Historical Identification: Per Dreyer, IC 5050 (= Javelle #1403, 1860 RA 20 37 51, NPD 96 08.1) is "faint, considerably small, diffuse, very small elongated nucleus". The position precesses to RA 20 45 16.0, Dec -05 37 48, only 0.5 arcmin southeast of the galaxy listed above, the description fits and there is nothing else nearby, so the identification is certain.
Physical Information: Apparent size 1.45 by 0.9 arcmin.

Historical Identification: Per Dreyer, IC 5051 (= DeLisle Stewart #690, 1860 RA 20 37 55, NPD 162 18) is "extremely faint, very small". The position precesses to RA 20 52 19.2, Dec -71 47 08, only a third of an arcmin northwest of the galaxy listed above and there is nothing else nearby that isn't accounted for by another of Stewart's discoveries, so the identification is certain.
Physical Information: Apparent size 0.65 by 0.4 arcmin.

Historical Identification: Per Dreyer, IC 5052 (= DeLisle Stewart #692, 1860 RA 20 38 43, NPD 159 44) is "faint, large, extremely extended 140°, 4 arcmin long". The position precesses to RA 20 52 08.4, Dec -69 13 05, on the southwestern rim of the galaxy listed above, the description fits and there is nothing else nearby, so the identification is certain.
Physical Information: Apparent size 6.2 by 1.2 arcmin.

Historical Identification: Per Dreyer, IC 5053 (= DeLisle Stewart #694, 1860 RA 20 39 25, NPD 161 40) is "considerably faint, very small, brighter middle, 11th magnitude star 2 arcmin north". The position precesses to RA 20 53 31.1, Dec -71 08 56, on the southwestern extension of the galaxy listed above, there is nothing else nearby and the star to its north makes the identification certain.
Physical Information: Apparent size 2.2 by 0.6 arcmin.

Historical Identification: Per Dreyer, IC 5054 (= DeLisle Stewart #695, 1860 RA 20 39 32, NPD 161 33) is "considerably faint, very small, between 2 faint stars". The position precesses to RA 20 53 35.2, Dec -71 01 55, only about 0.9 arcmin southwest of the galaxy listed above, there is nothing else nearby, and the stars on either side of the galaxy make the identification certain.
Physical Information: Apparent size 2.1 by 0.45 arcmin.

Historical Identification: Per Dreyer, IC 5055 (= DeLisle Stewart #693, 1860 RA 20 39 42, NPD 158 58) is "very faint, brighter middle, suspected". The position precesses to RA 20 52 51.5, Dec -68 26 57, only half an arcmin west southwest of the galaxy listed above and there is nothing else nearby, so the identification is certain.
Physical Information: Apparent size 0.6 by 0.35 arcmin.

Historical Identification: Per Dreyer, IC 5056 (= DeLisle Stewart #691, 1860 RA 20 39 53, NPD 129 42) is "faint, considerably large, extremely extended 150°". The position precesses to RA 20 48 59.3, Dec -39 11 15 (whence the position above), but there is nothing there. Per Corwin, there are no "spindle" galaxies within several degrees of the position, and Stewart found nothing else on the short-exposure (one-hour) Bruce plate involved, so this is probably a plate defect, and therefore a nonexistent object. However, various galaxies have been suggested as candidates over the years, so they are discussed in the following entries as a warning against such misidentifications.

Historical Identification: Although PGC 65452 lies only a few arcmin from Stewart's position for IC 5056, the offset would require a very unlikely combination of errors, and the galaxy does not fit his description, so it is almost certainly not IC 5056 (which as noted in its entry, was probably a plate defect). However, it is listed as IC 5056 in some places (such as LEDA), so it is listed here as a warning about the misidentification.
Physical Information: Apparent size 0.9 by 0.45 arcmin (including its faint southern extension).

Historical Identification: Despite requiring a 20 arcmin error in Stewart's declination, Corwin once suggested that PGC 131465 might be IC 5056, but he has retracted his suggestion because the part of the galaxy bright enough to be seen on Stewart's one-hour Bruce plate is not significantly extended, and therefore does not match the description. However, once such suggestions are made they have a way of creeping back into circulation, so this entry serves as a warning about any future misidentification.
Physical Information: Apparent size 1.05 by 0.5 arcmin.

