Wilhelm Tempel discovered IC 4173 = Big. 315 = NGC 4933sw around 1882 with the 11-inch "Amici I" refractor near Florence, Italy.  In his fifth discovery list, he described in the narrative portion, "In case of nebula NGC 4933 I made the remark years ago: certainly double, has a bright stellar nebula south preceding, 13m in the middle; the north following is large; Distance from each other a little over 1 '. A later remark is: fine elongated nebula with two knots, the brighter one north; on the southern tip of a faint stellar nebula"

 

Bigourdan independently resolved the two components (Big. 315 and 316) on 16 Apr 1895 while searching for NGC 4933, but he assumed these were new objects. Bigourdan is credited with the discovery in the IC.  See NGC 4933 for this story.  NED and MCG identifies the southwest component as NGC 4933A.

II-11 on 10 May 1899 and recorded "vF, S, mE 200¡."  His position matches PGC 51173.  Malcolm Thomson argues that this galaxy was the first of two discovered by Lewis Swift (IC 997 and 998), and hence should be identified as IC 997, but Harold Corwin disagrees.  See IC 997 for more.

22" (6/28/06 - Hawaii): fairly faint, large, edge-on 5:1 NW-SE, 3.5'x0.7'.  Fairly low even surface brightness with only a broad very concentration to a slightly brighter bulging core.  Faint stars at both the NW and SE ends of the galaxy and a string of 4 stars mag 13-14 begins at the star at the SE end and curves away from the galaxy towards the NE.

 

12.5" (6/24/06 - Haleakala Crater): at 180x, this edge-on appeared fairly faint, very elongated 5:1 NW-SE, ~3.5'x0.7', broad concentration to a bulging core.  Situated in a rich star field with a number of faint stars nearby including two mag 14 stars at the NW tip, a mag 13 star at off the SE end, a mag 14 star that is embedded just NW of the core and a mag 13.5 star off the NE side of the core.  Located 23' SE of mag 3.6 Iota Lupi.

 

18" (7/5/05 - Magellan Observatory, Australia): at 228x, this surprisingly bright and large IC galaxy seemed out of place in a very rich Lupus star field.  The galaxy is very elongated 5:1 NW-SE, 4'x0.8', with an irregular or mottled surface brightness (probably due to an equatorial dust lane which bisects the galaxy), though there was no visible core.  It nearly extends between a mag 13 star near the SE end and a pair of mag 14 stars just beyond the NE tip.  Located 6' NE of mag 9.4 HD 125568 and 23' SE of mag 3.6 Iota Lupi.

 

Royal H. Frost discovered IC 4402 = F. 1099 on 13 May 1904 at Harvard's Arequipa station.  He noted "Streak, 2.9' by 0.4' at 125¡, tapers to sharp points."

18" (7/5/05 - Magellan Observatory, Australia): at 228x, this is a very striking planetary with an unusual appearance.  The main body is bright and boxy, roughly 25" diameter with a bluish color.  A number of mag 14 stars appear to huddle around the planetary including a mag 13.5 star at the west end and some additional mag 13 stars are within 2'.  Much fainter extensions or wings are just visible extending E-W from the main body with the western wing slightly more prominent (though this may be due to the superimposed star).  The wings are more obvious when a UHC filter is used.  At 293x, there are three collinear stars just off the west edge with the western extension encompassing the closest star.  The wings increase the overall dimensions to ~60"x25".

 

13.1" (2/20/04 - Costa Rica): at 140x this bright bipolar planetary appeared fairly small, 20"-25" diameter with a high surface brightness and a bluish color.  The outline is unusual, appearing somewhat boxy or rectangular in appearance.  A faint star is just off the west edge.  At 195x there appeared to be very faint extensions ~E-W, increasing the dimensions to 2:1.

 

13.1" (3/17/86): fairly bright and prominent with a Daystar 300 filter although viewed at a low elevation.  Fairly small, 35" diameter, smooth disc.  Visually appeared almost round although photos reveal a very elongated shape.  No central star seen at 214x.  A mag 13.5 star is just off the west edge.

 

13.1" (6/18/85): viewed for 1-2 minutes as it appeared and disappeared just east of Fremont Peak from Coulter Row.  Appeared fairly bright and fairly small and roundish.

 

DeLisle Stewart discovered IC 4406 = D.S. 406 = Fleming 94 on a plate taken in 1899 at Harvard's Arequipa Station.  He noted "2 nebulous stars make dumb-bell, remarkable."  Williamina Fleming found it again in 1901 on a Harvard objective prism plate at Arequipa.  Finally, Robert Innes independently found it again while observing with the 7-inch Metz refractor of the Royal Observatory at the Cape of Good Hope.  He wrote, "As seen with the 7-inch on 14 August 1901 this is a fine planetary nebula, 10th magnitude, about 20" in diameter. Examined on the same night with the 18-inch telescope, it appears dumb-bell-shaped..."  Perhaps surprisingly, this fairly bright planetary was missed by Dunlop and John Herschel.

Stephane Javelle discovered IC 4461 = J. 1326, along with IC 4462 = J. 1327, on 22 Jun 1895.  There are 3 galaxies (VV 303) nearby, but his micrometric position for J. 1326 matches VV 303c = MCG +05-34-076 = PGC 52120 and his position for J. 1327 matches VV 303a = MCG +05-34-077 = PGC 52119.  This implies the Javelle missed VV 303b = MCG +05-34-078 = PGC 52123.  NED (now corrected as of 2015), PGC and HyperLeda misidentifies PGC 52119 as IC 4461 and PGC 52123 as IC 4462.  I notified Harold Corwin, Malcolm Thomson and Wolfgang Steinicke of my conclusions and they concur with my identifications.

17.5" (6/24/95): very faint, very small, round.  There is a mag 14.5 star just off the NE side 21" from center which confused the observation.  At moments, the compact core of the galaxy and the star appeared to form a faint double star.  I missed the faint extensions (arm) E-W on the POSS.  Forms a pair with NGC 5712 4.0' ESE.

 

Guillaume Bigourdan found IC 4470 = Big. 421 on 11 Jul 1887.  His full description (from Corwin) reads "Object which, at first sight, could be nebulous, but in which I suspect several stellar points.  It is therefore a cluster enveloped in nebulosity; it is vaguely elongated at 90 degrees and is 1' l and 40" wide."  His position is within 1' of CGCG 353-040 = PGC 51696.

