18" (9/6/10): this local group dwarf Irregular was
immediately picked up at 108x (without a printed finder chart) as a large, low
surface brightness hazy glow, ~4'x2.5', roughly elongated NW-SE, though the
outer extent increased with averted vision and careful viewing. A mag 12.7 star is superposed to the
southeast of center and a few stars are on the northwest end. The 1.5' region surrounding the mag 12.7
star is the brightest portion of the galaxy and the W and NW regions have a
very low surface brightness and appeared irregular and patchy. Located 12' NE of mag 7.3
Using 175x, a very small 15" knot was clearly visible about 50" following the mag 12.7 star. This knot is a giant HII region (site of violent starburst formation) catalogued by Hodge and Lee (1990) as HL 111. At 285x with direct vision a faint star at its west edge was similar in visibility, but with averted vision the HII knot was more evident. I probably viewed the brightest component 111c, which has a diameter of 11", of this HII complex. Two mag 10.5 stars 3.5' S and 5.5' S of the galaxy (part of the right triangle mentioned above) provide a useful guide to pinpoint the location of HL 111. The HII region is directly on a line and equally spaced with these stars -- just follow the stars to the small knot.

Several faint stars (besides the mag 13 star) are superimposed. Situated within a rich star field and appears similar to a low surface brightness emission or reflection nebula.

Lewis Swift discovered IC 10 = Sw. 7-1 on 8 Oct 1887 and recorded "F * involved in vL, eeeF nebulosity, eee difficult. In line with 2 stars of equal mag which with a 3rd forms a right angled triangle."
Nicholas Mayall first recognized IC 10 as a galaxy in 1935 ("An Extragalactic Object 3° from the Plane of the Galaxy" in PASP, 47, 317). In 1936, Hubble suggested it might be a member of the local group and called it "One of the most curious objects in the sky" in his 1936 classic "The Realm of the Nebulae." This wasn't confirmed until 1996 using Cepheid variables and the current distance estimate is ~2.5 million l.y. This irregular dwarf galaxy is probably a member of the M31 satellite system. It lies only 3.3° from the galactic plane and is the nearest starburst galaxy.

17.5" (8/5/97): position identified at 100x using a GSC chart, although only a couple of stars are plotted. Appears as a very faint circular glow with a couple of faint stars superimposed. Located 7' E of a wide pair of mag 9/11 stars [at 38" separation]. Does not resemble a cluster in appearance and would have otherwise thought this was a Milky Way patch. At 220x, the glow is ~4' in diameter and there are a sprinkling of ~10 very faint stars, mostly mag 14.5-15.5 with one mag 13 star. The glow has an irregular surface brightness with a mottled appearance and the periphery is not well defined.
William Denning discovered IC 166 around 1890 with his 10-inch With-Browning reflector. The discovery was communicated directly to Dreyer. The IC position corresponds with the faint open cluster Tombaugh 3.
Clyde Tombaugh independently found IC 166 in Jan/Feb of 1941 while surveying the circumpolar region from Lowell Observatory with the 13-inch Lowell telescope. He tentatively identified "Tombaugh 3" as an open cluster, though thought is might be a loose globular or "even a midget galaxy just beyond the border of our Milky Way System".

He measured the offsets for both objects correctly with respect to 10th magnitude BD +40°608. But he applied his RA (time) offset in the wrong direction for the western object, which he described as double. So the computed position for IC 258 is east of IC 259, placing these objects out of RA order in the sky.

The discovery was announced in a short note, "New nebula", Astronomy and Astro-Physics, 12, 189 (1893). He called it "rather faint, with nucleus about 12th magnitude, and very small, but it was sufficiently conspicuous to be discovered with a power of 40 only on my 10-inch reflector."

