48" (10/24/14): We had a superb view of NGC 7008 unfiltered at 488x and 610x. This irregular, annular planetary extended ~1.5'x1.2' SSW-NNE with a roughly oval outline, except on the SW end. Several stars are involved or just off the edge, including HJ 1606 = 9.6/11.7 at 19" separation, which is just off the SSE edge.
A very bright, elongated knot is at the NNE edge of the rim.
A larger elongated knot is just on its inside (towards the central star), with
the pair of close knots virtually attached. On the opposite SSW end is
the next brightest region, extending nearly 45° along the rim. This larger glow spreads irregularly
into the darker center and dims.
Another brighter knot is on the WNW edge of the rim (probably
A mag 13.5 star sits in the center of the darker interior with the central "hole" darkest immediately east of the central star. Another darker region is in the SE quadrant just north of HJ 1606.
18" (9/10/07): The "Fetus Nebula" is a fascinating annular planetary, best viewed at high power. Using 452x the oval halo is elongated SSW-NNE, ~85"x65". The most striking feature is a bright, 25" knot on the NNE end that is irregular in surface brightness with a very small brighter condensation near its south end. The SW quadrant of the planetary is also brighter in an elongated region and weakest on the E and SE edge facing the wide double star off the south edge.
In the darker center, a mag 13.5 central star is visible and a second fainter mag 14 star is near the NE edge. Also a mag 14 star is just off the west edge. NGC 7008 is situated just north of HJ 1606, a mag 9.3/10.2 pair at 18" oriented N-S.
17.5" (6/28/00): this beautiful, highly structured PN is situated just north of a wide double star (9.2/10.5 at 18"). At 280x, the annular oval is elongated SSW-NNE, ~90"x65". A bright 30" irregular knot is prominent at the NE end. The SW end of the major axis has a fainter condensation and the rim is clearly dimmest near the double star. The mag 14 central star shines steadily as does a slightly fainter mag 14.5 on the NE edge. Just off the west edge is another 14th magnitude star. The darker center is faintly luminous and the surface brightness is irregular over the entire oval giving a mottled, wispy appearance.
13.1" (9/11/82): bright planetary with unusual structure and several stars involved. The striking complete annular ring is elongated SW-NE. A mag 14 central star mag is visible, as well as a mag 14 star at the NE edge and a faint star off the W edge. A small brighter knot marks the NE end. The planetary is located just north of double star HJ 1606 = 9.3/10.5 at 18".
8" (8/16/82): unusual structure, curves and extends further south on the west side. A faint star is embedded.
80mm (9/10/07): the planetary was faintly visible in the finder at 25x using an OIII filter.
William Herschel discovered NGC 7008 = H. I-192 = h2099 on 14 Oct 1787 (sweep 765). He recorded "considerably bright, strong nebulosity of an irregular square figure. Seems to contain faint large stars, about 3' l and 2 1/2' broad." He observed it again the next night (sweep 767) as well as the 16th (sweep 768): "the stars which are visible in it, do not seem to belong to it."
On sweep 211, John Herschel logged "large; elongated; resolvable; has an appearance of two nuclei or points of greatest condensation; it touches a fine double star [h1606 = 9.3/10.2 at 18"]." Birr Castle assistant R.J. Mitchell viewed it on 19 Aug 1855: "seen as in sketch [1861 Monograph, Plate XXX, fig. 37]. 3 st in it, F neby reaches nearly up to the star sf; B knots in it, the nf one seems triangular in shape and sometimes I thought it split up by a dark line from sf to np."
Sir William Huggins first observed a single emission line in the spectrum in 1865. Francis Pease photographed NGC 7008 in 1914 with the Mt. Wilson 60" and described "the strongest bits of nebulosity are two condensations just E of the N end of the major axis. On the southeast side the eliipitcal forms seems eaten away, but traces of nebulosity may be seen connecting with a stars which lies [53" separation in p.a. 156°]. Based on Crossley photographs taken at Lick, Heber Curtis (1918) reported "irregular ring structure indicated; the dimensions are 86"x69" in p.a. 20°. The two brightest patches are at the north, and three stars lie in roughly circular gaps in the nebulosity must either be physically connected with the nebula or, if nearer to us, be surrounded by absorbing atmospheres."
In a 2001 issue of Amateur Astronomy magazine, Eric Honeycutt called NGC 7008 the "Fetus Nebula" due to its appearance in his 22-inch telescope.

48" (10/29/16): the remarkable Saturn Nebula was viewed at 1084x. The intense, inner "ring" is very elongated (~25"x10") with an unusual warped appearance. The inner ring is brighter on the west end. The rounder shell extends ~30"x25", slightly elongated WSW-ENE and contains an obvious "knot" on the north side of the shell. The ansae or FLIERS at the end of the jets varied in size and orientation, with the western one larger, brighter and angled outward on the north end. The central star was easily visible.
48" (10/24/14): at 610x; the western ansa (handle) at the end of the jet appeared as a small, narrow bar, roughly perpendicular to the extension, but slightly tilted, so the north end was pointing outward (west). The eastern ansa was much smaller but with careful viewing was slightly elongated and tilted in a mirrored orientation. Also, a very small, low contrast knot was noted on the north end of the outer shell. Otherwise, the details mentioned in the observation from last November were all noted.
48" (11/1/13): the double-shell structure was fascinating at 813x. The bright, inner ring was surprisingly elongated WSW-ENE, ~30"x10", with an irregular surface brightness and uneven thickness. The inner darker hole was also elongated, extending nearly the length of the nebula and was punctuated by a fairly easy central star. This annulus is encased in a rounder, outer shell, ~30"x25" diameter, with a slightly irregular rim (brighter at the north edge). Extending from the main body were the two easily visible "jets" extending WSW-ENE with prominent FLIERS or "ansae" (handles) at each tip [separation 44"] with the western tip slightly brighter. The color was generally greenish, though the outer halo had a salmon-colored tinge.
24" (7/24/14): viewed at 1000x in good seeing at Lassen National Park (elevation 8200 ft). The intense, inner annulus is 30"x18" with a bright, moderately thick green rim and darker center. The central star was nearly visible steadily within the darker center. The oval annulus was slightly irregular in surface brightness. It was surrounded by a rounder, fainter envelope, which varied slightly in brightness, particularly on the north side, which contained a noticeable knot. The fairly narrow jets were readily visible, though brighter on the west side. An obvious knot ("ansa") that was slightly elongated was visible at the tip of the western jet. The eastern extension only had a weak brightening at the tip.
18" (7/28/03): Viewed at 1087x in very good seeing. The 30" brighter inner oval is elongated WSW-ENE and has a noticeable irregular surface brightness (first time this was noted) with a brighter, thick rim and darker center (partially annular). Surrounding the high surface oval is a fainter, outer shell although interestingly, the transition appeared more gradual than at lower power. The extensions or jets were easily visible with very small knots ("ansae") occasionally visible at the tips.
17.5" (many dates 9/14/85 to 8/10/91): extremely bright, fairly small, very high surface brightness, blue-green color, about 30" diameter to the main oval body. At 412x, the two famous extensions or "jets" were easily visible extending WSW-ENE from the oval disc using direct vision. The western extension is brighter and a very small knot (ansae) is visible at moments with concentration at the tip of the west extension. A faint outer shell surrounds the bright disc.
13.1" (9/3/83): similar view to 17.5", but the eastern extension was more difficult to view.
13.1" (7/16/82 and 8/16/82): both ansae were definite at 280x as faint extensions though the western ansa was easier to see. A thin fainter shell encases the main body.
8" (10/31/81): bright, small, blue-green, high surface brightness. Rays extending outward are suspected, particularly on the western side in excellent seeing at 200x.
William Herschel discovered NGC 7009 = H. IV-1 = h2098 on 7 Sep 1782 at Datchet with his 6.2-inch reflector. During his third review of Flamsteed stars and double star survey, he described "a curious nebula, or what else to call it I do not know. It is of a shape somewhat oval, nearly circular, and with this power [460] appears to be about 10 or 15" diameter. It is of the same shape with 278 but much less in appearance. With 932 it is still the same shape but much larger. So that its appearance seems to follow the law of magnifying, from whence it is clear that it is of some real magnitude in the heavens and not a glare of light. The brightness in all the powers does not differ so much as if it were of a planetary nature but seems to be of the starry kind, tho' no star is visible with any power. It is all over of nearly the same brightness. The compound eyepiece will not distinguish it from a fixt star, at least not sensibly".
Wolfgang Steinicke states that Herschel recorded it five
more times with his 6.2" during his review period and 6 times during his
sweeps with the 18.7". On 2
Aug 1788 (sweep 851) he wrote, "The planetary nebula, considerably oval,
in the direction of the parallel nearly.
Of a bluish light, but not very well defined." This was a unique instance of recording
a color in a planetary.
Although Herschel is often credited with first coining the
phrase "planetary nebula", some credit should go to Antoine
Darquier's description of
Wilhelm Struve independently found NGC 7009 (∑ 8) in 1825 or 1826 with the 9.6-inch Great Dorpat refractor. It was included in his list of 9 "Nebulae dectae" in an appendix to his main catalogue of double stars. Auwers and d'Arrest measured accurate positions. Lord Rosse, Romney Robinson and George Johnstone Stoney observed the planetary on 23 Oct 1848 resulting in a sketch (Stoney's first observation and sketch) and description, "we have not detected any perforation, but it has ansae, which probably indicate a surrounding nebulous ring seen edgeways". (Fig 14, 1850 paper).
Stoney made another observation on 16 Aug 1849 and measured the "position of ring taken with an eyepiece furnished with a level and a position circle. Inclination of ring to horizon 9°." Although the nickname "Saturn Nebula" was not mentioned in Robinson's report to the Royal Irish Academy, the description in the 1880 publication (given as 16 Sep 1849) states, "Saturn neb. Pos of ring 81 deg".
Using a 9.5" refractor in 1856, Father Secchi sketched NGC 7009 and noted the nebula was fainter at the ends of the major axis and brighter along the north and south sides (AN 43, 157).
In 1867 Lassell reported his "Observations with the Four-foot Equatoreal at Malta" and his description from 23 Aug 1862 begins "My first impression of this Nebula was that it was a sky-blue likeness of Saturn". In a letter dated 26 Sep 1862, he goes into much more detail: In directing my large equatoreal upon the well-known planetary nebula situated in AR 20h 56m N.P.D. 101° 56' (1862), it has revealed so marvellous a conformation of this object that I cannot forbear to send you a drawing of it [see www.docdb.net/history/texts/display.php?article=1863rsps___12__269l], with some description of its appearance. With comparatively low powers, e.g. 231and 285, it appears at first sight as a vividly light-blue elliptic nebula, with a slight prolongation of the nebula, or a very faint star, at or near the ends of the transverse axis. In this aspect the nebula resembles in form the planet Saturn when the ring is seen nearly edgewise. Attentively viewing it with higher powers, magnifying respectively 760, 1060, and 1480 times, and under the most favourable circumstances which have presented themselves, I have discovered within the nebula a brilliant elliptic ring, extremely well defined, and apparently having no connexion with the surrounding nebula, which indeed has the appearance of a gaseous or gauze-like envelope, scarcely interfering with the sharpness of the ring, and only diminishing somewhat its brightness. This nebulous envelope extends a little further from the ends of the conjugate than from the ends of the transverse axis; indeed, it is but very faintly prolonged, and only just traceable towards the preceding and following stars....
Lassell's sketch shows the two ansae or handles as faint stars but the outer halo does not extend as far as the ansae. Hermann Vogel produced an excellent sketch on 20 Sep 1883 using the 27" refractor at Vienna. Besides the prominent inner elliptical ring and an oval darker central hole, the outer halo extends ENE-WSW and tapers on the ends with a star-like knot on the WSW end.
William Huggins first identified the emission line spectrum in 1864 (three lines were noted), along with several other planetaries. It was confirmed in 1868 by Lieutenant John Herschel, son of John Herschel, in an early spectroscopic investigation of southern nebulae while he was stationed in Bangalore, India.

