bright, large, about 5' diameter although the halo is irregular.  The core appears as a bright bar running through the center and elongated WNW-ESE with a fainter halo north and south of the bar. The bar is moderately concentrated and has a mottled texture.  There is a strong impression of very faint extensions or arms that begin to hook north on the WNW end and south on the ESE ends of the bar.  An extremely faint knot is just visible off the west side 3.3' from the center. This knot is an HII complex and association near the edge of a spiral arm and is catalogued as #120 in Hodge-Kennicutt's 1983 "An Atlas of H II regions in 125 galaxies".  Several stars are near; a mag 10.5 star lies 3.4' S of center, two mag 12 stars are just north of the core 1.0' and 1.5' from the center and a wide pair of mag 12.5 star are 5' W.  Member of the NGC 1023 Group.

 

14.5" (12/17/20): at 182x; fairly bright, large, elongated WNW-ESE with a very low surface brightness halo making it a wider oval, ~4.5' diameter.  A prominent bar runs through the major axis WNW-ESE, with a slightly brighter ncl at the center.  There was a strong suggestion of arm structure in the halo, particularly on the south side.  Several stars are superposed; the brightest three are mag 13-13.5.

 

8" (11/8/80): faint, fairly large, diffuse, irregular, elongated 2:1 NW-SE, even surface brightness.  A mag 10 star is 3.5' S.

 

William Herschel discovered NGC 925 = H.

= Not found, Gottlieb and Corwin.

 

Ralph Copeland, assitant to the 4th Earl of Rosse, discovered NGC 930 on 26 October 1872. While observing NGC 932 (GC 543) he noted a second object close nearby, which he described as "F, S, irregularly round, very gradually brighter middle" and offset from NGC 930 by 60" in PA 314.3 deg (NW) or 3.1" p and 42" N.  This nova was not mentioned in the subsequent three observations of NGC 930 in 1872, 1873 and 1876 but Dreyer added it to the GC Supplement (5238), repeating Copeland's description.

 

I carefully examined the POSS print of the field and the only object near the offset is a mag 12.4 star (GSC 1221-478).  There is a small reddish condensation with dimensions about 10" diameter at the northeast edge of the galaxy and Karl Reinmuth took this as NGC 930 ("eF, vS, R, very gradually very little brighter middle; 0.6' nf att NGC 932.").  But neither the separation nor the direction is a good match. So, NGC 930 is nonexistent.

 

The RNGC mixes up the identifications and lists the main galaxy as NGC 930 and calls NGC 932 non-existent.  Since Herschel was definitely the first to observe this galaxy, H. II-489 = GC 543 = NGC 932 should apply and the data listed in the RNGC under NGC 930 should be transferred to NGC 932.  UGC and CGCG equate the numbers NGC 930 = NGC 932, but the galaxy should be identified as NGC 932 only, since Copeland was clearly referring to something different.  Listed in RNGC Corrections #4.

24" (12/22/14): NGC 942 is the slightly brighter and southern component of a close double system with NGC 943.  At 375x it appeared moderately bright, small, slightly elongated, 0.4'x0.3'.  Well concentrated with a very small, very bright core and stellar nucleus.  NGC 943 is just 30" SSE (between centers) and within a common halo.

 

IC 230 (discovered by S.W. Burnham in 1891) lies 5.5' due west and appeared faint to fairly faint, small, round, 12"-15" diameter.  Easily seen despite a mag 15.7B.

Ralph Copeland, Lord Rosse's assistant, discovered NGC 942 = LM 1-53, along with NGC 943 on 31 Oct 1872.  He recorded a "Double in position 159.0°, distance of nuclei = 40".4; both are R; pretty suddenly brighter middle but the north preceding is slightly larger than the other.  Position of a 12m * from the brighter of the nebulae = 286.4°, distance = 139.3".  But he mistakenly assumed he was observing NGC 945.  As a result, Copeland's discovery went unnoticed until recovered by Yann Pothier in March 2020.  Édouard Stephan also found the pair (only a single position) on 29 Oct 1875, but never published the discovery.