Lewis Swift independently found this galaxy on 23 Dec 1889 and reported Sw. 9-13 as "eeF; pL; R; passed in line with 1417-18; cometary; unable to refind it; seeing good. Failed also at Harvard College Observatory [during a visit]." Swift published a note in AN 126, 225 that "in description of nebula no. 13 for "passed" read "1st of 3". Calling attention to apparently so trivial a matter may seen unimportant, but it has more significance than at first sight appears, as I strongly suspect it to have been a comet, as at two subsequent examinations it could not be found. It was in in line with NGC 1417 and 1418 and all three were seen simultaneously." Swift gave an even more detailed review of this object in Astronomy and Astro-Physics (formerly Popular Astronomy, 11 (1892), so he clearly put a lot of effort and time on it. Frank Muller also found IC 344 in late 1887 while measuring positions for NGC 1417 and 1418. He described it as "round, diffuse" and gave a diameter of 1.0'. Dreyer credited both Herschel (h305) and Swift in the IC. Sherburne Burnham measured IC 344 (Publ of Lick Observatory, II) and correctly sorted out the confusion with JH's observation.

Herbert Howe suggested Muller's object was identical to Sw. 11-60 and Dreyer made the following note in the IC 2: "The place and description should be 03 35 26, 108° 43.0', eF, pL, E 80°, dif (my mistake). Is no doubt identical with Sw. XI 60; 03 35 13, 108° 39.8'." Dreyer gave no explanation of how the mistake was made, but perhaps he had meant to use Muller's observation instead or he noticed that Swift's observation closely matched Muller's. In any case, Dreyer's corrected position matches object #171 in the Leander-McCormick Southern Nebulae catalogue. Harold Corwin suggests that Stone's erroneous position for #151 may be due to a misidentified offset star.
Both Malcolm Thomson and Wolfgang Steinicke conclude that IC 346 should be classed as nonexistent based on the original IC data, leaving ESO 548-078 without an IC designation. See Courtney Seligman's analysis for more on this confusing situation.

The orientation was easy to judge using two 15th magnitude stars 1.8' S and 1.8' SSW of Merope and the elongated glow fell between the diffraction spikes. Despite the glare from Merope making the observation much more difficult, I was surprised this small reflection nebula was fairly bright and elongated (roughly pointing south from Merope) with a straighter western edge, perhaps 20"x10" in size.
E.E. Barnard discovered IC 349, a fan-shaped knot of nebulosity just 0.6' SSE of Merope, visually on 14 Nov 1890 using the Lick 36" refractor. It was announced in a discovery note in AN 3018. "On Nov. 14 while examining the cluster, I discovered a new and comparatively bright round cometary nebula close south and following Merope, every precaution was taken to prove that it was not a ghost of Merope by examining the other stars of the group under the same conditions. I have since seen it several times and on Dec. 8th I could see it with some difficulty in the 12-inch by occulting Merope with a wire in the eyepiece. With the great telescope the nebula can be seen fairly well with Merope in the field and is conspicuous when the star is placed just outside the north edge of the field. It is about 30" in diameter, of the 13th mag, gradually brighter in the middle, and very cometary in appearance. It was examined with powers of 300, 520 and 1500, with all of which it was comparatively easy."

E.E. Barnard discovered IC 356 on 23 Aug 1889 with the 12-inch refractor at Lick Observatory. His simple eyepiece sketch clearly identifies the neighboring stars. Barnard didn't publish his discovery until 1892 (AN 3097) in response to an independent discovery by William Denning on 7 Nov 1890 (Observatory, 15, 104 (1892)). Barnard's article was titled "Two Probably Variable Nebulae". In the article he mentions "from its brightness it is not possible that it has been so conspicuous for any great length of time, or it would surely have been found by Swift and others."
Both Barnard and Denning are credited in the IC. Denning was a bit peeved about Barnard's late discovery note and wrote "Mr. Barnard claims to have discovered [IC 356] in August 1889 whereas I did not pick it up until Nov 1890. While admitting this claim, I would venture to remark that anyone who makes a discovery ought to be prompt in announcing it, as a delay of several years is very likely to cause misconception and unnecessary trouble to others. I think that in ordinary cases priority of announcement ought to be accepted as priority of discovery." He also questioned Barnard's claim that the nebula had recent brightened, stating "I have picked up this object many times during the last two years without noticing any change in it other than can be fully accounted for by differences in atmospheric conditions."
But perhaps Barnard wasn't the first to discover this galaxy. Swift claimed (Astro-Physics, Vol XI, 566) an earlier discovery before 1879 based on marking the object on his Burritt's star atlas, though he didn't record or remember any particulars, stating he thought his early discoveries were all known!