Both knots are lively or mottled and slightly tapered in shape. They both contain stellar or quasi-stellar points near their centers with the western nucleus slightly easier. The eastern lobe is barely larger and brighter. The lobes are nearly tangent [6" apart between centers] but just separated by a darker lane and both lobes are encased in a common halo. At 807x, the two lobes were clearly separated by a dark lane (the Cheeseburger's "patty"!) oriented SSW to NNE. A central star was not seen. A mag 10.5 star is off the NE side, less than 30" from the center. Located 13' NNW of the mag 4.6 star 63 Cygni.

The double-lobed structure was clearly visible with the western lobe slightly elongated N-S and containing a brighter center. The eastern knot also has a quasi-stellar center at moments using direct vision and the knot has an irregular outline. Using the UHC, the lobes were more cleanly separated and the small fainter halo that encases the two bright lobes as more obvious. A mag 11 star is just 0.5' NE of center.

Sherburne Burnham discovered NGC 7026 on 6 Jul 1873 with his personal 6-inch Clark refractor at his home in Chicago (Memoirs of the RAS, Vol 44, p295). It was described in his "Third Catalogue of Double Stars" (1873) as "a very remarkable and curious double, or elongated planetary (?) nebula. It is close to a 9.3m star. This may have been noted before, but it is not in Herschel's General Catalogue, or Lassell's Catalogue of New Nebulae." It was also included in his 1879 "Double Star Observations made in 1877-8 at Chicago with the 18 1/2-inch Refractor of the Dearborn Observatory, comprising: I. A Catalogue of 251 New Double Stars with Measures; II. Micrometrical Measures of 500 Double Stars." He noted the "distance between nuclei as 2.57". Dreyer missed Burnham's two discovery notes, so NGC 7026 wasn't added to the General Catalog Supplement.
Ralph Copeland independently found this planetary on 18 Nov 1880 using a visual spectroscopic sweep and announced "a new planetary nebula has been found by Dr. Copeland at Dunecht, using Prof. Pickering's method of search." Burnham caught Copeland's "discovery" note and claimed priority in another 1881 article ("The planetary nebula in Cygnus"). Burnham later studied NGC 7026 with the 36" Lick refractor.
In 1909, Rev. Thomas Espin wrote (1909MNRAS..70..184E), "This autumn I have observed the nebula on several occasions. It consists of two elongated masses running N and small, each of which has a nucleus. To my eye the preceding nucleus is slightly brighter, and I have estimated them as 11.2, 11.4 mag, respectively. On Nov. 15 it seemed to me that the south part of the nebula ends more abruptly than the north. On the same night a faint star was suspected at the south end, and attempts were made to measure it. On all occasions the space between the two masses has seemed filled with nebulosity, and the object has appeared as one nebula with two nuclei."
Based on Crossley photographs taken at Lick, Heber Curtis (1918) reported "very irregular; there are two bright lobes 5" long in the shorter exposures symmetrically placed with regard to the central star, and about 6" apart from center to center. A bridge of nebulosity connects these and involves the central star, so that it resembles the letter H. Irregular wisps extend from each end of this formation, making the total length about 25" in p.a. about 10°.
Jay McNeil coined the nickname "Cheeseburger Nebula" in 1994 with a 10" f/5 Cave reflector. "It very much so reminded me of a small, nebulous hamburger with two perfectly shaped "buns" separated by a long thin dark lane (the meat ;-)."

V = 8.5; Size 18"x11"
48" (10/24/14): this fairly small, ultra-high surface brightness green planetary was observed at 610x. Overall, the object extends ~18"x12" NW-SE, but split up into three distinct components. The first and brightest component is an elongated glow (~10"x6" NW-SE) on the northwest side, which contains a very small, intensely bright knot at its western edge! The second bright component is adjacent to its east and is separated by a thin, darker lane. This section has an elongated, irregular outline (~10"x6" NW-SE), and is slightly mottled with brighter spots. A thin, high-contrast dark lane runs WSW-ENE at the south edge of these two sections. The third bright component, just southeast of this lane, appeared as an irregular, elongated bar, running 2:1 WSW-ENE, ~12"x6" and formed a "cap" on the southeast side. The two ends of this cap are very slightly curved (concave to the northwest).
18" (9/10/07): at 175x; appears as a small, very high surface brightness oval with a blue-green color. At 450x, this planetary is elongated 3:2 NW-SE, ~18"x12" and has an unusual bipolar appearance with two lobes. The 10" NW component has a very high surface brightness and contains a quasi-stellar brighter knot on its west edge. A fainter lobe juts out towards the SE and is slightly smaller (~8"). At 565x the SE lobe seems incomplete as if it was partially obscured and the two lobes are encased in a thin outer envelope. The view was fascinating at 807x with the sense of peering at a 3-dimensional object - the brighter NW lobe being closer and the partially overlapped SE lobe extending away in space. At this power both lobes were clearly irregular in shape and surface brightness.
17.5" (10/2/99): At 100x, the small greenish disc is very prominent but at higher powers appears bluish. Easily takes very high power and the view unfiltered at 380x and 500x was striking. Appears elongated 3:2 NW-SE, 0.3'x0.2', with two distinct lobes. The NW knot is slightly brighter and at times a stellar spot or star appears embedded at its SW tip. At 500x, the two knots are encased in a very small common halo that extends further out on the north side. The southern edge of both knots has a sharp, flat appearance.
13.1" (9/11/82): at 288x; small, bright, unusually high surface brightness, elongated NW-SE. There are two distinct overlapping nuclei and a narrow dark lane possibly separates these two condensations.
80mm (9/10/07): visible as a mag 8.5-9 "star" at 12.5x in the 80mm finder and easily identified using an OIII blink.
Édouard Stephan discovered NGC 7027 = St. 9-27 on 18 Sep 1878 with the 31-inch Foucault reflector at the Marseilles observatory. This planetary is probably the brightest object he discovered. From some reason it wasn't included in Esmiol's 1916 re-reduction of Stephan's positions.
The following observational history is from Wolfgang Steinicke. The Reverend Thomas Webb independently rediscovered NGC 7027 on 14 Nov 1879 using his 9.4-inch With reflector. He described it as an "object like a bluish 9 mag star, not quite of stellar character - a small pair, too close to be separated?" At higher magnifications it was seen as "bright, very ill-defined, nebulous disk of about 4" diameter, surrounded probably by a little glow, and much resembling the planet Uranus." Webb's announcement in several publications created a flurry of interest in late 1879 with spectroscopic observations by Knott, Copeland, Winnecke, Vogel. In 1880, Dreyer noted Stephan's prior discovery, though it was still commonly assumed that Webb was the discoverer. E.E. Barnard observed NGC 7027 in June of 1889 with the Lick 36-inch at 500x (with Burnham) and logged, "In the preceding part there is a small bluish -green star like object - shining through ? haze. Occasionally a darkish space separates the condensations into two."
Based on Crossley photographs taken at Lick, Heber Curtis (1918) reported "the condensations are not stellar in the shortest exposures. Quite irregular and roughly trinuclear, though the southern condensation is apparently two masses close together. The southern condensation and the brighter at the north are 7.5" apart in p.a. 135°."

ESO 530-018 is an extremely faint and small object in the NGC 7035 group. Located 8' ESE of NGC 7035 and 4' W of the ESO 530-020 triplet. It required concentration and extended viewing to glimpse this threshold object close (NE) of a mag 15 star. Confusing the observation further is a second threshold galaxy (MCG +05-50-004) that was also glimpsed on a couple of occasions close southeast of the star.
Frank Muller discovered NGC 7035 = LM 2-460 in 1886 with the
26" refractor at the Leander McCormick Observatory. His rough position (nearest minute of
RA) is 21h 11m -23d 05' and he only noted "iR" with a size of
0.5'. ESO/Uppsala and Harold
Corwin identify
The RNGC identifies either edge-on ESO 530-018 or nearby MCG -04-50-004 as NGC 7035. This pair lies 5' to 6' south of Muller's position, though happen to match in RA. As the Leander McCormick positions tend to be fairly accurate in declination, this identification is less likely. It is also possible that NGC 7035 refers to a close chain of three galaxies 4' east of the edge-on, though Muller would have probably resolved this trio. There are a number of galaxies in the area, roughly matching Muller's declination, so if he was too far west in RA then there are several additional candidates!