Historical Identification: Per Dreyer, IC 5057 (= Bigourdan #436, 1860 RA 20 40 04, NPD 90 12) is "extremely faint, nebulous star or extremely small nebula". The position precesses to RA 20 47 14.2, Dec +00 18 38, within the NGC 6962 group of galaxies, but which object in that group is Bigourdan's #436 is not obvious. However, it turns out that the problem is simply the round-off error in Dreyer's positions. As noted by Corwin, Bigourdan's original position (1900 RA 20 42 07.4, Dec -00 02 37) precesses to RA 20 47 14.6, Dec -00 19 23, just east of the star listed above, and Bigourdan's mention of the brighter star 1.5 arcmin south southwest makes the identification certain.

Historical Identification: Per Dreyer, IC 5058 (= Bigourdan #438, 1860 RA 20 40 12, NPD 90 02) is "extremely faint, distinct from (NGC) 6963". The position precesses to RA 20 47 21.8, Dec +00 28 39, only half an arcmin southeast of PGC 65376, and there is nothing else nearby, so the identification with that galaxy is certain. However, several of the NGC objects in the region have a long history of misidentifications, including this one (for instance, LEDA misidentifies NGC 6965 as NGC 6963, and as a result, so does Wikisky).
Physical Information: Given the duplicate entry, see NGC 6965 for anything else.

Historical Identification: Per Dreyer, IC 5059 (= Frost #1213, 1860 RA 20 40 22, NPD 148 12) is "very faint, small, round, diffuse". The position precesses to RA 20 51 16.2, Dec -57 41 02, just off the northeastern rim of the galaxy listed above, the description fits and there is nothing else nearby, so the identification is certain.
Physical Information: Apparent size 1.0 by 0.7 arcmin.

Historical Identification: Per Dreyer, IC 5060 (= DeLisle Stewart #696, 1860 RA 20 40 22, NPD 162 09) is "extremely faint, extremely small, between 2 faint stars". The position precesses to RA 20 54 38.3, Dec -71 37 46, only about 0.7 arcmin northwest of the galaxy listed above, the description fits and there is nothing else nearby, so the identification is certain.
Physical Information: Apparent size 0.9 by 0.2 arcmin.

Historical Identification: Per Dreyer, IC 5061 (= Bigourdan #439, 1860 RA 20 40 28, NPD 90 11) is "extremely faint, very small cluster, perhaps nebulous" (Bigourdan's paper says "cluster of 3 or 4 stars"). The position precesses to RA 20 47 38.1, Dec +00 19 42, just southeast of the group listed above. Taking into account a 1.3 second of time error in the position of Bigourdan's comparison star, his position is only a fraction of a second due east of the group, and given his description of the object, the identification is certain.

Historical Identification: Per Dreyer, IC 5062 (= Bigourdan #336, 1860 RA 20 40 38, NPD 98 53) is a "13.5 magnitude star with extremely faint star and nebula, 13th magnitude star 1 arcmin west". The position precesses to RA 20 48 09.7, Dec -08 22 15, but there is nothing near there save for NGC 6968 (which does not match the description and was separately observed by Bigourdan on the same night he recorded his #336), and an otherwise stellar field. However, there is a double star just north of Dreyer's position that would fit the description if Bigourdan was unable to see it as double, and (per Corwin) using Bigourdan's measurements instead of Dreyer's rounded-off position exactly matches the position of the pair, so the identification of IC 5062 shown above is certain. (Note: Some references, ignoring the reasons noted above that rule out NGC 6968 as IC 5062, mistakenly equate the two; hence the warning in the title for this entry.)