Lewis Swift first discovered IC 359 = Sw. 2-29 = Sw. 10-14 on 20 Aug 1885 and reported "vF; pL; R; little brighter in the middle." His position is just 2.7' W (12 seconds of RA) of IC 359. He added a long note: "Resembles a Comet. Moonlight and clouds prevented verification until Sept. 6, when it could not be found. Am certain of its place, and of its configuration with 4 stars. Have examined the place three times and am certain of its absence. Seeing on one occasion as good as when discovered." He also stated in the introduction, "No. 19 [from list I] must therefore be struck out, and with great probability No. 29 of this Catalogue also."

E.E. Barnard discovered IC 361 on 10 Oct 1890 with the 6 1/2" refractor at Lick Observatory.

In 12-inch (175x) it is pL, excessively faint and seems to be an excessively faint cluster or extremely faint stars, with possibly some nebulosity - power too high." His simple sketch shows the cluster on line with two 6th magnitude stars to the southwest and the identity is certain. Barnard never published his discovery or notified Dreyer.
William Denning found it again on 11 Feb 1893 with his 10-inch reflector (see The Observatory, 41, 140). On 14 Sep he logged, "Cluster large and faint.

At 140x, the cluster consists of 40-50 stars including two mag 10 (the brightest is the wide double STF 707 = 9.7/11.4 at 18") and numerous mag 12-14 stars. With a UHC filter (or OIII filter at 100x), the cluster is encased in a moderately bright glow, ~8'x5'.

24" (2/23/22): at 375x; the bright central star was clearly surrounded by a sharply defined small ring with a dark rose color. Switching to 260x, the color was more evident and saturated.
48" (2/18/12): at 488x, the sharply defined, vivid raspberry annulus appeared relatively thin and extended NNW-SSE, ~14"x12". The high contrast central dark hole was striking surrounding the bright central star. Surrounding the annulus is a faint outer halo, increasing the size to roughly 20".
48" (4/2/11): truly impressive view at 375x and 488x, which revealed a very high surface brightness, slightly elongated halo, ~14"x12", surrounding the very bright central star. I was surprised to see the planetary was clearly annular with a very bright, irregular rim that varied slightly in thickness and a fairly high contrast darker hole surrounding the central star. The ring's outer rim was a shocking, deep raspberry color. The color was more intense at 375x and slightly more saturated along one-half of the annulus.
18" (1/26/09): striking view at 175x with the mag 10.5 central star blazing within a 10" disc with a crisply defined halo. Excellent contrast gain using an H-beta filter with the central star nearly lost with the high surface brightness disc. There appeared to be a very faint, thin envelope surrounding the main 10" disc extending a few arc seconds. At 285x, the planetary is slightly oval NNW-SSE with subtle variations in surface brightness; slightly weaker around the central star and slightly brighter along portions of the rim.
18" (1/15/07): at 115x, the bright mag 10.5 central star is surrounded by a small 10" disc with a noticeable raspberry tint.
17.5" (2/22/03): at 100x, the bright 10.5 magnitude central star was centered in a 10" round halo with a definite rosy or raspberry tint at the outer edge of the halo, though the effect is fairly subtle. Using an H-beta filter, the central star was strongly dimmed but the halo was significantly enhanced, dramatically changing the view of this planetary. At 380x, no color was visible but the halo was a bit asymmetrical with a "softer" edge and possible double shell structure. The center was very slightly darker around the central star.
17.5" (12/30/99): at 82x the mag 10.5 central star was enveloped in a very small round halo which appeared to have a slight reddish tinge at its edge. This is a low-excitation PN and using a H-beta filter, the halo brightened and the central star faded, leaving a more noticeable disc. At 220x, the prominent central star was surrounded by a well-defined 10" halo that partially "blinked" on and off switching from averted to direct vision. At 280x, the small halo was possibly surrounded by an extremely faint envelope, but this could not be confirmed. 380x and 500x presented a superb view of the inner disc which appeared weakly annular.
17.5" (3/8/97): unusually bright mag 10.5 central star surrounded by a small high surface brightness halo. At 220x, this planetary has a distinct "blinking" effect; staring at central star partially washes out the halo and with averted the halo is more dominant. At 82x, an unusual rosy tinge is evident at the edge of the small halo, although the effect was fairly subdued. The seeing was not steady enough for high power viewing of the outer shell.
17.5" (10/12/85): high surface brightness planetary, appears very bright at 481x. Contains a bright "fuzzy" central star with a bright inner portion surrounded by a second fainter shell slightly elongated N-S.
13.1" (10/20/84): very bright, small, takes 350-410x well, bright central star, subtle shell structure.
8" (2/23/22): at 95x, the PN was nearly stellar, appearing as fuzzy mag 10 star. Increasing to 176x, a small well-defined disc surrounded the bright central star. At 229x with a careful look, the halo could just be resolved as annular. A perfect very small ring!