 

While working through CH's 1802 "Fair Copy" of WH's sweeps on 10 Jun 2014, I found WH discovered this edge-on galaxy during his observation of H III-950 = NGC 5712 on 20 Dec 1797 (sweep 1074): "It is preceded by a small patch of stars which appears almost like this nebula, but more resolved."  This sounds very similar to Bigourdan's description and certainly applies to IC 4470 (Harold Corwin and Wolfgang Steinicke concur).  Wolfgang included it in his "WH Special" list of 22 Jun 2014.

E.E. Barnard discovered IC 4572 = J. 3-1380 visually, probably along with IC 4569, on 29 Jan 1889 with the 12-inch refractor at Lick Observatory.  His position of 15h 36m 53s +28¡ 25' (1889) corresponds with a group of IC galaxies (IC 4568, 4569, 4570, 4572, 4574), but is closest to IC 4572 and IC 4570.  The southeast galaxy on his simple sketch (probably IC 4572) is noted as "pF, pL, gbM, Rndish."  The northwest galaxy (either IC 4570 or IC 4569) is noted as "pS, gbM, Rndish."  The sketch of the 80x field shows a single star - probably mag 8.4 SAO 83949 = HD 140253.  If the field diameter is close to 40', then the second galaxy is more likely IC 4569 (separation of 17'), which has a higher surface brightness and was more evident in my visual observation.

 

Stephane Javelle found this galaxy again on 25 Jul 1895 with the 30-inch refractor at the Nice Observatory and measured an accurate position.  Barnard didn't publish his discovery or notify Dreyer directly so Javelle is credited with the discovery in the IC.

18" (7/12/10): immediately noticed at 108x while viewing Barnard 41 (about 15' NE).  This large reflection nebula (part of Rho Ophiuchi complex) contains two bright, striking pairs at 47" (SHJ 225 = 7.4/8.1) and 13" (SHJ 226 = 7.6/8.4).  Both of these pairs are encased within a large, obvious hazy glow with an irregular, elongated shape oriented NW-SE.  The glow was faintly visible in my 80mm finder at 13x.

 

13.1" (7/5/83): appears as a large, slightly milky and starless region involving two pretty double stars (SHJ 225 = 7.4/8.1 at 47" and SHJ 226 = 7.6/8.3 at 13") and a single star to the west.  This triangular region appears "lighter" than the surrounding background with a Deep Sky filter.  The north side has a more definite edge.

 

E.E.

17.5" (6/30/00): this is a large, circular glow surrounding a 4' pair of mag 8/10 stars and is part of the Rho Ophiuchi complex (2¡ north of Antares).  The nebulosity extends roughly 8'-10' in diameter.  The setting is quite eerie as the 50' field is nearly devoid of all stars - just two other faint stars and the field has a dull gray appearance as if it was weakly luminous.

 

E.E. Barnard visually discovered IC 4603, along with IC 4604, around 1883, probably with his 5" refractor.  In his 1895 paper "On a great photographic nebula near Antares", he stated "for fully ten or twelve years I have known of a vast region of nebulosity in Scorpius near Antares."  In addition he referred to a note made 15 June 1892, "A couple of years ago [at Lick Observatory] I found 2 stars involved in a very large diffused nebulosity.  They are strongly nebulous in the 6.5" and in the 12", but are best seen in the 6.5".  The stars are about 8.5 and 9.5 mag, the following star being the brighter.  They are 1.8¡ north and 42' preceding Antares [apparently IC 4603].  This region and preceding it for some distance seems to consist of a vast but very diffused nebulosity."  At Lick he took an image of region on 23 Mar 1895 with the 6" Willard lens at Lick Observatory. He noted "the brighter and more complicated portions of the nebula center about Rho Ophiuchi, 22 Scorpii and a couple of small stars occupying the center of the equilateral triangle formed by Rho Oph, 22 and Sigma Scorpii."  The "couple of small stars occupying the center" are involved with IC 4603.

E.E. Barnard visually discovered IC 4604, the Rho Ophiuchi Nebula, around 1883, probably with his 5" refractor.  See notes on IC 4603.

 

Caroline Herschel, in a letter to her son John, mentioned she "once heard your father, after a long awful silence, exclaim "Hier ist wahrhaftig ein Loch im Himmel! [Here is truly a hole in the heavens!]".  She urged John to search for region in the lower part of Scorpion as William returned to it several nights over several years.  In Joseph Ashbrook's "Astronomical Scrapbook", he concludes this remark apparently refers to the Rho Ophiuchi region, although an internet search shows the quote is sometimes attributed to Barnard 86.

E.E. Barnard discovered IC 4605 on a plate taken 23 Mar 1895 with the 6" Willard lens at Lick Observatory.  It's possible he discovered it visually (along with IC 4603 and 4604) as early as 1882 or 1883 with his 5" refractor, although he only claimed "for fully 10 or 12 years [before 1895] I have known of a vast region of nebulosity in Scorpius near Antares.

17.5" (7/16/88): marginal object, very small, elongated SSW-NNE, mag 14 star close following.

 

17.5" (8/21/87): extremely faint, very small streak oriented SW-NE.  Located just west of a mag 14 star that forms one vertex of a small trapezoid of mag 14 stars.  Only visible part of the time (~20%) with averted.

 

E.E. Barnard discovered IC 4617 and communicated the discovery directly to Dreyer (date and instrument unknown).  His RA is 50 seconds too small but this galaxy clearly matches the description "S, E 29¡, bM".

18" (6/12/10): this large HII region is embedded in the northern half of Tr 24, a sprawling 60' cluster just north of NGC 6231.  At 108x and UHC filter IC 4628 stood out as a very large, fairly bright glow within Tr 24.  The main glow was elongated E-W, roughly 30'x12' with mag 7.2 HD 152723 just off the south side.  The northern side has a fairly well-defined edge and a number of mag 8-10 stars are embedded along the southwest and west end of the nebulosity.  A fainter extension begins on the east end and extends northeast for ~15', ending in a brighter HII patch (G345.31+01.47) peppered with several stars and involving the infrared cluster [DBS2003] 114.

 

8" (7/13/91 - Southern Baja): this is an emission nebula on the north side of a large open cluster Tr 24 = H12.  Appears fairly faint, very large, about 30'x10' diameter and clearly elongated E-W.  Shows up best with the UHC filter at 83x although visible without a filter.  Includes some brighter portions.  Also visible in the 16x80 finder with a UHC filter.