Historical Identification: Per Dreyer, IC 5063 (= Frost #1214, 1860 RA 20 41 05, NPD 147 35) has a "brighter middle, magnitude 13". The position precesses to RA 20 51 53.4, Dec -57 03 56, on the western rim of the galaxy listed above and there is nothing else nearby, so the identification is certain.
Physical Information: Apparent size of about 2.75 by 1.85 arcmin (from the images below). Per the HST press release, about 160 million light-years away and about 54 thousand light-years across. A member of a class of galaxies referred to as luminous infrared galaxies because most of their radiation is emitted in the infrared (the dark dust lanes seen in the images below are partly responsible for that). Judy Schmidt's image of the galaxy revealed a complex pattern of light 'crepuscular' rays and dark shadows, which led to the study discussed in the HST press release. It is believed that as material falls into a black hole in the center of the galaxy (creating an incredibly bright central region, making this a Seyfert (Sy 2) galaxy), a torus of material trying to fall into the black hole but temporarily held back by other material in its way is allowing light to escape in some directions and blocking it in other directions (whence the bright rays and dark shadows aligned with the axis of the galaxy). The brightness of the core also makes dusty regions in the plane of the galaxy stand out in sharp contrast, which we perceive as dark lanes. This makes the galaxy both "peculiar" and right on the borderline between a lenticular galaxy and a spiral, as indicated by the type shown in the description line.

Historical Identification: Per Dreyer, IC 5064 (= Frost #1215, 1860 RA 20 41 41, NPD 147 45) has a "brighter middle, magnitude 14". The position precesses to RA 20 52 30.3, Dec -57 13 50, about 1 arcmin west of the galaxy listed above and there is nothing else nearby, so the identification is certain.
Physical Information: Apparent size 1.25 by 0.7 arcmin.

Historical Identification: Per Dreyer, IC 5065 (= Swift list XII (#24), 1860 RA 20 41 44, NPD 120 20.5) is "very faint, pretty small, round". The position precesses to RA 20 50 15.5, Dec -29 49 30, but there is nothing there. However, the galaxy listed above is at nearly the same declination, and although it is a minute and a half of time to the east of Swift's position, that sort of error is typical of his later observations, and there is nothing else in the region that Swift could have seen. That alone might not be a convincing argument, but fortunately Swift noted (though Dreyer did not) the presence of an 8th magnitude star on the northern margin of his field of view, and as a result the magnitude 7 star north northwest of the galaxy makes the identification certain.
Physical Information: Apparent size 1.0 by 0.75 arcmin for the main part of the galaxy, 1.6 by 1.25 arcmin including fainter extensions.

Historical Identification: Per Dreyer, IC 5066 (= DeLisle Stewart #697, 1860 RA 20 42 10, NPD 163 41) is "very faint, very small, brighter middle". The position precesses to RA 20 57 04.4, Dec -73 09 27, less than 0.7 arcmin south of the galaxy listed above and there is nothing else nearby, so the identification is certain.
Physical Information: Based on a recessional velocity of 12325 km/sec, a straightforward calculation indicates that IC 5066 is about 575 million light years away. However, for objects at such distances we should take into account the expansion of the Universe during the time it took their light to reach us. Doing that shows that the galaxy was about 545 million light years away at the time the light by which we see it was emitted, about 560 million years ago (the difference between the two numbers being due to the expansion of the intervening space during the light-travel time). Given that and its apparent size of 0.65 by 0.65 arcmin, the galaxy is about 105 thousand light years across.

Historical Identification: Per Dreyer, IC 5067 (= Espin (#3), 1860 RA 20 42 56, NPD 46 09) is "faint". The position precesses to RA 20 47 50.2, Dec +44 21 54 (whence the "lost" position above), in an empty area to the west of the Pelican Nebula, so the position gives no indication of what Espin observed, and it might be best to consider IC 5067 as lost. However, the region is filled with emission nebulae, and odds are that what Espin meant to record was one of them. For reasons related to the relative brightnesses recorded by Espin for his #3, #4 and #5, Corwin proposes that the best candidate for IC 5067 is the elongated nebula to the northwest of IC 5068. Whether that is correct or not seems impossible to prove, especially since it lies more than a degree to the southwest of Espin's position, whereas his other observations were reasonably accurate; but since it is a commonly quoted identification, it is listed above as a possibility and is shown in the second and third images below.
Discovery Notes: Max Wolf's paper (A. N. 3048) of June 10, 1891 describes the region in Cygnus near the North American Nebula as photographed on a 3 hour plate taken on June 1 of that year. The description of the region is very general and includes no actual positions, so Dreyer may have ignored the paper because he was not aware of it, or because it included nothing that could help him identify any particular object. Certainly, in the case of IC 5067 there is nothing in Wolf's paper that would help to identify what Espin might have seen; so although Wolf is sometimes listed as the discoverer of IC 5067, it is more appropriate to say that he happened to take a photograph of the region, but failed to provide a description deserving of any credit for this particular entry.
Physical Information: If lost, there is nothing to say. If as identified by Corwin, the apparent size is about 45 by 17 arcmin.