Williamina Fleming discovered IC 418 on an objective-spectrum plate taken on 26 Mar 1891 (probably by Solon Bailey at Harvard's temporary station at Chosica, Peru or by William Pickering at Arequipa). In a note dated 20 Jun 1891 and published in Astronomische Nachricten 128, p.11, Mina described the H-beta line as "unusually large as compared with the line whose wavelength is 5007 [OIII], the visual spectrum differs strikingly from that of other planetary nebulae." Dreyer credited Pickering with the discovery in the IC.
W.W. Campbell, who credited Fleming with the discovery, made the first visual observation. In 1891 he reported "it is a beautiful object as seen in the 36-inch telescope [Lick], consisting of a 9th magnitude star surrounded by a circular disc of blue light nearly 15" in diameter."
Based on Crossley photographs, Curtis (1918) reported, "central star of mag 19, surrounded by a bright somewhat elliptical ring 14"x11" in outside diameter, and about 12"x10" along its central line; pa 163°." Walter Scott Houston made an observation in 1945 using a 10" reflector.
A star is plotted at this position on the Uranometria 2000.0 Atlas because the BD catalogue included the central star.

13.1" (1/11/86): using an H-beta filter IC 434 appears
a very faint, very large, very elongated strip of nebulosity running south of
Zeta Orionis for almost one degree in a N-S direction. There is a well-defined sharp edge
along the east side while the west side fades off into the background. Contains the famous dark nebula
24" (1/21/12): the view of the Horsehead through a 24" f/4.1 Starmaster using a Collins I3 image intensifier mated with a narrowband H-alpha filter at the Mauna Kea visitor center (9300') was absolutely stunning. The outline stood out in extremely sharp relief like a photograph and the dark cloud was pitch black against the bright background. I'm not sure of the magnification used but the field was 30' or less and the Horsehead was large enough to show exquisite detail in the outline.
17.5" (12/26/00 and 12/28/00): at 100x using an H-beta filter, the huge IC 434 strip was very prominent and easy to follow south from Zeta Orionis throughout the entire 50' field of view. The boundary was razor-sharp along its eastern edge against a background sky darkened by the H-beta filter. The Horsehead was very easy to view as a nearly black, semi-circular 4' indentation that protruded into the nebulosity. With averted vision there was a short extension or knob on the north side. This forms the snout of the horse and with concentration faint nebulosity is visible just below (east) of the snout.