Édouard Stephan discovered NGC 7048 = St. 9-28 on 3 Aug 1866, apparently his first discovery. His uncorrected position was 5' too far E but he published an accurate position in list 9 that was reduced on 19 Oct 1878. At +46° declination, NGC 7048 is the most northerly object discovered by Stephan at Marseilles as he only searched up to the zenith. Thomas Webb independently found it on 14 Nov 1879 and announced his discovery in AN 96, 191. He noted the "star" BD +48°4004 was not stellar, but a "bluish ill-defined disc of about 4", surrounded possibly with a feeble glow." Ralph Copeland was notified and examined it with a spectroscope at the Dun Echt observatory and verified emission lines consistent with a gaseous nebula.
In 1919, Heber Curtis reported it was undoubtedly a planetary nebula based on a Crossley photograph and described it as "A rather faint oval, with slight traces of ring structure. It is about 60" x 50" in p.a. 20°±. The brightest portions are at the east end of the minor axis. There is a very faint central star." In 1920, Francis Pease reported it was "a planetary resembling the Dumb-bell nebula, about 1' diameter, weak axis in p.a. 170°. The central star is very faint."

Corwin noticed, though, an "anonymous" object in Esmiol's table is given with Stephan's original offset but using a different star. This leads to a position near NGC 7080 (was Stephan aware of Marth's discovery?). But Corwin found that Esmiol, like Stephan, misidentified the offset star.

There is no bright star near his position, but 40 tsec of RA following and 1.5' north is a bright, scattered group including 8th magnitude SAO 33352 at 21 21 39.8 +50 50 17. Copeland, observing at Birr Castle in 1871, noted it was a "Cl, vP, in milky way." and Reinmuth called it simply "a few B st", based on a Heidelberg plate. RNGC classifies this Milky Way asterism as nonexistent (Type 7) and Kharchenko et al, 2012, classifies it as a moving group so at least some of the stars may be related.

So, d'Arrest discovered NGC 7065 (also observed by Stephan) and Marth apparently discovered NGC 7065A, a larger, lower surface brightness companion 4' southeast. Interestingly, all three observers only found a single galaxy, though both MCG galaxies were observed in my 17.5" and fairly similar in ease of visibility. So, NGC 7065A should have received a separate NGC number -- unless Marth's position was very poor, and coincidentally matches NGC 7065A. The RNGC positions for both galaxies are 2' too far south (see my RNGC Corrections #4). See Harold Corwin's identification notes for more.

18" (10/8/05): this "nonexistent cluster" is located in a glorious low power Milky Way field. Several groupings (both large and small) caught my eye at 73x (67' field), but I was mostly drawn to a fairly distinctive 4' string of stars oriented NW-SE. At 225x, ~15 stars were packed into the string, most stars being mag 13-14 with a few fainter stars, and possibly over unresolved Milky Way background glow. This group would have likely caught John Herschel's eye as he swept the region, though it may be an asterism (not in Lynga).
John Herschel discovered NGC 7071 = h2119 on 19 Sep 1829 and recorded "A very poor and small cluster of an oblong figure. It is followed by a loosely scattered mass of stars." His position corresponds with a 7' to 8' curving string of stars. Surprising, Karl Reinmuth was unable to identify this group on a Heidelberg plate and noted "not found; = N7067?" Dorothy Carlson repeated this comment in her 1940 NGC Correction paper as well as in the RNGC.

Joseph Baxendell discovered NGC 7088 on 28 Sept 1880 using a 6" refractor at his private observatory in Birkdale, England. The discovery was announced in "A New Nebula", MNRAS 41, 48 (1880). The following history is from Wolfgang Steinicke.
Baxendell contributed only one object to the NGC. He published the discovery of a large faint nebula near M2 in Aquarius and described it being of "irregular oval form, its longer axis lying in a nearly east and west direction". It is 30' north of M2 and has a size of 75' x 52'. He writes "It seems to be similar in character to the large nebula near the Pleiades [found by Tempel], but is slightly less bright. I have, however, seen it on several nights, and have no doubt of its existence." But, its existence is the very problem!
NGC 7088 was seen visually by several observers, such as
Dreyer in 1885 with a 10" refractor (mentioned in the notes section of the
NGC), Bigourdan (1897, 12" refractor), Hagen (1915 and 1917, 16"
refractor), Wolf (1927, 6" refractor), O'Connor (1929, 15"
refractor), Becker (1930, 12" refractor) and Lehner (1930, 4"
refractor). The crucial thing is that, apart from these sightings, the object
could never be photographed (and was nicknamed "Baxendell's
Unphotographable Nebula"). Many attempts were made (Wolf, Baade, Shapley,
Strohmeier, Gürtler, Helwan), using different emulsions and filters, but the
result was always negative. The modern conclusion is: The object is not real
and all visual observations are due to physiological delusions, maybe caused by
reflections of the nearby bright cluster

Jean-Dominique Maraldi discovered M2 = NGC 7089 = h2125 on 11 Sept 1746 at the Paris Observatory. At the time he was tracking Comet de Chéseaux of 1746 with Jacques Cassini, son of Giovanni Cassini. Charles Messier made an independent discovery on 11 Sep 1760.
William Herschel first resolved the globular on 31 Jul 1783 with his 12-inch (small 20-foot) and commented "I can count 18 or 20 of the stars but they are so thickly set one behind another that their light mixed together makes a very strong glare." Observing M2 with the 18.7" on 21 Jul 1784 (sweep 242), he made an interesting description: "A cluster of stars extremely compressed in the middle and diminishing suddenly not in a manner of a round solid but rather like the frustum of a cone whose base (longer parallel side) is turned towards the eye." Again on 12 Aug 1785 (sweep 425), he recorded "an extremely rich, very compressed and very brilliant cluster of extremely small stars, 7 or 8' in diameter. The stars are plainly to be seen, especially on the borders where they are not so condensed." Observations were made on 5 different sweeps.
Herschel observed it at 240x with his 40 feet telescope (48" f/10) on 4 Sep 1799: "It appeared very brilliant and luminous. The scattered stars were brought to a good, well determined focus, for which it appears that the central condensed light is owing to a multitude of stars that appeared at various distances behind and near each other. I could actually see and distinguish the stars even in the central mass. The Rev. Mr. Vince, Plumian Profession or Astronomy at Cambridge, saw it in the same telescope as described."
On 12 Sep 1830 (sweep 288), John Herschel reported "A most superb cluster; round; stars eS; 12, 13, 14m; they are evidently globularly arranged, and not internally condensed towards the centre more than the spherical form would make them appear to be; but in the middle they blend into a blaze of light. It is like a heap of fine sand! With 9 inches aperture I can just see the stars; with 6 it is resolvable." William Parsons, the third Earl of Rosse, sketched M2 with his 36-inch by 1844 and published it in his "Observations on some of the Nebulae" (date of sketch not dated).

Charles Messier discovered
William Herschel first observed the globular on 31 Jul 1783 using his 12-inch (small 20-foot). He recorded "Power 200; it consists of very small stars; with two rows of stars, 4 or 5 in a line." He later wrote, "It is a difficult step i.e. if we divide the transition from the Pleiades down to the Nebula in Orion into six steps, this perhaps the 4th towards the real nebulas. The stars in this seem to be of two different sizes for I perceive 3 or 4 very visible ones branching out towards the north and several more exceedingly small at the sides. Towards the south in one place the light is very intense, but has all the appearance of crowded stars; so that there remains no doubt of the whole being stars." He viewed M30 as his first target with the 18.7" on 26 Oct 1783 at 120x: "I can distinctly count 10 stars; the nebulosity also where it is most compact is mottled and undoubtedly consists of stars." A sketch was made the next night and he commented "the rows of stars [star lanes on the north side] probably do not belong to the cluster."
In PT 1814, Herschel summarized his observations of M30 as a "brilliant cluster, the stars of which are gradually more compressed in the middle. It is insulated, that is, none of the stars in the neighborhood are likely to be connected with it. Its diameter is from 2' 40" to 3' 30". Its figure is irregularly round. The stars about the centre are so much compressed as to appear to run together. Towards the north, are two rows of bright stars 4 or 5 in a line." He speculated in his 1814 publication that the "lines of bright stars, although by a drawing made at the time of observation, one of them seems to pass through the center, are probably not connected with it."
John Herschel made the following detailed observation on 23 Sep 1830: "Fine cluster; irreg R, with two projections A, B, at its northern side. (See fig. 90.) A is directed from the central brightness and consists of 3 or 4 bright stars 12 m; its position taken with microm = 350.4°; B originates in the preceding side of the centre, and is directed in a position 331.7° in a line not passing the centre; diam = 6', stars = 12m; fine object; has a * 9 m preceding it (2 or 3 diameters by diagram)." From the Cape of Good Hope, he logged "Globular, B; lE; bM; 4' l, 3' br; all resolved into st 16m, besides a few 12m. Two lines of rather larger stars run out n[orth f[ollowing]."

Ralph Copeland discovered NGC 7114 on 2 Sep 1877 with a 15-inch Grubb refractor at Dunn Echt, Scotland while viewing Nova Cygni 1876 (discovered by Julius Schmidt on 24 Nov 1876). Copeland reported "through a low power eye-piece and a powerful direct vision prism, held between the eye and the eye-piece, the light of the star was found to be absolutely monochromatic." In Oct 1885, Lohse claimed the star was surrounded by a small nebulous disc (first reported in 1882). In the NGC notes and correction section, Lohse is mentioned but not Copeland. Sherburne Burnham observed the nebula in 1891 with the 36-inch refractor at Lick and noted "at times the new star did not seem to have a perfectly stellar appearance under moderately high powers, but rather to resemble an exceedingly minute nebula."

Guillaume Bigourdan discovered NGC 7133 = Big. 91 on 18 Sep 1884 while observing the NGC 7129 complex. According to Corwin, Bigourdan's offset is 1 min 26.8 seconds east and 3' 49.7" north of BD +65 1638. He described a "pretty extended area, perhaps 2' across, in which I suspect some extremely faint nebulosity, at the extreme limit of visibility." There isn't any visible nebulosity on the DSS at this offset and Harold Corwin classifies this number as non-existent. See his identification notes.
The RNGC classification is a diffuse nebula but there is no description. The RNGC position is 4' southwest of the center of NGC 7129, and it's not clear what object or section of the nebulosity the authors are referring to. The RNGC error is mentioned in my RNGC Corrections #4 and by Gordon Bond in Deep Sky magazine.