 

E.E. Barnard discovered IC 4628 between 1892 and 1895 on a plate taken at Lick Observatory.  In Lick Publications Vol 11, 1913, Plate 37 he describes: "The coarse cluster in 16h 48m, -40.3¡ does not seem to be in Dreyer's lists.  It is a very interesting objects and appears to be connected by a scattering chain of stars, with the cluster [NGC] 6231 south of it.  In its northern part is the nebula IC 4628.  This was originally discovered on a plate with the Willard lens, but no announcement was made of it.  It is a large nebula one half degree in diameter and of irregular form and brightness.  A photograph with the 10-inch Bruce telescope at Mount Wilson in 1905 (June 21) shows the irregular group of stars and the nebula very beautifully.  There are still fainter portions that extend half a degree to the northeast.  The nebulosity, apparently, does not condense about any one of the stars and is probably not actually connected with the cluster."  Royal Harwood Frost also found IC 4628 = F. 1148 on a photographic place taken in 1903 at Harvard's Arequipa station and both are credited in the IC.

24" (7/14/15): at 375x, fairly faint, small, slightly elongated N-S, ~22"x16".  Contains a bright stellar or quasi-stellar nucleus.  I had a couple of definite "pops" of the tidal tail extending to the south.

 

24" (7/24/14): at 375x, this post-merger system appeared fairly faint, fairly small, slightly elongated N-S, 0.4'x0.3'.  Strongly concentrated with a very small bright core containing very bright, sharp stellar nucleus.  With careful viewing, there was a very strong impression of an extension (tidal plume) extending south.  The narrow tidal tail extending northeast on the SDSS image was not seen.

 

18" (7/12/10): faint, fairly small, elongated 3:2 ~N-S, 0.6'x0.4'.  Sharply concentrated with a very small bright core.  Forms the vertex of a flat isosceles triangle with a mag 10 star 4.4' SSW and another mag 10 stars a similar distance northeast.

18" (7/22/06): picked up at 225x as a bright, small, blue disc of very high surface brightness.  Good contrast gain using the UHC filter.  Appears much brighter than the similar mag 11 star using the filter.  At 435x, the planetary is slightly elongated N-S, ~10"x8" with strong flash of a central star.  There appears to be a much fainter, very thin envelope encasing the high surface brightness disc.  Similar view at 565x though the elongation was clearer and the outer envelope increased in size to ~15"x11".

11" (8/8/04 - Haleakala Crater): first noticed in 10x30 IS binoculars while looking at NGC 6352 as an obvious knot 1.5 degrees to the south.  At 127x, I was surprised to find a beautifully rich open cluster with over 100 stars mag 10-13.5 in at least a 15' field.  The stars are fairly uniform in distribution with a weak central concentration, though several form loops and chains around blank areas.  The brightest mag 9 star is on the east side. This is an intermediate-age cluster (~2 billion years old).  Located one degree west of mag 2.8 Alpha Arae.

 

James Dunlop discovered IC 4651= D 402 on 28 Jul 1826 and described "a very fine round cluster of very small stars, slightly compressed to the centre, about 8' diameter."  His position is on the south side of the cluster, so the identification is certain.

 

Solon Bailey rediscovered the cluster on a photographic plate in 1896 using a 1" lens at the Arequipa station.  The discovery was reported in "A Catalogue of Bright Clusters and Nebulae" (Annals of Harvard College Observatory, Vol LX, No. VIII, 1908).  Bailey was credited with the discovery in the IC as John Herschel didn't confirm Dunlop's observation.

18" (7/8/02 - Magellan Observatory, Australia): at 171x, this irregular galaxy has a disrupted appearance or perhaps is interacting with a companion.  The structure is difficult to separate but the brighter component on the northeast side is moderately bright, small, elongated WNW-ESE.  Attached on the south side is a larger, but fainter extension oriented nearly perpendicular to the brighter component.  A faint star is at the edge.  IC 4662 is located just 10' NE of mag 3.7 Eta Pavonis and the bright star interferes with viewing if left in the field.

 

According to the article "Star formation in the irregular galaxy IC 4662" (A&A, 1990, 234, 99) the elongated knot on the northeast side contains two giant HII regions comparable to the 30 Doradus complex!  IC 4662 is identical to He 2-269 (PK 328-17.1), which Karl Henize included in a 1967 list of planetary nebulae discovered through H-alpha emission on objective prism plates.  In a 1970 paper, Pastoriza gave the classification as a nearby dwarf emission line galaxy with a radial velocity of ~400 km/sec (less than 10 million l.y.).

 

Robert Innes discovered IC 4662 visually in 1901 with the 7-inch Merz refractor at the Cape of Good Hope.  He noted "a faint oval nebula 1' in diameter, N.p. Eta Pavonis.  Found with the 7-inch."  Based on plates taken at Arequipa, DeLisle Stewart noted "F, S, irr, 2 st. inv."  Stewart referenced Innes' discovery announcement in MN 62, 470.

Joseph Lunt discovered IC 4670 visually in 1901 with the Cape Observatory 24-inch refractor (the "Victoria Spectroscopic Telescope" erected in 1898) fitted with an object-glass prism.  He described it was stellar and mag 12-13 and situated "immediately S.f.

48" (4/1/11): IC 4677 appeared as a prominent, triangular or wedge-shaped knot with the vertex pointing east, situated 1.8' due west of center near the edge of the outer halo. It appeared much larger than previously seen, ~50"x30", and brighter along a well-defined, straight southern edge.  The north side is brightest near the east end at the vertex.  A 15th magnitude star lies 45" NE and a mag 9.8 star is 1.2' NW.  A second fainter (uncatalogued) knot in the outer halo is located 2.6' ESE of center, just 30" N of a mag 14.5 star.  This knot was only 15"-20" in size and had a low surface brightness.

 

18" (6/20/04): easily visible at 160x using a UHC filter as a slightly elongated, low surface brightness glow 1.7' W of center of NGC 6543 and 1.5' SE of a mag 11 star which lies 2.7' WNW of NGC 6543.  This shock-excited knot in the outer halo was elongated 3:2 SW-NE, roughly 20"x13".  At 225x it was barely visible unfiltered, but could be held continuously at this power adding a UHC filter.

 

17.5" (6/3/00): at 140x with a UHC filter, this ionized knot in the outer halo of the Cat's Eye was faint but clearly visible as a low surface brightness arc, located just south of the midpoint of the line connecting the geometric center of the PN with a mag 11 star 2.7' NW.