 

Frank Muller rediscovered the pair in 1886 at the Leander McCormick Observatory and described both as a "nebulous double star?".  They were included in the observatory's first discovery paper (#53 and #54) with #53 (later NGC 942) placed 1' N of #54 (later NGC 943).  Herbert Howe measured accurate positions for the pair in 1897 using the 20" refractor at Chamberlin Observatory, as well as Sherburne Burnham (Publ of Lick Observatory, II).  Muller was credited with the discovery in the NGC.  RC 2 reverses the identifications (identifying NGC 942 as the northwestern galaxy), so the NGC designations go in RA order.

Ormond Stone perhaps discovered this galaxy a month earlier on 12 Oct 1886.  The nebula in Leander McCormick list I-56 is a close match with NGC 948, though there is no mention of brighter NGC 945, so I'm not certain of the identification.  NGC 945 and 948 were observed and measured by Sherburne Burnham (Publ of Lick Observatory, II) but his RA is too far west.  Herbert Howe measured accurate positions for the pair in 1897 using the 20" refractor at Chamberlin Observatory.

Édouard Stephan found NGC 952 = St. 3-6 on on 13 Oct 1869 and recorded a rough position 2' to the SE of NGC 940, discovered by d'Arrest in 1865.  Another observation on 24 Nov 1870 was 4' to the W.  He reported it as new in his third discovery list (#6) based on a micrometric position made on 14 Dec 1871, but there is nothing nearby and Bigourdan was unable to recover it.

 

Corwin concluded that Stephan must have misidentified his offset star (given as 4713 Lalande), though wasn't able to identify another candidate.  Emmanuel Esmiol, an assistant at Marseilles Observatory, reported in his 1916 re-reduction of Stephan's positions that the offset star was HD 15866 and he identifies the nebula as NGC 940.  In fact, Stephan's record book from 1886 notes his observation was a duplicate of d'Arrest's GC Supplement 5242 (= NGC 940), so he realized the equivalence before the NGC was published.

In the NGC notes, Dreyer mentioned this object was a possible "variable nebula" because it was easily seen by Schönfeld in 1863, 1864 and 1868, Friedrich August Winnecke and Heinrich d'Arrest, but was not found by Vogel in 1865 nor Schönfeld in 1861.  Sherburne Burnham (Publ of Lick Observatory, II) observed and measured the object without difficulty.  Winnecke wrote a paper in 1878 that claimed NGC 955 showed a "periodic variability".  It was also compared for variability on plates taken with the 60" at Mt Wilson in 1913 and 1917 and at the Helwan Observatory around 1920.  Wolfgang Steinicke covers the story in his book on the NGC (p519).

Ormond Stone discovered NGC 961 = LM 2-338 in 1886 with the 26" refractor at Leander McCormick Observatory and reported "1.5'x1.0', E 230°, *10 at end."  There is nothing at Stone's position but Harold Corwin found that if Stone made a 10 min (transcription?) error in RA, then NGC 961 is a duplicate of NGC 1051 = PGC 10172 (discovered by Édouard Stephan).  The declinations are similar and Stone's description applies perfectly to NGC 1051.  So NGC 961 = NGC 1051 = IC 249 (another duplicate observation by Javelle), with NGC 1051 the primary designation.  NGC 961 is classified as nonexistent in RNGC and NGC 961 is not included in the aliases of NGC 1051 in HyperLeda.

Francis Leavenworth discovered NGC 963 = LM 2-339 in 1886 with the 26-inch refractor at Leander McCormick Observatory.  There is nothing at his position but 1.3 min of RA east (a common error) is MCG -01-07-017 = PGC 9545.  Stephane Javelle independently discovered this galaxy (list 3-929) on 14 Dec 1903, measured an accurate position and Dreyer catalogued it again as IC 1808. So, NGC 963 = IC 1808, with discovery priority to Leavenworth.  RNGC appears to misidentify PGC 1066010 as NGC 963, though the position is 9' S of this galaxy.