The brightest star is 25" due south of the mag 12 star and the faintest mag 15 star is at the west end of the arc. Nicely resolved at 280x and 410x. NGC 7131 lies 23' SW.
Christian Peters discovered NGC 7134 around 1860 with the 13.5-inch refractor at the Hamilton College Observatory in New York. He described it as "very small, but not very faint; nearly S of a star 11m." Herbert Howe, in his visual survey at Denver, reported "not a nebula; it simply a group of three or four stars of mag 13-14, which is about 40" south of a 10th mag star. A most careful scrutiny revealed no trace of nebulosity." The DSS confirms there are four mag 14/15 stars in an arc, just 30" south of a mag 12 star. Harold Corwin agrees with this identification. RNGC classifies this asterism as nonexistent.

At 285x it appears to be a double star, though the separation is quite small and the stars were not cleanly resolved in only fair seeing.
Frank Muller discovered NGC 7158 = LM 2-464 in 1886 with the 26" refractor at the Leander McCormick Observatory. Muller described a "neb*[estimated at mag 14]; *9.5 P 40° Δ2.8'." In 1898-99 Howe reported "this nebulous star is of mag 13. It may be double at 270° (west)." Howe's object is a close double star (fainter component to the west) about 30 seconds of RA east of Muller's rough position (nearest min of RA). Bigourdan also measured this same multiple star on 10 Sep 1888.
Harold Corwin also identifies NGC 7158 as this object
(calling it a triple star). A mag
10 star is 2.9' in PA 40°, clinching this identification. The RNGC misidentifies

Heinrich d'Arrest discovered NGC 7161 on 13 Sep 1862 with the 11-inch refractor at Copenhagen. He made two observations on consecutive nights and mentioned a mag 11-12 stars precedes by 11 seconds of time. On the 14th, he described this object as a small group of stars (19th mag), between two (16th mag) stars. About 2' south of his position is a pair of mag 15 stars and 1' further south is a fainter and closer pair with a third extremely close pair to its south. Karl Reinmuth reported this as a "double star 15 dist 0.2', 0 deg; bet 2 st ssp/nnf." [the northernmost pair].

William Herschel discovered NGC 7184 = H. II-1 = h2143 on 28 Oct 1783, in a trial (horizontal) sweep. He recorded it as internal discovery #1 and made a sketch that is shown in Wolfgang Steinicke's book on Herschel. Another observation was made on sweep 609 (13 Oct 1786, starting again using the front-view): "faint, much extended, easily resolvable, making an angle with two pairs of stars, which are situated in a line from np to sf. The nebula is also followed by a small star, which continues the angle the nebula makes with the two pairs of stars."
John Herschel made the single observation on 23 Sep 1830, "pB; pL; vmE; position = 64.3°; pretty suddenly very little brighter middle; 2' long." Bir Castle assistant George Stone observed NGC 7184 on 7 Sep 1850 and reported seeing 4 knots or faint stars in the nebula.
Photographs taken with the 30-inch reflector at the Helwan observatory in Egypt in 1919-20 revealed "spiral with rather compact but well defined whorls [spiral arms] and a B sharp stellar nucleus surrounded by a rather brighter patch of nebulosity. Ther are signs of absorption in the northwest portion."

The group is a distinctive asterism of about a dozen mag 11-12 stars that is elongated NW to SE and extends 6'x1' or nearly twice this length if you include some scattered stars extending NW. The group stands out well at low power and is a good impostor of a scattered cluster.

Based on Heidelberg plate, Karl Reinmuth reported this object as a "Cl, E, pP, st sc, st 9...15; IC 5160 [galaxy] n." RNGC misclassifies the number as nonexistent, although the group of stars may be an asterism.

the fairly prominent, long dark lane that begins near M39 and heads east in the

William Herschel discovered NGC 7209 = H. VII-53 = h2147 on 19 Oct 1788 (sweep 868) and recorded "a large cluster of pretty compressed considerable large stars, above 15' diameter." John Herschel made two observations, first recording on sweep 209, "place of a * 10m near the middle of a fine L p rich cluster; 50 stars from 10m to 13m counted. It fills field. Moon full."

John Herschel discovered NGC 7210 = h2148 on 17 Nov 1827 and recorded "eF; R; bM; ill-defined; a vF double star 45° north-preceding 4' dist points just to it." Both his RA and Dec are marked as very uncertain (::) and there is nothing fitting his description near the position. There were three unsuccessful attempts to find this object at Birr Castle (twice with passing clouds) and Karl Reinmuth reported it was not found on a Heidelberg plate. But JH made two transcription errors contributing to the erroneous NGC position. His position in the General Catalogue (GC) and repeated in the NGC is 1 degree too far south. Furthermore Harold Corwin found (April 2016), that he made a transcription error in copying the RA from his logbook to the Slough Catalogue, so the RA (marked as uncertain) is 1 hour too small. Correcting both of these errors, the position of NGC 7210 = h2148 (as well as the description) matches NGC 7487, later discovered by Lewis Swift. None of the modern online sources (NED, HyperLEDA, SIMBAD) connect NGC 7210 with NGC 7487.

William Herschel discovered NGC 7234 = H. VIII-63 on 16 Oct 1787 (sweep 768). He recorded "A small cl of stars, the stars pretty large but not many of them." Caroline's reduction was off the west side of the cluster, though Auwers' 1862 reduction falls closer to the center. John Herschel observed the cluster twice (first on 16 Dec 1830) and correctly equated his father's VIII-63 with h2154 in the Slough Catalogue in 1833. But he made an error in compiling the GC in 1863 and created two entries for the cluster with H. VIII-63 = GC 4771 placed ~18' too far south. Dreyer repeated this error in the position of NGC 7234.
Because of the poor NGC position, Reinmuth looked in the wrong place and concluded "no distinct cluster" (repeated by Dorothy Carlson and the RNGC). But NGC 7234 = NGC 7235, with discovery credit to William Herschel.

John Herschel observed NGC 7235 = h2154 on 16 Dec 1830 and recorded "a * 10m, the chief of a p compact cluster of 15 or 20 stars 10...17m. One, 11m, is of a ruby colour." His mean position (measured on two sweeps) is accurate. He correctly equated the cluster with his father's H. VIII-63 (= NGC 7234) in the Slough Catalogue, but later assigned two numbers in the GC with an inccorect position for his father's discovery. Dreyer followed the GC in compiling the NGC, so the position of NGC 7234 is ~18' too far south. So, NGC 7235 = NGC 7234, with discovery credit to William.

Rather an equivocal object, whether nebulous or a group, but I incline to regard it as a nebula." On a later sweep (14 Sep 1835), he wrote "pB; irr R; 25"; involves a double star (13m + 14m)." So, he clearly resolved the two nuclei.

The description of 7285, discovered by Lassell [Marth], is "Nebs. * 1' dist from 7284." I judge 7285 to be simply one of the components of 7284. Both seem to be nebulous stars. The brighter one is of mag 12.5 The other is of mag 13, and lies at P.A. 60°, distant about 40". Neither of the stars appeared to be double. I could not see any nebulosity uniting them, but the sky was rather dull."

Truman Safford discovered NGC 7291 = Sf. 56 = St. 8a-18 on 1 Oct 1866 and recorded "pF, pS, neb middle to a nucleus." His position is accurate. Édouard Stephan observed the galaxy on 15 Sep 1876 (perhaps aware of Safford's discovery) and listed it as new in his discovery list 8a (#18). Stephan was credited in the GC Supplement and NGC due to the late publication of Safford's list. This was the case with ~20 out of 64 discoveries by Safford.

48" (10/29/16): at 813x; bright, fairly large, very irregular appearance. A faint star is superimposed just south of a very small brighter nucleus or knot. A bright "bar" extends through the nucleus WNW-ESE, (length ~50"), ending at a fairly bright knot at its WNW end. The knot (HII complex/OB assocation?) appears ~10"x7" SW-NE. A low surface brightness halo on the north and south side of the bar is roughly oval 3:2 and increases the overall size to ~1.5'x1.0'. Situated in a fairly busy star field.

18" (11/13/07): superb view at 115x and OIII filter, slightly elongated WNW-ESE, ~14'x12' including a faint extension or filament on the west side. The bright rim is relatively thick and brightest along the north to NE side within the interior of the annulus (not at the very edge). A star is embedded at the west edge of this large, enhanced arc (due east of the mag 10.5 star just off the NW edge). The opposite SW rim is also enhanced in brightness and thicker. The rim is weakest and thinnest at the WNW end, but with averted vision this end bulges out due to a faint extension or large filament (second ring) that begins just south of the western side of the rim and extends north towards the mag 10.5 at the NW edge of the halo.
17.5" (10/2/99): gorgeous view at 100x and OIII filter. This huge, annular PN is 15'x12' in size and slightly elongated E-W due to an extension on the west side. The thick annulus is mottled and irregular with brighter regions along the N, NE and SW edge. The west side is slightly weaker but very faint extensions from the north and south side towards the west cause the rim to bulge on this side (part of a second ring). The west edge of the halo more gradually blends into the background near a mag 11 star off the west side. At 220x without a filter about a dozen stars are superimposed. The mag 13.5 central star is easy along with a similar star a couple of arc minutes following.
13.1" (8/16/82): the "Helix" nebula is extremely large, about 15' diameter, clearly annular. Significant contrast gain with OIII filter permits observation even from the Bay Area. The fairly bright rim is non-uniform appearing brighter along the north side. About 7 stars are superimposed including the mag 13.5 central star. Appears best at low power due to size and relative low surface brightness. Easy in the 80mm finder.
8" (10/4/80): huge annular planetary is fairly bright at low power using a Daystar 300 filter. The rim has an irregular surface brightness.
15x50 IS binoculars (8/27/11): easily visible in binoculars using a pair of narrowband filters.
Karl Ludwig Harding discovered NGC 7293 = Au 48 in 1823 at Gottingen University Observatory, probably using an 8.5-inch reflector built by William Herschel. According to Wolfgang Steinicke, Harding published a list of 8 new nebulae in Astronomisches Jahrbuch, although the Helix Nebula is the only object he actually discovered, the others being observations of previously discovered nebulae. Harding's list wasn't checked until 1857 by Winnecke and not generally known by others. Ernesto Capocci independently discovered this huge planetary in late 1824 at Capodimonte Observatory in Naples, but his position was over a degree too far west. In 1856, Christian Peters reported another discovery while he was at Capodimonte Observatory around 1850 (AJ 2, p16). As late as 1884 Jermaine Porter also reported a discovery, although at that point it was already in John Herschel's General Catalogue. NGC 7293 was apparently just the second deep sky object discovered after William Herschel last sweep #1112 on 30 Sep 1802 (a gap of 20+ years).
Based on a September 1912 photograph (4 hour explosure) taken with the Crossley reflector at Lick, Heber Curtis wrote "I would suggest that this interesting object be referred to as "The Helical Nebula in Aquarius" [to distinguish it from the the Helical Nebula in Draco, NGC 6543]. In 1917, Robert Innes, at the Union Observatory in Johannesburg, noted it was "seen in both the 3-inch and 9-inch telescopes. Large, but no detail." and probably based on Curtis' comment, he referred to it as the "Helical nebula in Aquarius." The Heix was photographed several times with the 30" reflector at the Helwan Observatory near Cairo and the 1921 bulletin reported "A recent plate shows an additional much fainter loop in the north-following portion, which extends 15' from the centre of the nebula."