Williamina Fleming discovered IC 434 on Harvard College Observatory plates in 1883. Edward Pickering announced the discovery (along with a number of other Orion nebulae) in the 1890 Harvard Annals publication (1890AnHar..18..113P). She also described the dark notch (later dubbed the "Horsehead") as "A large nebulosity extending nearly south the Zeta Orionis for about 60'. More intense and well marked on the following side with a semicircular indentation 5' in diameter 30' south of Zeta. All good plates of this region show this object, and it has been used here as a test for some time." Dreyer didn't mention the "indentation" in the IC description.
Harold Corwin comments that "Some people have suggested
that it was actually found by William Herschel. This is not true; WH's comment (see Latusseck, J. Astron.
Data 14, 4, 2008 where it is reprinted) "Wonderful black space included in
Nebulosities" refers to
But Wolfgang notes that on 1 Feb 1786 (sweep 518), Herschel recorded a large region of nebulosity extending roughly 2° north-south, not far east of IC 434. He noted "I am pretty sure the places of which these are the boundaries are all full of diffused milky nebulosity; but notwithstanding I used every means of ascertaining it by motion of the telescope, my range was neither far enough, nor sufficiently quick to put it beyond doubt. Caroline assigned it the general (internal) discovery number 1321, which became H. V 35 (first of 4 different fields associated with that designation). Wolfgang Steinicke feels it may apply to IC 434, though Herschel's RA is about 3 minutes too large, so this identification is very uncertain.

E.E. Barnard independently discovered these two nebulae in 1894. He reported in "Astronomy and Astro-Physics", Vol 8, No. 3, "On this same plate [taken on 1 Feb 1894 with a 2h 10m exposure] is a faint narrow curved nebulosity [IC 443] in about, 1860.0, 6h 8m + 23° 0'.

Max Wolf discovered IC 444, along with IC 443, on 25 Sep 1892 with a 2 1/4" lens. In AN 3130 (1892), he recorded finding "[Two] Very large and bright nebulous masses are visible there [near Mu and Eta Geminorum], which very roughly have their centers at approximately 6h 14m +24° [IC 444] and 6h 08m +22° [IC 443]."
E.E. Barnard independently discovered these two nebulae on a plate two years later. Barnard reported in "Astronomy and Astro-Physics", Vol 8, No. 3, "On another photograph taken Feb. 1, 1894, with 2h 10m exposure, the 9m.5 star Dm +23°1313 is found to be closely nebulous, a very small dense nebulosity gives it a fuzzy appearance. The nebulosity is heaviest south and following." Harold Corwin notes that Barnard misidentified the star -- it should be BD +23°1301 = 12 Geminorum. Secondly, his reported postion gave the equinox as 1885.0, but it should be 1855.0 for the BD star, so his position -- which was used in the IC -- is poor. Corwin also comments that although 12 Gem is often given for the position of IC 444, the reflection nebula is part of a much larger emission nebulosity (Sh 2-249) centered about 25' ESE. Wolf claimed to record "very large and bright nebulous masses", so perhaps his image included Sh 2-249.

Barnard mentioned that he first found it visually around 1888 "while sweeping over this region" as a "10 mag nebulous star about half a degree north preceding 2245."