Lewis Swift found this galaxy again on 22 Dec 1897 while observing from Echo Mountain in southern California, and recorded Sw. 11-40 as "pB; pS; vE."  His RA was 40 seconds too small and Swift and Dreyer didn't connect Sw. 11-40 with NGC 964, so it was catalogued again as IC 1814.  See Corwin's identification notes.

Forms a pair (similar redshift) with ESO 246-022 9' NE.  It appeared faint, fairly small, oval 4:3 or 3:2 NW-SE, ~30"x 18".  The surface brightness is low and nearly uniform.  Situated 1.6' NE of a mag 9.6 star.  LEDA 130202, 2.2' N, was not noticed (B = 16.5). The trio forms KTS 17, though the last galaxy is far in the background.

 

John Herschel discovered NGC 979 = h2486 on 22 Nov 1827 and logged "Not vF, S, R; almost stellar; between 2 stars nearly in the parallel."  His two observations differ by 7 sec in RA.

William Herschel discovered NGC 982 = H. III-573 = h236, along with NGC 980, on 17 Oct 1786 (sweep 614).  He described them together as "Two.  Both very faint, very small, easily resolvable, easily resolvable, distance 4', the place between them."  Since Herschel didn't measure individual offsets, Dreyer used John Herschel's positions for h235 and h236.  Unfortunately, JH measured the position of h236 accurately, but reversed the sign of the declination offset to NGC 982, placing it 5.5' too far south.  This resulted in h235 (later NGC 980) being placed SW of h236 (later NGC 982).  Dreyer copied these positions into the NGC, and noted the orientation as SW-NE, instead of NW-SE as they appear on the sky.

 

Because of this error, several catalogues (RNGC, CGCG, UGC and RC3) reverse the identifications of NGC 980 and 982, which should be NGC 980 = UGC 2063 = PGC 9831 and NGC 982 = UGC 2066 = PGC 9838.  MCG has the correct identifications.  This summary is based on Malcolm Thomson's Catalogue Corrections and Harold Corwin's NGC identification notes.

Édouard Stephan discovered NGC 983 = St. 3-11 on 13 Dec 1871 with the 31" reflector at the Marseilles Observatory.  His 6th magnitude reference star was misidentified, so the position in list 3, #11 (published in 1872) is incorrect. The error was caught and mentioned in a footnote in MN XXXII, although there was still a typo of 10 tmin in RA in the corrected position.  Using Stephan's offsets (3 minutes 8 seconds and 3' 38") from 15 Triangulum, his position corresponds with UGC 2133 = PGC 10034.  Stephan found the galaxy again 10 years later on 14 Dec 1881, measured an accurate position in St. 12-21, and Dreyer catalogued it as NGC 1002.  Karl Reinmuth missed the footnote in MN and in his 1926 survey based on Heidelberg plates, couldn't find NGC 983.  In any case, NGC 983 = NGC 1002.  Although NGC 983 should be the primary designation due to the earlier discovery, the galaxy is usually identified as NGC 1002.  RNGC misclassifies NGC 983 as nonexistent.  See Corwin's notes

48" (10/26/11): at 488x and 610x this disrupted galaxy (possible collisional ring) revealed its structure.  A very bright, sharp stellar nucleus is offset to the southwest side of the halo.  The moderately large halo appears as a 0.9'x0.7' oval or a circle that was squashed along the south and southeast edge, near the nucleus.  With averted vision, the brighter rim was noticeable and the galaxy appeared as a ring with a darker center and a "diamond" (the Seyfert nucleus) attached on the southeast side.  The ring appeared similar to a faint annular planetary.  An extremely faint mag 18 star is at the north edge of the rim.

 

2MASX J02343785-0853042, an easily visible galaxy, lies 6' S.  It appeared faint to fairly faint, slightly elongated NW-SE, 20"x15", broad concentration, brighter core.  A mag 12.5 star lies 45" NW.