Dreyer also searched unsuccessfully for NGC 7304 on 29 Sep 1875 at Birr Castle. A double star is 2' southwest of NGC 7303 (opposite direction).

Édouard Stephan discovered NGC 7318 = St 8a-20, along with the other members, 27 Sep 1873. He reduced the position on 23 Sep 1876 and included it in his discovery list 8a (#20). He didn't resolve the NGC 7318 pair, so the two components are often called NGC 7318A and 7318B. Harold Corwin carefully re-reduced his offsets and found that Stephan measured the brighter western component, although his position is just off the nucleus of the eastern component.
Shapley and Ames mentioned NGC 7318 is "bi-nuclear and probably represents two interpenetrating system" in 1930BHarO.878....6S.

Lawrence Parsons, the 4th Earl of Rosse, discovered NGC 7326 on 7 Oct 1874. His micrometric offset (also measured in 1875) from NGC 7331 (153" in PA 278°) points to a close double star 2.5' preceding the nucleus of NGC 7331. It's also shown unlabeled on the constructed sketch in the 1880 publication. Dorothy Carlson also equated this number with the double star based on Mount Wilson and Lick Observatory plates.

17.5" (10/17/98): this number refers to one of the several nonexistent NGC entries in the NGC 7331 vicinity. A possible candidate suggested by Harold Corwin is a mag 13 star near the tip of the northern extension of NGC 7331. This single star appeared stellar, although it seems plausible that it might look slightly nebulous due to the faint background haze of the galaxy. Other fainter nearby stars may instead apply to NGC 7327.
Wilhelm Tempel discovered NGC 7327, along with
Harold Corwin suggests the mag 13 star at 22 36 57.3 +34 28 02 (2000) as a reasonable candidate. Another possibility is the compact galaxy PGC 69261, which has a bright star superimposed (the RNGC misidentifies this galaxy as NGC 7325). Unfortunately, Tempel didn't leave any additional clues as to the identification of NGC 7327, so any assignment is really a guess. The identifications in the NGC 7331 group are discussed in my Deep Sky magazine article for Fall 1986.

On 13 Sep 1784 (sweep 269), he recorded "very bright, considerably large, much elongated, much brighter in the middle, resolvable." At the same time, the brightest companion NGC 7335 was discovered, although Wolfgang Steinicke states that Stephan's quintet was just below the southern limit of the sweep and was missed (both Herschels).

18" (8/1/08): faint or fairly faint, small, elongated 3:2 N-S, 0.4'x0.25'. A mag 14.5 star on the east side confuses the view. Located 5' SE of NGC 7331.
18" (7/20/04): at 322x appears faint, very small, round, ~20" diameter. The observation is confused by a mag 14 star that is attached on the southeast side and the galaxy appears to bulge out from the star towards the NW.
17.5" (8/27/87): fairly faint, small, slightly elongated. A mag 14-14.5 star attached at the SE end just 9" from the center confuses the observation as the galaxy appears like a close double. Located 5.2' SE of the center of NGC 7331 in a group of four faint companions.
17.5" (9/14/85): faint, very small, round, star attached at SE end.
13.1" (9/29/84): very faint, very small, round. A mag 14 star is superimposed at the SE side. This is the third faintest of the four companions to NGC 7331 and is located 5' SE of the center of NGC 7331. NGC 7340 is 4' NE.
George Johnstone Stoney discovered NGC 7337, along with NGC 7336 and 7340, on 10 Sep 1849 and noted "4 knots following [NGC 7331]." A diagram was made 2 nights later and NGC 7337 was labeled "E". Despite an accurate position, NGC 7337 was reported in the 1908 Catalogue of new nebulae and clusters found on plates taken with the Crossley reflector, generally of bright nearby galaxies [NGC 7331 in this case]. The plates were taken by Keeler in 1898-00 and this galaxy was recorded as #716 out of 744.

Wilhelm Tempel discovered NGC 7338, along with NGC 7327, in 1882 with the 11" refractor near Florence and reported in the narrative portion of his fifth paper (AN 2439). No position was given but NGC 7338 was noted as located "between the four brighter companions following [NGC 7331], closer to the southern two [NGC 7337 and 7340]." There are no additional galaxies he might have seen, so this number probably refers to a single or double star. Harold Corwin suggest NGC 7338 is probably the faint double star about 3' southeast of NGC 7335, which forms an isosceles triangle with NGC 7337 and 7340. The identifications in the NGC 7331 group are discussed in my Deep Sky magazine article for Fall 1986.

William Herschel discovered NGC 7339 = H. II-234 = h2175, along with NGC 7332, on 19 Sep 1784 (sweep 278). His description reads, "faint, extended, resolvable, the direction of the extent different from that of the foregoing [NGC 7332]." On 20 Oct 1784 (sweep 302) he reported "extended of the size of the foregoing [NGC 7332], and the extension in a different direction, almost at rectangles to the former; the direction nearly in the parallel, about 1 1/2' in length."
On 13 Sep 1830 (sweep 290), John Herschel recorded "vF; mE in parallel; 60" l; the following of two [with NGC 7332] and a third suspected." There is no other nearby third object, so perhaps he glimpsed a very faint star.

All within a rich Milky Way field. A wide strip of nebulosity is attached near the southeast vertex and extends to the southwest. A dark band appears to separate this strip from the triangular patch. The surrounding region appears weakly nebulous and the "edge" can be traced with some certainty further the north. The brightest star is mag 8.5 DH Cep at the west vertex of the cluster. This star is a very rare spectroscopic eclipsing pair of massive O5.5/O6.5-type stars and the main ionizing source.
17.5" (7/31/92): at 100x, about 40 stars in a 10' diameter. The brighter stars form a "V" or chevron pattern. The brightest star is at the west tip of the "V" and is an unequal double mag 8.6/13. The cluster appears to be encased in nebulosity especially from the mag 8.6 star to the star at the east tip of the "V". Using an OIII filter the nebulosity was quite prominent with some structure and encased the entire cluster. A lane of nebulosity oriented SW-NE extends beyond the cluster from the star at the east end of the "V" and nebulosity also extends west of the mag 8.6 star.

Bindon Blood Stoney discovered NGC 7389, along with NGC 7383 and 7384, on 27 Nov 1850. It was unlabeled on the diagram of the group and not very accurately placed. John Herschel apparently thought it was Delta (NGC 7387), resulting in a poor position in the GC and NGC. Dreyer measured an offset and position angle from NGC 7390 on 11 Oct 1873.

Other sources identify the eastern edge-on component as NGC 7415, but the number should probably apply to the entire double system as Marth didn't resolve the pair and they are pretty comparable in brightness.

Edward Cooper discovered NGC 7447 = Au 49 on 8 Oct 1855 with the 13.3-inch refractor at the Markree Observatory in Ireland. While compiling the comprehensive Markree Ecliptic Catalogue he thought he found a nebulous mag 11-12 star. Arthur Auwers searched and reported "no nebula can be seen" using the Heliometer at Konigsberg. Wilhelm Tempel was also unsuccessful on several attempts (AN 2284), as well as Sherburne Burnham (Publ of Lick Observatory, II).

A mag 14.5 star lies 2.1' SSW. This galaxy is not listed in any modern catalogue and the identifications of NGC 7452 and NGC 7459 are uncertain due to poor positions by Lewis Swift.
Lewis Swift discovered NGC 7452 = Sw. 2-95, along with NGC 7455 and NGC 7459, on 14 Oct 1884 and recorded "eeeF; pL; R; e diff.; np of 2 [with NGC 7459]." His position falls within a small cluster, 9 seconds of RA east of UGC 12302. RNGC, MCG and PGC identify UGC 12302 as NGC 7452. It's the brightest member of the cluster and a double system with nuclei only 10" apart. Herbert Howe apparently also identified this galaxy as NGC 7452 (MN, Vol 60, 129).
As an alternative, Corwin suggests that NGC 7452 = LEDA 1306660, the second brightest in the cluster. This places NGC 7452 21 seconds of RA preceding Swift's position (matching in dec). This identification was first made by Kobold in his 1907 catalogue. NED and HyperLeda now both use this identification. This implies NGC 7459 = UGC 12302, which is 12 seconds of RA larger (Swift's difference is 20 seconds).