 

17.5" (11/1/97): this unusual object is a irregular knot in the outer halo of NGC 6543 1.7' W of center and appearing visually completely detached from the bright planetary.  Suspected at 220x without filtration close to a mag 15 star located 1' NW of the planetary.  Using a UHC filter, IC 4677 is clearly visible with averted vision as a very faint elongated patch, ~25"x15" oriented SW-NE.  Requires averted for a good view but can almost hold continuously.  Also visible at 140x with OIII filter and 280x with the UHC, but 220x provided the best view.

 

E.E. Barnard discovered IC 4677 on 24 Apr 1900 with the 40-inch Yerkes refractor.  Harold Corwin comments that Vorontsov-Velyaminov "included it in his first list [1959] of interacting galaxies (where it is No. 121), and in the MCG (it is MCG +11-22-017).  This is a bit surprising as VV was an early authority on planetary nebulae; his book from the 1930's is now something of a classic on the topic.  Still, the object does look something like a distorted late barred spiral on the PSS prints."  IC 4677 is now known to be a shock-excited knot (or FLIER) in the halo of IC 4677.

17.5" (7/20/96): at 82x, very subtle glow around a pair of mag 8.5/10 stars.  Somewhat difficult at low power to identify with certainty due to location in a rich Milky Way field and the nearby nebulous glow from M8.  Better at 140x-220x, where a fairly obvious 3' glow is visible.  No noticeable improvement with filters.

 

17.5" (6/8/96): at 220x a low surface brightness halo of 3' diameter is visible around a pair of mag 8/9 stars at 50" separation.  Very weak if any enhancement with OIII filter (reflection nebula?).  On photos the nebula is centered on the fainter SW mag 9 star.

 

E.E. Barnard discovered IC 4678 photographically using the 10-inch Bruce telescope at Mt. Wilson in July 1905. In describing the region surrounding M8 (see AN 4239), he mentions "There is a small, elongated nebula in the position 1860.0 17h 59m 25s± -23d 53m±".  Although there is nothing at that location, Harold Corwin suggests this refers to a small nebula northeast of M8, located about 1.5 min of RA west of Barnard's position, and centered at 18 06 32.3 -23 57 31.  See Corwin's notes.

In describing the region surrounding M8 (see AN 4239), he mentions "There is a conspicuous, small nebula or nebulous star in the position 1860.0 18h 0m 35s± -23¡ 26'±."  His position is close north of the double star mentioned in my observation.

13.1" (8/17/85): a thin dark "finger" extends towards the cluster, positioned just south and beyond the two bright mag 9 stars near the center.  This is an extension of the wider projection seen previously several times and which is better defined along the south edge.

 

13.1" (8/15/82): the "Eagle Nebula" is a fairly bright 30' nebulosity in a striking outstretched eagle shape with a bright scattered cluster superimposed.  There is a considerable contrast gain to the nebulosity using a UHC or OIII filter.  With a UHC filter, a dark projection (called the "Star Queen") enters on the southeast edge of the nebula and extends inward to the west. The cluster members surrounding the "head" of the eagle include ten mag 8-10 stars and a bright pair of mag 8.5 stars (8.2/8.8 at 27").  A dark triangular wedge is visible off the north side.

 

13.1" (5/26/84): the dark protrusion was fairly easy at 88x.

 

Isaac Roberts found IC 4703, the nebulosity involved in M16, on a photograph taken with his 20" reflector in 1894.  Although De ChŽseaux discovered M16 between 1745-46, he only mentioned a star cluster and even William Herschel just described the stars using his 12-inch reflector: "Large stars with small ones among them; within a small compass I counted more than 50, and there must be at least 100 without taking a number of straggling ones, everywhere dispersed in the neighborhood."  Roberts is credited with the discovery in the IC, but Steinicke notes in his book on the history of the NGC that Etienne Trouvelot made a visual discovery in 1876 with the USNO 26-inch refractor.  Trouvelot mentions "..described by Sir J. Herschel as a loose cluster of at least 100 stars, I have found to be involved in an extensive, although not very bright, nebula, which seems to have escaped his scrutiny.  In a study and drawing of this nebula made in 1876, its general form is that of an open fan, with the exception that handle is wanting, with deeply indented branches on the preceding side, where the brightest stars of the cluster are grouped.  From this peculiar form, this object might be appropriately be called the Fan Nebula."

E.E. Barnard discovered IC 4706 and 4707 photographically in Jul/Aug 1905  using the 10-inch Bruce telescope at Mt.

Charles Messier "discovered" M24 = "Small Sagittarius Star Cloud" = IC 4715  telescopically on 20 Jun 1764, although it is of course a prominent naked-eye object.  E.E. Barnard photographed the region in 1905 and described in AN 4239 ("Some notes on nebulae and nebulosities"), "The magnificent star cloud...is remarkable for the definiteness and angularity of its south and following outlines.  The east side is about 42' long and is very straight.  The south side is somewhat irregular and much longer.  The run south preceding for about 90' and then joins the great bed of nebulous matter just described.  The northern edge of this star cloud is diffused.  In the cloud towards its northern edge, are two remarkable black holes..."   His position, though, was 10 min of RA too large, so Dreyer didn't recognize it as M24.  Brent Archinal caught the error and made the equivalence (see Corwin's identification notes).  WH apparently first observed M24 on 2 Aug 1783 with his 12-inch and noted "considerable stars in great number."  JH lists his cluster h2004 = NGC 6603 as M24, so he didn't realize the Messier entry applied to the entire star cloud, not the small embedded cluster.

Burnham's "Celestial Handbook", MOL (Master Optical List) and the NGC 2000.0 catalogue (Sinnott) misclassify this galaxy as a planetary nebula.

The first and most famous in this paper being the "Fine Ring Nebula" Shapley 1 in Norma and this object is Shapley 5.  Evans and Thackeray (1950) state "We find (Plate II, Fig. 20) a curious round object of diameter about 19" with three distinct nuclei running along a north-south line across it. The designation as a planetary again seems doubtful."  Perek and Kohoutek rejected the PN classification in the 1967 Catalogue of Galactic Planetary Nebulae with the comments "Not a planetary", Henize, private communication; "doubtful planetary", Evans, Thackeray, 1950.