 

17.5" (10/29/94): fairly faint, very small, round, 15" diameter, sharp stellar nucleus with a small very faint halo!  A triangle of mag 10/11 stars with sides 1.7', 2.5' and 3.0' is about 5' WNW and the galaxy forms the bottom of a "cross" asterism with these stars.  This is a Seyfert galaxy, accounting for the dominant nucleus.

James Dunlop discovered NGC 986 = D 519 = h2487 on 5 Aug 1826 with his 9" reflector at Parramatta (near Sydney) and described "a faint nebula, of an irregular round figure, about 30" diameter, north of a bright small star."  His single position is 9' SE of NGC 986 (typical error) and there are no other nearby brighter galaxies that he might have been picked up instead.

 

John Herschel described the galaxy on 23 Oct 1835 as "pB, L, pretty suddenly brighter middle, 3' long 2' broad, either binuclear or more elongated on the n.f. side than on the opposite."  On a later sweep he logged "B, L, pmE, very suddenly much brighter middle, 100" long 60" broad, unequally bright, and exhibiting an approach to binuclear form."  See Plate VI, figure 14 of the CGH Observations.  Herschel's secondary nucleus appears to be the brighter southwest end of the central bar.

 

Joseph Turner sketched the galaxy on 29 Nov 1875 with the 48" Great Melbourne Telescope.  He resolved it as a stretched S-shaped barred spiral (Plate I, figure 8 in "Observations of Southern Nebulae made with the Great Melbourne Telescope 1869 - 1885".  Albert Le Sueur earlier made a sketch (unpublished plate VII, figure 80).

Stephan's position is wrong, being taken from Baily's Lalande, where the places of two stars (with an 18 second difference in right ascension) are mixed up. I took the northeastern star, as I was not certain that it was not nebulous, while the southwestern one was certainly free from haze".  Emmanuel Esmiol deleted NGC 988 in his 1916 re-reduction of Stephan's measurements.

24" (12/28/16): at 375x; very faint to faint, small, round, 18" diameter, very low surface brightness.  Forms a close pair with NGC 997 1.8' SSW.

 

17.5" (10/8/94): extremely faint, very small, round, 20" diameter.  Very low even surface brightness and requires averted vision.  Forms a close pair with brighter NGC 997 1.8' SSW.

 

Albert Marth discovered NGC 998 = m 65 (along with NGC 997) on 10 Nov 1863 with Lassell's 48" on Malta and simply noted "vF".  NGC 998 was placed 2 sec of RA following and 1' N of NGC 997, and at this position is PGC 9934.

 

CGCG misidentifies NGC 997 with CGCG 414-028 = PGC 2802440, a small, very faint galaxy situated 8.2' NNE of NGC 997.  The UGC notes to NGC 997 and the RNGC follow the CGCG error and also misidentify CGCG 414-028 as NGC 998.  NGC 998 is mentioned as an anonymous companion to NGC 997 in the UGC notes.  PGC has the correct identification, though is incorrect to use CGCG 414-028 as an alias.  MCG reverses the identifications as well as the declinations.  The identification of NGC 997 is included in my RNGC Corrections #7.

18" (12/18/06): faint, small, round, 25" diameter, weak concentration.  Sandwiched between a mag 11 star 1' NE and a mag 14 star just off the SW edge [28" from the center].  Located just 2' NE of NGC 996 in the NGC 995-1005 group with NGC 1001 4.5' E.

 

17.5" (11/1/86): very faint, very small, round.  A mag 12 star is 1.0' NE.  Member of the NGC 995-1005 group with NGC 1001 4.7' E.

 

Édouard Stephan discovered NGC 999 = St. 3-14, along with NGC 996, NGC 1001 and UGC 2111, on 10 Nov 1871.  His published micrometric position was made the following month on 8 Dec 1871.  NGC 999 is the third in a group of 6 NGC galaxies discovered by Stephan.

 

CGCG, UGC, PGC and HyperLEDA incorrectly equate NGC 999 and IC 240.  Bigourdan measured IC 240 with respect to NGC 999 so they cannot be equivalent.  Malcolm Thomson noted this error in his survey of IC identifications and Harold Corwin suggests IC 240 is probably a line of 4 faint stars.