48" (11/2/13, 10/30/16 and 10/28/19): The view of NGC 7479 was mesmerizing at 488x and 610x. Compared to the view last October, I noticed the fainter eastern arm was broader (split in two parallel branches on images) and although diffuse, obviously extended all the way to the southern edge of the galaxy, nearly reaching a mag 16 star. Also the bright arm on the western side of the bar dimmed as it extended north, but wrapped all the way or just beyond a mag 15.7 star situated 48" SW of the bright mag 12.5 star off the north end of the bar. The western arm clearly had a clumpy appearance with a couple of brighter patches. Near the south end of this arm [1.1' SSW of center] is a very faint quasi-stellar knot, which is catalogued as HII region #45 in Hodge and Kennicutt's 1983 "An Atlas of H II regions in 125 galaxies". Another brighter knot, ~12"x6", is at the southwest end of the arm [1.5' SW of center]. This is region #57 in the HK Atlas. A faint edge-on (V = 17.8), lies 3.5' NW of NGC 7479.
48" (10/22/11): NGC 7479 is probably the best barred spiral in the northern sky. At 488x and 610x the central bar appears very bright and extended over 2' N-S. The bar had a mottled appearance, bulging slightly in the center, was broadly concentrated with a small bright core. A bright mag 12.5 star is at the north end of the bar, 1.3' from the center.
At the northern end, an arm emerges from the bar and begins to curve counterclockwise to the east, but abruptly dims and merges with the halo on the east side. At the south end of the bar, a beautiful sweeping arm wraps counterclockwise around the south of a superimposed mag 13.5 star, extending to the west side of the core. This prominent arm dims and ends just north of an extremely faint HII knot (stellar) in the arm, which is catalogued as object #4 in Rozas' et al 1999 A&AS paper "Global properties of the population of HII regions in NGC 7479 from photometric H-alpha imaging". A mag 16.4 star is 0.7' due west (outside the arm) of this knot. A mag 15.7 star is also superimposed between the faint HII knot and the bright star at the north end.
18" (11/7/07): I was surprised the thin spiral arm was readily visible from Lake Sonoma extending from the south end of the bar and wrapping outside the mag 13.5 star situated 50' SW of the core. This arm dimmed out roughly due west of the star. The central bar extends 2.4'x0.6' N-S and contains a bulging 25" core that broadly brightens to an occasional faint stellar nucleus with direct vision. Barely off the north end of the central bar is a mag 12.5 star (1.3' due north of center) and there was just a hint of the spiral arm at the north end of the bar beginning to bend towards the east.
18" (10/19/06): fairly bright, fairly large, the main bar appears elongated 3:1 N-S, moderately concentrated with a bright core. A mag 12.5 star is just off the north tip of the bar. At the south end an extension is generally visible with averted vision hooking back sharply on the west side towards the north. This spiral arm dims as it hooks but intermittently appears to sweep due north though does not extend as far as the mag 13.5 star off the SW side of the core.
17.5" (7/19/90): this is one of few northern barred spirals in which the structure is clearly visible. A bright bar is oriented N-S with a bright core and nearly stellar nucleus. A mag 13 star is off the north edge 1.4' from center and a fainter mag 14 star is 47" SW of center. A thin curving spiral arm attached at the south end curves to the west and then north beyond the mag 14 star SW of the core. This arm parallels the bar along the west side about 90°. At the Sierra Buttes, the spiral arm was held almost continuously with averted vision. Located 3.3' NNE of a mag 10 star.
17.5" (10/12/85): thin curving arm clearly seen attached at the SW end curving to the north around a faint star.
13.1" (9/29/84): fairly bright, elongated ~N-S. Strong impression of a dark lane or gap on the west wide and brief hints of haze beyond this gap, particularly around the south end towards the west (spiral arm).
13.1" (11/5/83): fairly bright, elongated N-S, bright core. Two faint stars are west and north.
William Herschel discovered NGC 7479 = H. I-55 = h2205 on 19 Oct 1784 (sweep 299). He described it as "faint, much extended, resolvable [mottled], near 3' in length and about 1' in breadth; I see 2 or 3 stars in it; but they do not seem to belong to it." On 23 Nov 1785 (sweep 476) he noted "cB, mE nearly in the direction of the meridian; about 4' long, about 2' broad, gradually brighter in the middle." A sketch, showing the long bar (but no arms), was included in his 1811 publication (fig. #16) as an example of "Nebulae which are gradually brighter in the middle."
George Johnstone Stoney or Lord Rosse sketched NGC 7479 on 10 Sep 1849 (figure 4 in the 1850 PT paper). The sketch shows a single prominent spiral arm wrapping nearly completely back to the bar, though the form was uncertain: "Spiral, but query whether this is not more properly an annular than a spiral nebula." Wilhelm Tempel, John Herschel and Heinrich d'Arrest made additional sketches.
In the 1900 paper "The spiral nebula H. I 55 Pegasi" (1900ApJ....11....1K), Lick astronomer James Keeler compared the various sketches of NGC 7479 with a photograph taken with the Crossley reflector to demonstrate the subjectivity of sketches and their limitations compared to photographs.

Édouard Stephan discovered NGC 7490 = St. 10-39 on 2 Oct 1867 and recorded a rough position (12' too far SW) in his logbook. He measured a micrometric position on 11 Oct 1879. Edward Holden found this galaxy again on 21 Aug 1881 with the 15.6-inch Clark refractor at the Washburn Observatory. He assumed it was new and reported it as #23 in a list of new nebulae (Publications of the Washburn Observatory, Vol I). Both Stephan and Holden were credited with the discovery in the NGC.

The main portion of the nebulosity (Sh 2-158) is elongated SW-NE and extends 3'x2'. Using an OIII filter, fainter nebulosity extends on the NE side, making an oval 4.5'x3'. The brightest portion is on the southwest side and this high surface brightness area encases the faint star mentioned above.

On 26 Nov 1788 (sweep 887) he noted "2 pretty small stars involved in nebulosity, about 2' l and 1 1/2' broad, pBM." In his 1814 PT paper Herschel argued that this was too unusual to be line of sight arrangement and the stars had formed within the nebula! His eyepiece sketch was included (fig. 3) as representative of the class "two stars with nebulosity between them."

Heinrich d'Arrest discovered NGC 7574 on 2 Oct 1866 with the 11-inch refractor at Copenhagen. There is nothing near his single position. Karl Reinmuth reported it was not found on Heidelberg plates, and this was repeated by Dorothy Carlson and the RNGC. Harold Corwin suggests that if d'Arrest made both a 30' error in declination (too far south) and 30 seconds in RA (too far east), then NGC 7574 is equivalent to NGC 7568, discovered by Stephan 10 years later. As both errors involve single digits, this solution is reasonable (though not certain).

Horace Tuttle discovered NGC 7581 on 11 Jan 1875 with the 26-inch refractor at the U.S. Naval Observatory. Although Holden is credited with the discovery in the NGC, Wolfgang Steinicke found in the USNO observations for 1875 the entry "Jan. 11. Nebula (nova). In looking for Encke's Comet, found a vF, elongated nebula [alpha] = 23h 11m.4 [delta] = +3d 59. T[uttle].". There is nothing near his position. In Die Herschel Nebel (1927), Karl Reinmuth states "not found, =N7541". NGC 7541 is 3 minutes of RA west and 8' south of Tuttle's position, but there is a mag 12-13 star just east, which matches the NGC description. So despite the very poor position this identification is possible. See Harold Corwin's notes for more.

A mag 14 star is superimposed along the northern flank towards the NE end. The SW end tapered somewhat but the NE end was oddly truncated due to dust. A mag 12.8 star is 1.5' E of center. Last in the superb Grus Triplet with NGC 7582 and 7590.

It was broadly concentrated but there was no distinct core or nucleus. The surface brightness was uneven or mottled, though, likely due to spiral structure or dust. The southwest end appeared more tapered and had a very faint extension at the tip, while the northeast side ends more abruptly. A mag 14 star is superimposed on the north side, 0.8' NNE of center. A mag 12.8 star is off the east side, 1.5' from center. NGC 7590 lies 5' WNW.

James Dunlop discovered NGC 7599 = D 477.2 = h3981, along with NGC 7582, on 14 Jul 1826 and recorded "two very small round nebulae, nearly the same RA, and differing about 1' in polar distances." His single position was 30' too far W. John Herschel observed the pair of 2 Sep 1836 (sweep 728) and logged "F; pmE; gradually brighter in the middle; 3'; [the following of two]."
Harold Corwin notes that Lewis Swift's XI-227 = IC 5308, found on 8 Aug 1897 and described as "eeF; S; cE; f of 3; f of 7599.", is probably a duplicate observation. Swift likely confused NGC 7590 as 7599 and assumed Sw. 11-227 was new. See Corwin's historical notes.

There is a long-standing redshift controversy with this pair first mentioned by Arp in ApL, 7, 221, 1971. NGC 7603, the brighter galaxy, has a redshift z = .029 (~390 million ly) while its companion NGC 7603B has a much higher redshift z = .057, placing it about twice the distance (~740 million ly). But there appears to be a luminous bridge connecting the objects that is easily visible on the DSS. Also two quasars with much higher redshifts (z = .391 and z = .243) are embedded exactly on line of sight at the start and end of the bridge.

NGC 7619 is the most distant known galaxy mentioned by Hubble in his 1929 paper "A relation between distance and radial velocity among extra-galactic nebulae", although its recessional velocity of +3779 km/sec wasn't used in his graph of the velocity-distance relationship. Hubble mentioned a preliminary distance of 25 million l.y.

A low contrast dust lane wraps along the eastern edge of the core around to the south. The dust lane continues slicing through the galaxy towards the west, cutting off a southern piece of the galaxy, which mimicks the appearance of a broad spiral arm. A slightly brighter knot or patch is at the east end of this section, about 20" S of center. The outer halo was slightly fainter on the southeast side. Note: On the SDSS, there are two distinct, intersecting dust lanes, east and southwest of the core.

Lewis Swift discovered NGC 7627 = Sw. 6-95 on 18 Nov 1886 and recorded "vF; S; vE; coarse double star near north; the double star is between 2 stars." There is nothing near his position. Herbert Howe mentions in his 1899-00 observations that "I failed to find this on two nights. In reply to a letter of inquiry, Swift says that this is identical with 7641, one of Stephan's nebulae which I have measured. With this opinion I agree, having seen near 7641 the "2 star n" mentioned by Swift." Dreyer repeats this conclusion in the IC 2 appendix. If NGC 7627 is identical to NGC 7641, then Swift's position is off by 1.6 tmin in RA (too far west) and 10' too far north. His comment "vE" applies to this galaxy though the "coarse D * nr n; the D * is bet 2 stars" is not a good match. So this identification is uncertain. RNGC classifies the number as nonexistent.