Historical Identification: Per Dreyer, IC 5068 (= Espin (#4), 1860 RA 20 44 52, NPD 47 59) is "very faint". The position precesses to RA 20 49 55.6, Dec +42 32 12, on a patch of nebulosity that is a reasonable fit to the description, and although the position is a few arcmin west northwest of the center of the nebula as defined above (per Corwin's database), the identification is considered certain.
Physical Information: Apparent size about 35 by 30 arcmin.

Historical Identification: Per Dreyer, IC 5069 (= DeLisle Stewart #698, 1860 RA 20 45 47, NPD 162 20) is "extremely faint, small, round". The position precesses to RA 20 59 58.6, Dec -71 47 58, about 1.1 arcmin northwest of the galaxy listed above and there is nothing else nearby, so lthe identification is certain.
Physical Information: Apparent size 1.25 by 1.1 arcmin.

Historical Identification: Per Dreyer, IC 5070 (= Espin (#5), 1860 RA 20 46 00, NPD 46 09) is "faint, diffuse". The position precesses to RA 20 50 55.8, Dec +44 22 22, within the brightest part of the emission nebula listed above (near the "nape of the neck" of the "Pelican"), so the identification is certain. (Note: the position listed above is taken from Corwin's database.)
Discovery Notes: Max Wolf took the first photograph of the region near the North American Nebula on December 12, 1890. In addition, in a paper (A. N. 3048) of June 10, 1891 he described the region near that nebula as photographed on a 3 hour plate taken on June 1 of that year. His description of the region is very general and gives no actual positions, so even if Dreyer was aware of the paper it would have been of no use in trying to determine the nature or positions of objects to be placed in the IC2. There is no doubt that Wolf's photographs recorded the Pelican, and his description of the region, though vague, almost certainly includes that nebula; so he probably deserves some credit for the discovery, and is often given sole credit in modern discussions. However, Espin's accurate position for the nebula was far more useful to Dreyer, so in any discussion of the NGC/IC catalogs Espin must be given credit as discoverer or co-discoverer of IC 5070.
Physical Information: The Pelican Nebula is part of a more than a hundred light year wide region of ionized and neutral hydrogen which includes its more famous companion, the North America Nebula (NGC 7000). The apparent separation and shapes of the nebulae are due to clouds of obscuring dust lying between us and them. What star or stars are responsible for heating the gas was long unknown. Recently the 2MASS infrared telescope, concentrating on the area obscured by dust, has shown that there is a very massive O-type star in the general area of the nebulae that is the most likely source of the ultraviolet radiation stimulating their visible-light emissions. Estimates of the distance of the North American and Pelican nebulae vary considerably, ranging from as little as 1500 light years to as much as 2200 light years. Given that, the 84 by 64 arcmin apparent size of IC 5070 corresponds to perhaps 45 light years.

Historical Identification: Per Dreyer, IC 5071 (= DeLisle Stewart #699, 1860 RA 20 46 47, NPD 163 11) is "considerably bright, small, extremely extended 20°, stellar nucleus". The position precesses to RA 21 01 18.8, Dec -72 38 47, almost dead center on the galaxy listed above, the description fits and there is nothing else nearby so the identification is certain.
Physical Information: Apparent size 4.0 by 0.75 arcmin.