17.5" (8/2/97): this galaxy is located just 2.0' following a mag 6 star (HD 174262) and the view is severely hampered by the bright star!  At 220x, this object is visible as a very faint and small, round disc, ~15" in diameter.  A better view was at 420x with the 4.8 Nagler where the unconcentrated galaxy is well separated from the bright star.  When the bright star exited the field the galaxy was quite easy to view due to its relatively high surface brightness.

 

Sherbourne Burnham discovered IC 4791 visually on 4 Jun 1889 with the 36-inch Lick refractor.  Burnham measured micrometric offsets from the nearby bright star (Lalande 35032 = HD 174262) in 1899 at Yerkes (Publ of Yerkes Obs, Vol 1, p296). 

 

On the DSS, this object appears to be a fairly bright compact galaxy (confirmed by Brian Skiff on POSS 2), though it is not listed in any modern catalogue except for LEDA 1588608. The IC description "Neb;* 6 f 2Õ" should read "* 6 p 2Õ".

Lewis Swift discovered IC 4991 = Sw XI-191 on 23 Sep 1897 and reported, "vF; cS; R; no bright star near".  There is nothing near his position.  The nearest bright galaxy is ESO 340-011, identified as IC 4991 in the ESO-Uppsala catalogue (and followed by PGC, RC3, NED, NGC 2000.0 etc.).  This galaxy is located 32' north of Swift's position and 37 seconds of RA east.  But a mag 9.5 star is 5' NW as well as a mag 8.3 star less than 9' N.  Although Swift's positions are notoriously poor in his final observing years, the two bright nearby stars in his field  makes this identification unlikely.  Still it is certainly bright enough to have been picked up by Swift, so it remains a possibility.

William Herschel discovered IC 4996 on 20 Sep 1786 (sweep 594) and recorded, "Clustering stars the place taken is pretty much condensed, and contains 3 pS stars close together".  He didn't assign an internal discovery number or H-designation, so this observation went unpublished, but Wolfgang Steinicke found that his offset in time and PD from 6th magnitude 34 Cygni (the next object in the sweep) matches this cluster.  Steinicke also notes that soon after in the sweep he encountered M29, and just noted a "Clustering large stars" again without assigning a number.

 

According to Wolfgang Steinicke, Hugo Clemens "noticed the object on a plate taken [13 Jun 1896] for the Photographische Himmelskarte with an 10.5" f/10.5 astrograph at Potsdam Observatory."  The IC credit went to Frank Bellamy, who independently discovered IC 4996 on a plate taken 13 Jun 1896 with the 13" astrograph at Radcliff Observatory in Oxford.  The discovery was announced in the paper "A New Cluster in Cygnus", MNRAS 64, 662 (1904).  Bellamy didn't state a position for the cluster in the paper, but Dreyer's estimated position is ~25'  too far north.

Lewis Swift found IC 5039 = Sw XI-197, along with IC 5041 = Sw XI-199, on 29 Aug 1897 and recorded "vF; pS; R; 2 F st near nf point to it; 1st of 3."  His position for IC 5039 is 17 seconds of RA west of ESO 463-020 = PGC 65249 and that of IC 5041 is 2.5' N of ESO 463-021 = PGC 65258.  Remarkably, this was the 3rd out of 4 times he "discovered" this pair in the summer of 1897 at the age of 77.  His first observation of the pair, Sw XI-100 (later IC 5046) and Sw XI-101 (later IC 5047) was on 9 Jun 1897.  IC 5046 was described as "eF; pS; vE; eeF * and vF * near sf, point to it; sp of 2.", while IC 5047 says "eeF; pS; vE; 8m * 31' n; v diff; nf of 2."  His RA for both are about 1.5 minutes too large and his dec is 3' too far south, but his description fits.  He found the pair again on 26 Jul 1897 and recorded Sw XII-22 (later IC 5029) and Sw XII-23 (later IC 5030), but his RA was 3 minutes too small, and the dec for IC 5030 10' too far south.  The 4th observation was recorded as Sw XII-18 (later IC 5003) and XII-19 (later IC 5007) on 8 Sep 1897 and this time his RA was 18 minutes too small!  Once again, the description of the field clinches this identification (uncovered by Harold Corwin).  As a result, IC 5003 = IC 5029 = IC 5039 = IC 5046 and IC 5007 = IC 5030 = IC 5041 = IC 5047.  The IC positions for 5039 and 5041 are from Howe and very accurate, though IC 5046 and 5047 refer to Swift's first observation of the pair.

18" (9/25/06): I viewed the IC 5068 complex using a 20mm Nagler (113x) with an OIII filter or UHC filter.  To the northwest of IC 5068 is an obvious second large patch of nebulosity that is generally designated IC 5068B (though possibly equal to IC 5067).  This piece is very large and elongated NW to SE, extending perhaps 40'x15'.  It contains a bright circular 10' patch to the south of mag 8.2 SAO 50061.  A broad river of faint nebulosity streams away towards the northwest from this brighter region.

 

Thomas Espin discovered IC 5067 visually, along with IC 5068 and 5070, on 7 Sep 1899 with his 17 1/4-inch reflector. He simply noted "faint" and there is nothing at his position, about 37' W of the neck of the Pelican Nebula (IC 5070).  Harold Corwin suggests that if Espin's declination was off by 1.5¡, then IC 5067 corresponds with IC 5068B, described here.  Espin's positions for IC 5068 and 5070 are good, so IC 5067 is lost without additional information, but Corwin notes that IC 5068B is the brightest nebula in the region that he might have picked up.

18" (9/25/06): IC 5068 is the second of three very large emission nebulae roughly one degree south of the southern end of the Pelican Nebula.  At 113x and an OIII filter, this object appears very large, diffuse, irregular glow, roughly 25'x20'.  It is noticeably brighter in a 12' circular region about 10' N of a mag 7.3 star (HD 198690) and a group of brighter stars that are near the southeast side of the nebula.

 

To the northwest is a second large patch of nebulosity, generally designated IC 5068B, though if Espin's declination was off by 1.5¡, this may be IC 5067.  This piece is very large and elongated NW to SE, extending perhaps 40'x15'.  It contains a bright circular 10' patch to the south of a mag 8 star (SAO 50061).  A broad river of faint nebulosity streams away towards the northwest from this brighter region.

 

To the east of IC 5068 is the least conspicuous section, dubbed IC 5068C.  This detached piece extends 30'x15' (elongated E-W) and overall has a low surface brightness appearing as a hazy glow.  A mag 6.7 star is at the southwest end and a mag 7 star is at the eastern edge.