The main section hooks around the involved star to the east.
William Herschel discovered NGC 7635 = H. IV-52 = h2235 on 3 Nov 1787 (sweep 773). He recorded "a bright star with faint nebulosity; but I saw it too late to verify it, as in the north I cannot follow the stars [side motion wasn't possible]. I rather suspect a deception." On 26 Nov 1788 (sweep 887) he added "a star about 9m with very faint nebulosity of very little extent." He included these description in his 1791 PT paper "On nebulous stars, properly so called."
Hubble announced NGC 7635 as a new planetary in his 1921 paper "Twelve New Planetary Nebulae", though he noted it "may possibly be transition forms between planetaries and diffuse gaseous nebulase." He again called it a giant planetary nebula in the 1922 paper "A general study of diffuse galactic nebulae." John Reynolds wrote an article in a 1924 issue of "The Observatory" titled "A remarkable planetary nebula in Cassiopeia", though didn't reference Hubble's earlier listings. Even in the early 1970's NGC 7635 was considered a possible or probable planetary (see ApJ, 167, 491-498 (1971)), though it was not included in Kohoutek's Catalogue of Galactic Planetary Nebulae (CGPN).

Lewis Swift discovered NGC 7644 = Sw. 5-100 on 29 Sep 1886 and recorded "vF, pS, lE." There is nothing reasonably bright near his position and the description is too generic to be of help. However, 74 seconds of RA due east is the double system NGC 7651, which Swift discovered earlier in the month on 1 Sep 1886 and placed correctly. Most likely NGC 7644 is a second observation of NGC 7651. Harold Corwin also suggests NGC 7643 as a possible candidate. See his notes for more.
The RNGC misidentifies 2MFGC 17581 = PGC 1445975 as NGC 7644. This is an edge-on galaxy situated 1.7' east-northeast of NGC 7651 and too faint to have been seen by Swift.

with
17.5" (8/25/95): very faint, very small, probably elongated 3:2 NW-SE, 30"x20". The view is severely hindered by mag 11.5 star that is attached at the northwest end! It was difficult to determine the dimensions and orientation due to glare from star and faintness of galaxy.
Frank Muller discovered NGC 7646 = LM 2-474 in 1886 with the 26" refractor at the Leander McCormick Observatory. He reported "mag 14.5; 0.2'x0.1', E 260°, neb?; *9 in PA 10° at 3.6' separation." There is nothing near his rough position, though 8' north is IC 5318 = PGC 71338. All modern catalogues identify this galaxy as NGC 7646, although NED comments the identification is uncertain.
Harold Corwin notes several inconsistencies with Muller's description; the elongation is NW-SE (not ~E-W) and the star at 3.6' separation is 10° west of north, not east. A more serious omission, though, is that Muller makes no mention of the bright, superimposed star on the west side. So, this identification is very unlikely.
In 2016, Yann Pothier suggested NGC 7646 is the double star at 23 24 32.3 -11 59 07. Harold Corwin agrees this is a good candidate as the position angle of the pair matches Muller's estimate and a star is at the required separation and position angle matching Muller's description.

V = 8.3; Size 32"x28"
48" (10/24/14): superb view of the double-shell structure at 610x and 813x. The inner shell is elongated ~3:2 SW-NE, ~18"x12", and contains a remarkable, bright thin rim, so it appears like a racetrack with a dark interior. This delicate but high surface brightness ring is brightest along a 90° arc around the northeast end and nearly as bright in a matching 90° arc on the southwest end. The rim is noticeably weaker on the west and east sides. The elongated darker hole spans a large percentage of the inner shell and was punctuated by a faint, but steadily visible central star.
The outer shell is twice the size (~35"x25"), slightly less elongated, and a bit offset in its major axis (SSW-NNE). The outer rim also has two brighter arcs or strips, but only 25°-30° in length. The more prominent arc is on the southeast side with a weaker strip symmetrically placed on the northwest edge. These strips are 90° offset from the much brighter inner arcs. The outer shell appears irregular in surface brightness with an impression of striations. Surrounding the outer shell there appeared to be a very low surface brightness outer halo.
18" (9/10/07): viewed this gorgeous double-shelled planetary at 807x in good seeing. The outer envelope is a sharply defined 35"x25" oval, oriented SSW-NNE. Roughly halfway to the center is a remarkable, thin oval ring oriented SW-NE (slightly offset in orientation compared to the outer shell) of very high surface brightness. This annular ring is brightest along a 90° arc on the south side and is also enhanced along a shorter arc along the northern part of the ring. The ring fades and appears broken with a gap along the west to WNW edge. Inside the ring is a darker oval hole that is weakly luminous.
18" (10/19/06): In steady seeing, the double-shell structure was remarkable at 807x (7mm Pentax + 2.5x Powermate). The outer envelope is noticeably oval SW-NE, ~35"x25". Embedded within this envelope is a fairly thin, very bright inner ring with a sharply defined outline. The ring was irregular in surface brightness but clearly brightest at the SW and NE ends of the ring (ends of the major axis). The ring fades on the NW side and there was a small, distinct gap in the ring at the NW end. The surface brightness of the inner ring was high enough to give a glowing "electric" quality with an impression of a rope-like or twisted structure. The center of the ring was much darker than the ring and formed a substantial dark oval at this magnification, but was still clearly luminous.
17.5" (9/19/98 and 10/13/01): at 500x, this blue high surface brightness planetary has a beautiful double-shell structure with a small, dark center. The bright inner structure has a delicate, embedded thinner ring of very high surface brightness, though weaker at the following end. In the center of this ring is a small, darker hole. The fainter, outer envelope is elongated SW-NE, ~35"x25", giving an asymmetric appearance with the outline of the inner ring.
17.5" (10/12/85): extremely bright, very high surface brightness, fairly small, easily takes very high power. At 410x, the planetary appears weakly annular with a slightly darker center. There is a second outer shell, which exhibits subtle structure due to an irregular surface structure, blue-green color is evident. Central star not seen.
13.1" (9/11/82): darker center at 288x, faint outer shell.
8" (8/15/82) : slightly darker center at 300-400x, irregular surface brightness.
William Herschel discovered NGC 7662 = H. IV-18 = h2241 on 6 Oct 1784 (during sweeps 281-285, which was made off the meridian in the east). He described it as "bright, round, a planetary [with a] pretty well defined disk, a little elliptical, perhaps 10" or 12" diameter." This may be the first time "planetary" is actually used although earlier, Darquier describes M57 "... as large as Jupiter and resembles a fading planet." In the 1785 PT paper ("Construction of the Heavens"), he wrote "When it is viewed with a 7 feet reflector [6.2"], it is not nearly so well defined as with the 20 feet diameter [18.7"]...taken with 278x, 15" diameter." On 3 Oct 1790 (sweep 964) he wrote, "a very beautiful object, with a very small star following; giving one the idea of a large planet with a very small satellite." Jean Dominque Cassini had mentioned the idea of a satellite after observing NGC 7662 during a visit (along with Méchain) on 27 Nov 1787. According to Wolfgang Steinicke, Herschel observed NGC 7662 a total of 10 times including with his X-foot (24" f/5) on 1 Jan 1807. A small sketch (fig. 36) was included in his 1811 paper as representative of planetary nebulae.
On 1 Oct 1828 (sweep 183), John Herschel recorded "A fine planetary nebula. Diameter 12"; with 240 beautifully defined, light, rather mottled, and the edge the least in the world unshaped. It is not nebulous, but looks as if had a double outline, or like a star a little out of focus. A perfect circle." He measured the 13th magnitude star ~50" NE of center several times (interested in it as a possible satellite of the planetary) and noted "These satellites of planetary nebulae out to be especially attended to."
32 observations were made at Birr Castle. Lord Rosse and assistant George Johnstone Stoney on 31 Oct 1848: "Has a central spot, at moments very dark." Rosse and Stoney made sketches on 16 Dec 1848 revealing the double ring structure and brighter arcs (1850 publication, Fig. 13). Rosse included NGC 7662 in the list of objects showing "dark spaces" in his 1850 publication. Stoney's sketch on 16 Sep 1852 (Plate XXX, Fig. 40 in the 1861 Monograph), using a freshly polished speculum, shows a prominent central star within a spiral shaped nebula and well-defined "arms".
Using a 9.5" refractor in 1855, Father Secchi described (and sketched) a slightly darker horseshoe-shaped central region and a brighter outer arc, a questionable amount of detail for that aperture. Joseph Winlock and George Searle, observing with the HCO 15-inch refractor around 1866, did not report the central star but "Two edges seen...as of a brighter nebula placed over a dimmer one. The brighter and fainter ellipses have major axes slightly differing in direction; the brighter having the position angle of its major axis 10° to 15° the large"
William Huggins first observed the emission line spectrum of NGC 7662 in 1864 and noted "three lines". It was confirmed by Father Angelo Secchi in 1866 and again by Lieutenant John Herschel, son of John Herschel, in 1868. At the time he was stationed in Bangalore, India for a trigonometric survey.
Barnard thought the central star was variable based on observations with the Yerkes 40-inch in 1897 and wrote a paper in 1908 on "The Variability of the Nucleus of the Planetary Nebula NGC 7662" (MNRAS, 68, 465). The paper includes a superb sketch made with the 40-inch refractor at Yerkes. In 1935, John Duncan wrote "The bright ring of NGC 7662, like that of NGC 6720, has a vivid bluish-green color; but the outer shell, seen with a large reflector [probably with the 60"] on a favorable night, has a pronounced reddish hue."
The nickname "Blue Snowball" is from Leland S. Copeland’s description "looking like light blue snowball" in a 1960 Sky & Tel article.

I thought the coil double in more closely upon itself than shown in Mr. Stoney's drawing, and that the central knot had a stellar nucleus.

Christian Peters discovered NGC 7688 on 13 Oct 1865 with the 13.5-inch refractor at Hamilton College in Clinton, New York, while searching for Biela's Comet (which never returned after 1852). Otto Struve independently discovered this galaxy a few months later on 12 Dec 1865 (also searching for the comet) with the 38-cm Merz & Mahler refractor at the Pulkovo Observatory outside St. Petersburg. Struve noted a mag 14 star in PA 201° at a separation of 80", which pins down this identification. Peters' discovery was not published until his 1882 list in Copernicus, so Dreyer credited Struve in the GC Supplement (6206). Both are listed in the NGC.