Historical Identification: Per Dreyer, IC 5072 (= DeLisle Stewart #700, 1860 RA 20 47 20, NPD 163 31) is "extremely faint, extremely small, round". The position precesses to RA 21 01 59.9, Dec -72 58 42, only 0.6 arcmin north northeast of the galaxy listed above and there is nothing else nearby, so the identification is certain.
Physical Information: Apparent size 0.7 by 0.3 arcmin.

Historical Identification: Per Dreyer, IC 5073 (= DeLisle Stewart #701, 1860 RA 20 48 54, NPD 163 14) is "extremely faint, small, round". The position precesses to RA 21 03 23.2, Dec -72 41 29, on the southeastern rim of the galaxy listed above and there is nothing else nearby, so the identification is certain.
Physical Information: Apparent size 1.2 by 1.05 arcmin.

Historical Identification: Per Dreyer, IC 5074 (= Frost #1216, 1860 RA 20 49 14, NPD 153 40) is "round, planetary, magnitude 14". The position precesses to RA 21 00 54.1, Dec -63 07 38, about 1.6 arcmin north northwest of the galaxy listed above, but the description fits and there is nothing else nearby so the identification is certain.
Physical Information: Apparent size 0.8 by 0.6 arcmin.

Historical Identification: Per Dreyer, IC 5075 (= DeLisle Stewart #702, 1860 RA 20 50 25, NPD 162 24) is "very faint, small, considerably bright middle". The position precesses to RA 21 04 30.1, Dec -71 51 17, just under an arcmin northwest of the galaxy listed above and there is nothing else nearby, so the identification is certain.
Physical Information: Apparent size 0.85 by 0.4 arcmin.

Historical Identification: Per Dreyer, IC 5076 (= Roberts, 1860 RA 20 51 11, NPD 43 07.0) is "very faint, very large, a little extended north-south, stars involved". The position precesses to RA 20 55 54.7, Dec +47 25 08, just east of the nebula listed above, and although the right ascension is off by 20 seconds of time, the error is small in comparison with the size of the nebula, the description fits perfectly and there is nothing comparable nearby, so the identification is certain.
Physical Information: Apparent size 11 by 8 arcmin.

Historical Identification: Per Dreyer, IC 5077 (= DeLisle Stewart #704, 1860 RA 20 54 12, NPD 164 12) is "extremely faint, extremely small, 10th magnitude star 2 arcmin northwest". The position precesses to RA 21 08 58.2, Dec -73 38 41, only 0.4 arcmin southeast of the galaxy listed above, there is nothing else nearby and the star to its northwest makes the identification certain.
Physical Information: Apparent size 0.6 by 0.45 arcmin.

Historical Identification: Per Dreyer, IC 5078 (= DeLisle Stewart #703, 1860 RA 20 54 45, NPD 107 22) is "extremely extended, near 2nd star of 3; suspected". The position precesses to RA 21 02 36.2, Dec -16 49 07, on the eastern rim of the galaxy listed above, the description fits and there is nothing else nearby, so the identification is certain.
Physical Information: Apparent size 4.1 by 0.9 arcmin.

Historical Identification: Per Dreyer, IC 5079 (= Innes (#11), 1860 RA 20 55, NPD 146 48) is "faint, small, extended, perhaps a very small cluster or ring nebula" (Inne's paper adds that it is elongated by 15 arcsec, and has a brightness equivalent to a 9.7 magnitude star). The position precesses to RA 21 05 30.2, Dec -56 14 53 (whence the position above), but there is nothing there. Corwin has suggested that IC 5079 might be the magnitude 11.5 star northeast of Innes' position, but since that is two magnitudes fainter than the description, feels that such an identification would be a stretch. However, on the image below it appears that Corwin's "star" is actually a double, and on the DSS plate the pair is about 15 arcsec across, which matches Innes' description. So although IC 5079 appears to be lost or nonexistent, there is a possibility that it is Corwin's star.

Historical Identification: Per Dreyer, IC 5080 (= Javelle #1404, 1860 RA 20 56 09, NPD 71 19.5) is "faint, very small, round, stellar nucleus". The position precesses to RA 21 02 33.8, Dec +19 13 29, only 0.7 arcmin north northeast of the galaxy listed above and there is nothing else nearby, so the identification is certain.
Physical Information: Apparent size 0.65 by 0.55 arcmin.