 

Reverend Thomas Espin discovered IC 5068, along with IC 5070, visually on 7 Sep 1899 with a 17 1/4-inch reflector at his Tow Law observatory in England. He simply noted "very faint", but his position is only 6' NW of center of this very large, parallelogram-shaped nebula, so the identification is fairly certain.

 

Discovered by Espin (AN 3633).  Described simply as "very faint".  The Pelican Nebula is also announced in this short list of 6 objects.  His discovery position is 1 tmin W of the Sky Catalogue 2000.0 position!

18" (7/17/07): The huge Pelican Nebula overfilled the 67' field in the 31 Nagler.  The UHC filter gave a higher contrast than the OIII filter.  Several brighter sections were noted on the close-up chart A1 in the U2000 atlas.  One of the brightest pieces is the "neck" of the Pelican located 20'-25' W of mag 4.8 57 Cygni and collinear with two mag 8/9 stars 10' and 12' due west.  The glow extends 10' in length.  To the SW of the mag 4.8 star is the large "beak" section that streams from NW to SE and extends roughly 20'x8', widening a bit at the SE end.  The west side of the beak is defined by a dark lane that parallels the nebulosity and the large, faint body of the Pelican is west of this lane and includes 5.1-magnitude 56 Cygni (the nebulosity is very weak here).  The brightest section of the body is a large, circular patch at the south end, ~12' diameter, and located 30' SE of 56 Cygni and 55' S of the "neck".

 

18" (9/25/06): This was the first observation of the Pelican Nebula in quite awhile and I forgot about this huge, interesting emission nebula.  The view was fascinating at 113x with an OIII or UHC filter as this object overfilled the 44' field.  I started exploring to the west of 4.8-magnitude 57 Cygni.  The brightest section is possibly on a line with this star and a mag 7.2 star further east and corresponds with the neck portion on the Pelican.  This is where the ionization front is most evident on photographs.  The elongated "beak" of the Pelican also begins to the west of the bright star and streams off in a wide river of nebulosity towards the southeast and passing out of the field.  A long darker lane apparently free of nebulosity isolates the "neck" from the main body of the Pelican.  The irregular body spreads out to the south of the neck well beyond the southern edge of the eyepiece field and extends at least 65' from the neck terminating at the SE end with a roundish bright patch of nebulosity ~12' in diameter.  The Pelican is located directly west of the North American Nebula and part of the same huge complex of nebulosity in this region (separated by the dark cloud LDN 935).

 

13.1" (7/5/83): the entire body of the "Pelican" is easily visible at 62x and a UHC filter.  The "head and neck" section is easy to view along with the fainter "bill" and a long body extending from head.  Located west of the North America Nebula in a rich field between two mag 7 stars.

 

8" (6/22/81): faint, surrounding scattered group of stars at 50x and UHC filter.  Appears as a bright patch to the west of two bright stars (neck section).

 

Reverend Thomas Espin discovered IC 5070, along with IC 5068, visually on 7 Sep 1899 with a 17 1/4-inch reflector at his Tow Law observatory in England. The discovery was included in a short list of 6 new objects (including the Cocoon Nebula) in AN 3633 and noted as "faint and diffused".  His position corresponds with the "neck" of the Pelican, the brightest part of the nebula, so the identification is certain.

 

Max Wolf photographed the region surrounding the North American Nebula on 1 Jun 1891 (AN 3048) on a 3 hour plate. He gives a general description of the region with no specific positions, though mentions strong nebulosity was recorded around the stars 56 and 57 Cygni, which are involved in the Pelican Nebula.  So, certainly it was captured on his early image.  Espin is credited with the discovery in the IC2, but Wolf should share credit.

Lewis Swift discovered IC 5131 = Sw.

18" (10/29/11): faint, small glow surrounding a mag 12 star about 4' NNW of the main section of NGC 7129.  IC 5133, a slightly fainter glow and central star lies 1' NE.

 

17.5" (10/17/98): IC 5132 and IC 5133 refers to faint nebulosity surrounding a pair of mag 12 stars at 1' separation situated ~5' NNW of NGC 7129 (same complex of reflection nebulae).  It was difficult to verify with certainty as the background sky around six stars arranged in two parallel rows each ~2' in length appears to be weakly glowing.  IC 5132 and 5133 are surrounding the two stars closest to NGC 7129 and the background glow does appear very slightly enhanced around these stars.

 

Isaac Roberts discovered IC 5132 and 5133 on a photograph taken 25 Sep 1895 of NGC 7129. He described "there are three star, each about 13th magnitude, surrounded by very faint nebulosity in the positions following, measured from the centre of the tristellar nucleus of the nebula: (1) 358" north following; (2) 326" north preceding; (3) north preceding.  The stars Nos. 2 and 3 are not referred to in Dr. Dreyer's catalogues, and the measurements given above are approximate.  His offsets identify the two stars given here, although Dreyer's positions are offset to the southwest.  Roberts' first object didn't make it into the IC as Dreyer apparently thought it was identical to NGC 7133.

CGCG 427-040, just 2.7' ENE, appeared extremely to very faint, small, round, 20" diameter, low even surface brightness.  CGCG 427-040 is misidentified as IC 5144 in MCG, PGC and HyperLeda.  UGC 11845 lies 4.6' ESE.  This difficult edge-on (B = 16.1) appeared extremely faint, fairly small, elongated 2:1 NW-SE, ~20"x10", very low surface brightness! A mag 13 star lies 1.3' SE.

 

E.E. Barnard discovered IC 5144, along with IC 5145, on 30 Jul 1888 and described in his notebook, "1 outer radius + 1 thickness [of Ring micrometer] = 7' 17" south and 17 seconds +/- preceding this nebula [IC 5145] is a small faint neb close preceding several small stars." Dreyer was notified privately of both of these discoveries.  Very close to Barnard's offset from IC 5145 is the brightest galaxy of 4 within 3', which matches his description. MCG, PGC, and HyperLeda (as of late 2015) misidentify CGCG 427-040 as IC 5144 (though has an uncertain symbol).  See Harold Corwin's notes for more.

E.E. Barnard discovered IC 5145, along with IC 5144, on 30 Jul 1888 with the 12-inch refractor at Lick Observatory.  It was found after comet-seeking "in the field and s.p. an 8th magnitude star [mag 7.7 HD 208277]."  He notified Dreyer directly, so no discovery announcement was published before the IC was published.  His position is 4.3' too far northwest, but shares the same offset with IC 5144.