E.E. Barnard visually discovered IC 447 = IC 2169, along with IC 446 = IC 2167, on 11 Oct 1888 with the 12-inch refractor at Lick Observatory. He noted "1 radius of 80x field [21'] south and 1 radius [21'] preceding the 7 1/2' m star [NGC 2245] is a large nebulosity, faint, that involves several 9 or 9 1/2 mag star. Nearly 1/2° in size, irregular(?)". His offset lands in the southern part of the nebula, though clearly he was referring the entire portion. He picked it up again on 26 Feb 1889 and logged "22' S and 22' p. the neb NGC 2245 is a vL neby, with some bright stars in it. It is extended N & S nearly, 15 x 12' +/- diam. There are 3 or 4 9th and 10th mag stars in a curve seemingly connected with it."
Barnard found this reflection nebula again photographically on 24 Jan 1894 with the Willard 6" lens though and announced it in "Photographic Nebulosities and Star Cluster Connected with the Milky Way" (Astronomy and Astrophysics, Vol XIII, No 3). Barnard stated he first found it visually around 1888 "while sweep over this region, I found a very large, weak, diffused nebulosity some half a degree south of the nebula NGC 2245. This was mixed up with several considerable stars." His earlier visual discovery was not published but apparently he sent it later to Dreyer, so it was catalogued again as IC 2169.
Barnard retracted his discovery of IC 447 in Lick Publications, Vol 11, incorrectly claiming it to be identical to NGC 2245. Hubble included this object in his 1922 paper "A general study of diffuse galactic nebula" in Contributions from the Mount Wilson Observatory / Carnegie Institution of Washington, vol. 241, pp.1-38.

Lewis Swift found IC 554 = Sw. 10A-1 on 28 Mar 1892 and recorded "eeF, eS, almost stellar." This was the first object in a short list of 8 nebulae published in MNRAS Vol. LIII, p.273, in his last year observing at the Warner Observatory in Rochester. There is nothing near his position, but 9' SSE is IC 555, which Stephane Javelle discovered just 6 nights earlier! So, it's reasonable to assume IC 554 is a duplicate observation of IC 555 given Swift's often poor positions in his later years. Courtney Seligman questions this identification due to the discrepant descriptions (Javelled called the galaxy "pretty bright"), but Javelle was using a much larger refractor.

This galaxy was probably discovered by William Herschel on 15 Mar 1784 and catalogued as H. III-34 (later NGC 2984), but his position was unusually poor -- 1 min 19 sec of RA west and 3.5' south of IC 556. Karl Reinmuth mentioned he couldn't find NGC 2984 in Dreyer's place using Heidelberg plates and questioned if it was equal to IC 556. This is likely the case as there are no other reasonable candidates for NGC 2984 in the vicinity. UGC, CGCG and MCG label this galaxy as IC 556 and RNGC calls it NGC 2984.

24" (4/14/18): at 282x and 375x; fairly faint, small, elongated 3:2 WNW-ESE. The twin nuclei (separation 13") of this merged double system were immediately resolved within a common halo. With careful viewing two overlapping haloes were visible, each ~15"-20" diameter. The nuclei are oriented NW and SE with the NW nucleus slightly brighter and clearly stellar. The eastern halo is possibly slightly larger and the nucleus was quasi-stellar. A mag 12.6 star is 1' WNW. Located 1.1° NW of mag 4.5 Alpha Sextans.
Stephane Javelle discovered IC 590 = J. 2-664 on 11 Mar 1893 and wrote "faint, diffuse, appears as a double star surrounded by nebulosity". Javelle's description implies he resolved both nuclei in this close double system.

David Todd discovered IC 669 = Todd 8 = J. 2-711 on 3 Dec 1877 during his search for a trans-Neptunian planet. He reported, "Object 'a' suspected -- it has a companion, [PA] = 25 [deg]." Harold Corwin states, "The companion is a star, and both are shown in his sketch which accurately reflects the sky."
Stephane Javelle independently made a secure discovery on 7 Apr 1893 and measured an accurate position. Javelle was credited with the discovery in the IC.

Francis Leavenworth found IC 714 = LM(S) 430 on 25 Feb 1887. He described it as "little extended 170°, gradually brighter middle nucleus." His micrometric position with respect to Theta Crateris matches NGC 3763 = PGC 35907. This galaxy was discovered by Andrew Common in 1880 and placed fairly accurately but neither Common nor Dreyer noticed the equivalence. So, NGC 3763 = IC 714.