John Herschel made the single observation "eF; pL; forms a triangle with 2 st 10m, near it". Curiously, this object was not found on 4 attempts in 1856-57 with Lord Rosse's 72" and d'Arrest found it "hard to understand" (gloating?) after 2 successful observations at Copenhagen with the 11" refractor.

48" (11/4/21): at 375x, very bright and large, low surface brightness halo elongated nearly 3:2 N-S, ~3.5' in length. The northern halo just reaches a wide pair [24"] a mag 10/12 pair at the NNW end.
The galaxy is dominated by a very bright, well defined E-W bar, extending ~0.8'x15". A fairly low contrast, broad spiral arm is attached at the west end. It shoots south (perpendicular to the bar) a short distance and merges into the inner halo. Only the root of the eastern arm was seen. Although the two arms quickly become indistinct, they blend into a slightly enhanced glow surrounding the bar, forming an oval N-S ring (the bar defines the minor axis), with dimmer regions to the north and south of the bar!
24" (8/30/16): at 226x; bright, fairly large, dominated by a central bar extending at least 3:1 E-W, ~45"x15". A very low surface brightness arm is attached at the west end of the bar and extends to the south. The corresponding arm extending north on the east end was less obvious and only marginally glimpsed. The arms blend into a low surface brightness halo at least 2' in diameter. A nice mag 9.8/12 double star is off the NW side 2' from center.
13.1" (9/9/83): faint, moderately large, diffuse, elongated ~N-S. A pretty double star mag 9/11 at 24" is just off the north edge 2' from center and interferes with viewing.
William Herschel discovered NGC 7741 = H. II-208 = St. 12-95 on 10 Sep 1784 (sweep 264) and recorded "F, cL, R, brightest in the middle; the brightness diminishing by very gradual shades, sf a star (of the 10 or 11 magnitude by memory)." His position was too far 4' northwest. Heinrich d'Arrest observed the galaxy on 6 nights (first on 1 Sep 1864), noted the error in Herschel's position, and accurately measured the offset to the double star off the northwest side.
Édouard Stephan observed NGC 7741 on 2 Oct 1869, 27 Sep 1873 and 15 Sep 1876 (likely already aware). He measured an accurate micrometric position on 25 Oct 1881 with description "eF, fairly large, irr oval, elong E to W, two points of condensation." In the remarks section at the end of the his 12th discovery list, Stephan notes his entry was identical to GC 5005 [NGC 7741], but Herschel's position was poor. Perhaps while preparing his manuscript, he read d'Arrest's observations and added the comment or perhaps he inserted it in the table just to provide an accurate position. The 10 Dec 1873 observation at Birr Castle reads "cB, L, mE 108°, much diffused neby south and following, which Lord Rosse suspected to be divided into branching [spiral] arms." d'Arrest and Stephan were listed as "Other Observers" in the NGC.

William Herschel noticed NGC 7770 on 18 Sep 1784 (sweep 277) during his discovery of NGC 7771. He commented, "towards the sp part [of NGC 7771] seems to be a vS stellar nebula within the nebulosity of the large one, but it may be only a small star." Due to his uncertainty Caroline didn't assign NGC 7770 an internal discovery number and he did not receive later credit.
John Herschel discovered NGC 7770 again on 25 Aug 1827 while observing NGC 7771 (he was apparently already aware of its possible existence). His description from 25 Aug 1827 (sweep 91) reads, "pB; E; bM; has a vS almost stellar nebula about 45° sp, dist 40"." On the next night, he made a sketch and noted "... has a smaller neb, 60° sp, 35" dist." Wolfgang Steinicke mentions that John Herschel used object class "N2" (two nebulae), so it's surprising he didn't assign NGC 7770 a separate designation in his Slough or General Catalog. As a result, JH wasn't credited either in the GC or NGC.
Bindon Blood Stoney, Lord Rosse's assistant, discovered NGC 7770 again on 5 Nov 1850 while observing NGC 7769 and 7771. A diagram of the trio is in the 1861 publication (NGC 7770 is labeled Gamma). A more accurate sketch from 1855 is on plate V of the 1880 publication. Lord Rosse was credited with the discovery in the GC and NGC.

The "very small stellar nebula" is probably NGC 7770, though it wasn't catalogued separated. He observed NGC 7771 again on 13 Nov 1786 (sweep 635) and noted "cB, pL , lE, mbM." but missed NGC 7770.
John Herschel made two observations on 25 and 26 Aug 1827 (sweeps 91 and 92). In both observations he noted the small nebula (NGC 7770) on the SW side at a separation of 35" to 40".

We will check the possibility of a systematic error in other of Marth's positions measured on the same night.

48" (10/31/13): bright showpiece galaxy, very large, oval 3:2 E-W, ~7'x4.5', large bright core. Spiral structure was evident, though it was difficult to trace individual arms except for one better defined arm attached on the west side of the core. This arm sweeps towards the east on the south side of the core (~2' from center) and ends just east of center. The halo appeared lumpy with an irregular surface brightness and several HII knots/associations were visible. The brightest individual knot is [H69] #20 from Paul Hodge's 1969 paper "HII Regions in 20 Nearby Galaxies". This fairly faint, 10" knot was easily seen 1.5' S of center, near the south side of the halo. [H69] #27, a slightly smaller and fainter patch is near the west-northwest end of the halo (1.9' from center). On the west-southwest side of the halo were two additional close, faint knots, both ~8" in diameter; [H69] #32 situated 2.3' from center and [H69] #33 at 2.4' from center. Finally, [H69] #3/5 is a fairly faint, 15" patch near the northeast edge of the halo, 2.8' from center. A mag 12.5 star is just off the northern edge, 2.9' from center.
30" (10/15/15 - OzSky): at 303x; most of the detail seen in the 48" was visible, but the HII regions were not as obvious. The galaxy extended roughly 8' x 5' WNW-ESE and contained a relatively large core region that gradually brightened towards the center. Although the halo appeared mottled and ragged, spiral structure was subtle. A very low contrast "arm" extends due west on the northwest side of the core and another "arm" appeared to extend east on the southeast side of the core. I noted 4 HII regions: the most obvious is [H69] 20, a faint, 10" knot near the south edge of the halo, ~1.5' from center. [H69] 3/5, a larger, very diffuse isolated patch, perhaps 20" in size, was seen on the northeast edge of the halo, 2.9' from center. Closer to the core I noted two very low contrast knots, both ~8" in diameter. [H69] 11 is 1.3' NE of center and [H69] 10 is 1.2' E of center.

James Dunlop discovered NGC 7793 = D 608 = HN 4 on 14 Jul 1826 and recorded a "faint round nebula, about 2' diameter, with a very slight condensation towards the centre; a double star is north preceding" (2 observations). His position was 14' too far east (typical error) and the double star is probably a wide pair (~1' separation) about 8' N. Apparently John Herschel didn't observe this galaxy from South Africa.
George Bond independently found the galaxy on 7 Nov 1850 at Harvard College Observatory with a 4" comet-seeker and he announced it as a new discovery. Dreyer credited Bond with the discovery in the GC Supplement (6233) and the NGC. His RA was 40 seconds too large though he mentioned his position required further confirmation. An accurate position from the Cordoba D.M was stated in the IC 1 notes. Stephen O'Meara called NGC 7793 "Bond's Galaxy" in his book "Hidden Treasures", apparently unaware that Dunlop made the first observation.
NGC 7793 was first photographed at Harvard's Arequipa Station in Peru around 1900, but it was only described as a "* involved in circular nebula with nebulous dot." Based on a photograph taken with the 30" Reynolds reflector at the Helwan Observatory between 1912-14, Harold Knox-Shaw first identified this galaxy as an "open spiral, knotty and complex." A later plate revealed a "bright sharp stellar nucleus" and "very many knots and patches."

William Herschel discovered NGC 7810 = H. (III-984) = h2296 = Sw. 6-99 on 17 Nov 1784 (sweep 320), but the observation was very uncertain. He recorded, "suspected but 240x showed 2 small stars, and left it doubtful whether they contained nebulosity between them or not; rather against." He decided to not include this object in his three catalogues and Caroline crossed out the general (internal) discovery number 649 in her Sweep Observations. Her reduced position is just 1.5' too far N, so the identification is certain.
John Herschel made 3 observations, the first on 17 Oct 1785 (sweep 15): "Suspected nebula." Verified, being found in the middle of the field by setting the telescope on the place per working list [based on Caroline's Zone Catalogue, prepared for his sweeps]; but it so nearly a star as to be easily mistaken for the third star of a triangle." Since it was first noted by his father, he added the designation "H.MS [Herschel Manuscript]" and Dreyer called it "(III-984)" in the NGC to imply credit to William.
Lewis Swift independently found this galaxy on 5 Aug 1886 and recorded it as the 99th object in his 6th discovery list. Swift's position is 16 tsec too far west but his comment "2 F stars v near and in line with it" fits perfectly.

No structure was noted, although the glow seemed roughly circular. The small open cluster Be 59 is embedded on the NW side. This object may be NGC 7822 if John Herschel made a 1.5 degree error in declination.
John Herschel discovered NGC 7822 = h2302 on 16 Nov 1829 and recorded "the central part of what I am positive is an enormously L, but eF neb of a round figure, though I cannot trace its limits.

24" (10/12/20): NGC 7839 is a single mag 15.3 star located 5.4' SW of NGC 1. It was identified at 200x and also viewed at 375x. The appearance was completely stellar. A very nice 6" pair of 11th mag stars (uncataloged) lies 8' WSW.
Guillaume Bigourdan discovered NGC 7839 = Big. 102, along
with NGC 7833, on 18 Nov 1886. He
noted the size as 40"-50" with several points of
condensation." At his
position (just 5' southwest of NGC 1) is a mag 15 star (with a mag 17 star at
21" separation), though the fainter star is likely too faint to have been
seen in his 12-inch refractor. The

Located 4' NE of NGC 7837/7838 and 5' NNW of NGC 3. Incorrectly classified as nonexistent in the RNGC.
Albert Marth discovered NGC 7840 = m 600 on 29 Nov 1864 and noted "eF, S." The same night he discovered NGC's 7830, 7834, 7835, 7837, 7838, 3, 4. With the exception of NGC 7830, which is mostly likely a star, the other members can be confidently identified with faint galaxies. But there is no galaxy at his position for NGC 7840 and RNGC classifies the number as nonexistent.