Size 12'x12'

 

17.5" (8/8/91): at 82x using an H-Beta filter, the Cocoon Nebula appears fairly bright, very large, about 10' diameter.  Surrounds six stars including two bright mag 9-10 stars embedded near the center and at the south edge.  Has an irregular round shape with a very irregular surface brightness with dark mottling and brighter regions.  The nebula is quite prominent using an H-Beta filter, which gives an excellent contrast gain (higher than OIII). The nebulous glow is superimposed on a scattered star group and is situated at the east end of long dark lane = B168 which extends 1¡ WNW! (excellent in binoculars).  There is a distinctive edge to the Milky Way on the north edge of lane.

 

8" (8/12/83): about 20 stars over a very faint "milky" region, fairly large, just slightly higher contrast than Milky Way background.  A short arc of stars is off the west edge.  A long starless dark lane extends west.  Two bright stars oriented N-S are just east.

 

E.E. Barnard discovered IC 5146 = Cocoon Nebula on a photograph taken 11 Oct 1893 using the 6" Willard lens at Lick Observatory.  Max Wolf also photographed the field on 28 Jul 1894 with the 6-inch camera at Kšnigstuhl.  Wolf announced his discovery with a photograph taken on 10 Jul 1904 and discussed the dark lane (Barnard 168) and nebulosity in detail in his paper "Remarkable nebula in Cygnus" (MNRAS, 64, 838,1904).

 

Mary Clerke, who was in correspondence with Wolf at the time, includes Wolf's 1904 photograph (plate XX) in her second edition (1905) of "The System of the Stars".  She labeled the photograph "The Cocoon Nebula in Cygnus" and writes (p. 352) "The depicted nebula, which had been discovered ten years previously, is about 10' in diameter, of a round shape, and a complex structure.  "It is placed centrally," Dr. Wolf writes, "in a very fine lacuna void of faint stars, which surrounds the luminous cloud like a trench."  Moreover, this negative "halo forms the end of a long channel, running eastward from the western nebulous clouds and their lucanae, to a length of more the two degrees."  The coexistence in the same sidereal district of nebulae and stars could not well be asserted with stronger emphasis than by clearly of a dark fosse for the accommodation of the cocoon-like object in Plate XX."  I tracked down the nickname after a discussion on AMASTRO in August 2015.

 

The Reverend Thomas Espin discovered the nebula visually on 13 Aug 1899 and described object #6 in AN [3633] 152, 141 as a "large, faint glow about 8', well seen each night [2]."  Espin and Wolf is credited with the discovery in the IC.

 

Dave Riddle notes that B168 could apply to both the bright nebula and the associated dark lane. Barnard refers to a "small nebula at the E end of dark lane. This nebula is 10' in diameter with over a dozen stars of different magnitudes in it. There is no central condensation, nor does the nebula condense about any of the stars. There are some dark markings in it. The dark lane is 1.7 degrees long and 9' wide."

V = 11.0;  Size 120"

 

48" (10/23/14): beautiful, large annular planetary at 375x, round, roughly 2' diameter, with a relatively thick annulus and a 30" central dark hole.  Contains a very easy central star, which seems brighter than mag 16.5.  The annulus is mottled and irregular in brightness.  A 60¡ arc along the NW portion of the annulus is slightly brighter and a 90¡ arc from SE to NE is much brighter and a little thicker.  A mag 10.5 star is off the SSW side (1.9' from center), but there are no superimposed stars.

 

18" (8/30/08): viewed from Lake Sonoma at a very low elevation, though in a dark portion of the southern sky.  Beautiful view at 115x using an OIII filter as a 2' annular ring with a relatively thick rim and 30" central hole.  A mag 10.5 star is close off the SSW side (1.8' from the center).

 

18" (7/6/02 - Magellan Observatory, Australia): at 171x and UHC filter, this beautiful planetary appears as a large round ring, nearly 2' diameter, with a bright, thick annulus that is irregularly lit.  The rim is slightly brighter and thicker along the SE side and also appeared slightly enhanced on the NW side.  The central hole appears 25"-30" diameter and is dark except for a central star that was intermittently visible with averted vision at 228x unfiltered, although it is listed with a magnitude of 16.5!  Good contrast enhancement with a UHC filter.  A mag 10.5 is off the SSW side, 1.8' from the center.

 

17.5" (10/30/99): Even at -39¡ declination, this moderately large planetary is a beautiful annular ring at 100x with an OIII filter.  Appears round, ~100" diameter, the annulus has an irregular surface brightness.  The central "hole" is perhaps 25" in diameter and fairly dark.  A mag 10.5 star is close off the SSW edge.

 

17.5" (8/20/88): perfect annular 2' ring visible at 82x using an OIII filter.  A mag 10.5 star is just off the SSW edge 1.8' from the center.  The ring-shape is clearly visible with direct vision.

 

17.5" (7/22/87): beautiful ring at 140x with an OIII filter.  Appears fairly large, fairly bright with a mag 11 star off the south edge.

 

13.1" (8/17/85): fairly faint with OIII at 79x, fairly large.  Appears clearly annular with averted vision.  The central hole is possibly elongated N-S. A mag 11 star is off the south edge.  Similar view on 7/20/85.

 

Walter Gale, an amateur from Sydney, discovered IC 5150 on 4 Jun 1894 with his 8.5-inch reflector from Paddington and it was reported in the B.A.A. Vol VI, No. 5 (p218) in 1895.  He found it just visible in a 6-inch reflector and a 5-inch refractor.  Using his new 10-inch reflector, he noted that it spanned 45"x35" N-S with the central vacancy less than half the diameter and not entirely dark.  He also commented it was remarkable that such a relatively bright object was overlooked by JH.

 

Lewis Swift independently found this planetary on 23 July 1897 on Echo Mountain in southern California and recorded XII-29 as "vF, L, lE, 2 B st point to it, nearest in contact."  Swift's position for XII-29 = IC 5148 was 30 sec of RA too small.  By priority, the primary designation should be IC 5150 (from Gale), although it is generally known as IC 5148 or IC 5148-50.  Baracchi observed it using the Great Melbourne Telescope and described the planetary as almost circular, ~1.5' diameter, not quite dark in the central portion.

24" (8/13/15): first in the NGC 7242 group.  At 375x appeared fairly faint, fairly small, very elongated up to 5:1 WSW-ENE, ~30"x6".  Located 7.4' due west of NGC 7242 in a rich star field with a mag 11.5 star 1.6' ENE.