Historical Identification: Per Dreyer, IC 5081 (= Javelle #1405, 1860 RA 20 56 37, NPD 71 20.9) is "very faint, very small, round, stellar nucleus". The position precesses to RA 21 03 01.9, Dec +19 12 09, about 0.8 arcmin north northeast of the galaxy listed above and there is nothing else nearby, so the identification is certain.
Physical Information: Apparent size 0.6 by 0.25 arcmin.

Historical Identification: Per Dreyer, IC 5082 (= Bigourdan #440, 1860 RA 20 57 00, NPD 102 54) is "extremely faint, small". The position precesses to RA 21 04 39.8, Dec -12 20 48, on the southern rim of the galaxy listed above and there is nothing else nearby, so the identification is certain. However, the galaxy happens to be the same as NGC 7010, so this is a duplicate listing. Per Corwin, the cause of the duplication was that Herschel's position was 10 arcmin too far south, and although Howe brought attention to Herschel's error, when Dreyer listed the corrected position for NGC 7010 (1860 RA 20 56 59, NPD 102 53.5) at the end of the IC2 he failed to notice that it was essentially identical to Bigourdan's position.
Physical Information: Given the duplicate entry, see NGC 7010 for anything else.

Historical Identification: Per Dreyer, IC 5083 (= Swift list XI (#203), Howe, 1860 RA 20 57 08, NPD 78 47.4) is "most extremely faint, very small, very difficult; 8th magnitude star 13 seconds of time to east". The position precesses to RA 21 03 51.5, Dec +11 45 45, right on the galaxy listed above, there is nothing else nearby, and the star to the east makes the identification certain.
Physical Information: Apparent size 0.85 by 0.6 arcmin. A foreground star superimposed on the nucleus partially obscures it.

Historical Identification: Per Dreyer, IC 5084 (= DeLisle Stewart #705, 1860 RA 20 57 34, NPD 153 51) is "faint, pretty small, extremely extended 155°, considerably brighter middle". The position precesses to RA 21 09 06.6, Dec -63 17 27, about 0.9 arcmin west of the galaxy listed above, the description fits and there is nothing else nearby, so the identification is certain.
Physical Information: Apparent size 1.65 by 0.6 arcmin.

Historical Identification: Per Dreyer, IC 5085 (= DeLisle Stewart #706, 1860 RA 20 58 34, NPD 164 40) is "very faint, very small, round". The position precesses to RA 21 13 25.1, Dec -74 06 04, on the northwestern rim of the galaxy listed above and there is nothing else nearby, so the identification is certain.
Physical Information: Apparent size 0.6 by 0.45 arcmin.

Historical Identification: Per Dreyer, IC 5086 (= Swift list XI (#204), 1860 RA 20 59 06, NPD 120 36.0) is "most extremely faint, pretty small, round, faint star to east". The position precesses to RA 21 07 32.5, Dec -30 02 27, but as in the case of many of Swift's later observations, there is nothing there. The only "nearby" candidate is a minute of time to the east and more than a quarter degree to the north, a combination of positional errors that makes its identification as IC 5086 less than certain; but (as noted by Corwin) the description perfectly fits the candidate, so the identification is as certain as possible under the circumstances.
Physical Information: Apparent size 2.0 by 1.6 arcmin.

Historical Identification: Per Dreyer, IC 5087 (= DeLisle Stewart #707, 1860 RA 20 59 44, NPD 164 21) is "very faint, very small, 11th magnitude star 3 arcmin northwest". The position precesses to RA 21 14 23.2, Dec -73 46 55, only half an arcmin south southeast of the galaxy listed above, there is nothing else nearby and the star to the northwest makes the identification certain.
Physical Information: Based on a recessional velocity of 16140 km/sec, a straightforward calculation indicates that IC 5087 is about 750 million light years away. However, for objects at such distances we should take into account the expansion of the Universe during the time it took their light to reach us. Doing that shows that the galaxy was about 705 million light years away at the time the light by which we see it was emitted, about 725 million years ago (the difference between the two numbers being due to the expansion of the intervening space during the light-travel time). Given that and its apparent size of 0.6 by 0.5 arcmin, the central condensation of the galaxy is about 125 thousand light years across, while its 1.6 arcmin wide extended arms span 330 thousand light years.