 

17.5" (7/15/93): first of 7 in the NGC 7242 group.  Very faint, small, elongated 5:2 WSW-ENE.  Located near the intersection of two collinear rays of stars.  A mag 11 star is 1.7' NE at the intersection point.  Located 7.4' W of NGC 7242.

 

17.5" (7/28/92): very faint, small, very elongated 3:1 SW-NE.  A mag 11 star is 1.5' NE.  First in the NGC 7242 group and second brightest in a group with NGC 7240 3.5' ESE, IC 1441 3' E and NGC 7242 7' E.

 

E.E. Barnard discovered IC 5191, along with IC 5192 and IC 5193, on 5 Dec 1888 using the 12-inch refractor at Lick Observatory.  His very accurate discovery sketch (reproduced from his notebook in AN #4136) matches UGC 11963.  He called it the second brightest and largest of 6 in the group.  He computed the position for the brightest member (NGC 7242), though was uncertain if it was NGC 7242 or 7240.  MCG misidentifies IC 5191 as IC 1441.  UGC (11963) and CGCG (513-020) don't identify their catalogue entries as IC 5191.  See Corwin's notes.

18" (7/2/08): picked up easily at 174x as a "soft" mag 11.5 with a pale blue color.  Good contrast gain blinking with an OIII filter.  A brighter mag 10 comparison star lies 1.8' S but blinking with the filter the planetary switches apparent brightness with this star.  At 435x appeared as an 7"x5" blue disc, slightly elongated SSW-NNE.  With direct vision, a slightly brighter quasi-stellar center was visible suggesting the central star was just below the threshold of visibility.

 

18" (12/08/07): picked up at 115x as a soft blue-grey "star".  Good contrast gain using a NPB filter.  Without a filter, a brighter mag 10 star lies to the south though with the filter the planetary matches the star.  At 225x a definite small disc is visible, crisp-edge, round, ~6" diameter.  Seeing too soft for high power.

 

13.1" (10/10/86): at 166x appears fairly bright but just non-stellar.  Good contrast gain with OIII filter.  A bright compact bluish disc is visible at 214x, slightly elongated.  Estimate V = 11.5 and 5" diameter.  Located 1.3¡ due south of mag 4.4 Beta Lac.

13.1" (10/20/84): faint, small, very elongated 3:1 SW-NE, brighter center.  Forms a pair with IC 5270 11' NNE and IC 1459 lies 26' SSW.

 

13.1" (7/20/85): fairly small, elongated SW-NE, brighter center.

 

Lewis Swift discovered IC 5269 = Sw. XI-222 on 10 Sep 1896 and reported "vF; pS; R; np of 2 [with IC 5270]."  His position is 10 seconds of RA west and 6' north of ESO 406-032 = PGC 70110, not unusual for his later IC positions.  Swift confused the orientation as IC 5269 is the south-preceding of the pair, though the discovery dates are a month apart so the positions were recorded on different nights.  MCG reverses the identifications of IC 5269 and IC 5270.

18" (10/25/08): fairly faint, moderately large, elongated 3:1~ E-W, 1.2'x0.4'.  This galaxy sits at the north end of the Grus Chain that extends to NGC 7421 ~1.5 degrees south.

 

13.1" (7/20/85): faint, edge-on ~E-W, even surface brightness.  Otherwise similar in size and brightness to IC 5269 11' SSW.  The IC orientation for the pair is incorrect.  This galaxy is the furthest north in a string of ~10 galaxies stretching south to IC 5273.

 

Lewis Swift discovered IC 5270 = Sw XI-223 on 12 Aug 1896 and recorded "vF; pS; vE; sf of 2 [with IC 5269]."  His position is 14' too far south and IC 5270 is the north-following of 2.  According to Swift's large AN table, he discovered nearby IC 5269 a month later, though the pair would have both been in his 33' field.  He probably added the comment "sf of 2" when preparing the table for publication.  MCG reverses the identifications of IC 5269 and IC 5270, probably because Swift's position for IC 5269 is 10' north of IC 5270 .

 

E.E. Barnard probably made an earlier observation of IC 5270 and IC 5269 on 15 Dec 1889 with the 12-inch refractor at Lick Observatory.  He recorded in his logbook, "pL, vF, extended, a small, faint __ (can't decipher word) 5' +/- S.  A 6m star 22' N and 1' following."  There is nothing at his position (in ink), but his declination is just 3' off from IC 5270 and the galaxy 5' +/- south is probably IC 5269.  The 6th mag star HD 217096 is 22' NNE of IC 5270, though 8' following.  Barnard never published these discoveries or informed Dreyer, so Swift is credited in the IC.

E.E. Barnard discovered IC 5273 = Sw XI-224 on 12 Dec 1889, while searching for Brorsen's Comet (5D/Brorsen) with the 12-inch refractor at Lick Observatory.  He recorded in his logbook, "pB, E, 1' dia, 12th mag."  His rough position (no offsets) is 7' too far south.  Immediately afterwards he logged "fogged all over and the entire heavens blotted out."  Lewis Swift independently discovered this galaxy on 12 Aug 1896 and recorded "vF, cL, lE, 2 wide D st near p."  Swift is credited with the discovery in the IC as Barnard never published his discovery or informed Dreyer.

Andrew Common possibly discovered this galaxy 17 years earlier.  He remarked for NGC 7594 (#27 in his discovery list), "f[ollows] 3 stars in a line 90 degrees pointing to another fainter nebula s(outh)".  The nebula to the south is IC 1478 and the northern "star" is probably IC 5305.

James Dunlop possibly made the first observation.  He described D 546 (discovered on 14 Jul 1826) as an "extremely feeble nebula, ill defined; it appears rather elongated oblique to the equator; it is north following a star of the 7th magnitude, and also north of the small stars."  If this identification is correct (suggested by Glen Cozens), then Dunlop made a typo of 1 degree too far south in his position and 1 min of RA too large.  I'm skeptical, though, as this face-on spiral displays no elongation.

Herbert Howe discovered IC 5349 = Ho. II-15 on 16 Nov 1898 and recorded "vF, vmE 200¡, 20" long."  His position and description is an exact match.  He also added the note "No. 15 has puzzled me somewhat.  The southern end is the brightest portion, and at times it seems as if the object were really a faint double star, one or both components of which are nebulous."  He was right about this object being double!