Historical Identification: Per Dreyer, IC 5088 (= Howe list I (#16), 1860 RA 21 01 21, NPD 113 26.6) is "extremely faint, very small, difficult". The position precesses to RA 21 09 26.6, Dec -22 52 45, right on the galaxy listed above and there is nothing else nearby, so the identification is certain.
Physical Information: Apparent size 1.5 by 1.45 arcmin.

Historical Identification: Per Dreyer, IC 5089 (= Barnard, 1860 RA 21 03 38, NPD 94 25.1) is "extremely faint, very small, brighter middle, faint star 30 arcsec southwest". The position precesses to RA 21 10 57.6, Dec -03 50 59, about 1.1 arcmin northeast of the galaxy listed above and there is nothing else nearby. The only problem is that Barnard reversed the direction of the nearby faint star; but as noted by Corwin this is a common error, and the mere presence of the star is enough to make the identification certain.
Physical Information: Apparent size 0.55 by 0.2 arcmin.

Historical Identification: Per Dreyer, IC 5090 (= H. C. Wilson, 1860 RA 21 04 16, NPD 92 36.2) is "very faint, small, round, suddenly brighter middle". The position precesses to RA 21 11 31.5, Dec -02 02 00, on the eastern rim of the galaxy listed above and there is no other suitable candidate nearby, so the identification is certain.
Physical Information: Apparent size 1.0 by 0.5 arcmin.

Historical Identification: Per Dreyer, IC 5091 (= DeLisle Stewart #708, 1860 RA 21 04 28, NPD 161 14) is "extremely faint, very small, round". The position precesses to RA 21 17 42.4, Dec -70 39 22, less than half an arcmin north east northeast of the galaxy listed above, the description is reasonable and there is nothing else nearby, so the identification appears certain.
Physical Information: Apparent size 0.5 by 0.45 arcmin.

Historical Identification: Per Dreyer, IC 5092 (= Frost #1217, 1860 RA 21 04 32, NPD 155 03) is "pretty large, extended, much brighter middle". The position precesses to RA 21 16 10.0, Dec -64 28 28, right on the galaxy listed above, the description fits and there is nothing else nearby, so the identification is certain.
Physical Information: Apparent size 2.7 by 2.4 arcmin.

Historical Identification: Per Dreyer, IC 5093 (= DeLisle Stewart #710, 1860 RA 21 05 34, NPD 161 13) is "most extremely faint, very small, round, suspected". The position precesses to RA 21 18 46.1, Dec -70 38 13, only 0.9 arcmin south of the galaxy listed above and there is nothing else nearby, so the identification is certain.
Physical Information: Apparent size 0.6 by 0.3 arcmin.

Historical Identification: Per Dreyer, IC 5094 (= DeLisle Stewart #709, 1860 RA 21 05 56, NPD 157 01) is "very faint, very small, round, star 0.5 arcmin northwest". The position precesses to RA 21 17 57.4, Dec -66 26 15, only an arcmin southeast of the nucleus of the galaxy listed above, there is nothing else nearby, and the star half an arcmin northwest of the nucleus (on the galaxy's northwestern rim in modern images) makes the identification certain.
Physical Information: Apparent size 1.6 by 1.0 arcmin.

Historical Identification: Per Dreyer, IC 5095 (= Frost #1218, 1860 RA 21 06 29, NPD 150 31) is "pretty large, extended". The position precesses to RA 21 17 18.3, Dec -59 56 15, less than 0.8 arcmin northwest of the galaxy listed above, the description more or less fits and there is nothing else nearby, so the identification is considered certain.
Physical Information: Apparent size 0.8 by 0.35 arcmin. The bright spots east and west of the center of IC 5095 are probably foreground stars, and it is possible that the middle one is also a star; but in the hope that it is actually the nucleus of the galaxy, its position is usually used as that of the IC object, so its coordinates are the ones listed above.

Historical Identification: Per Dreyer, IC 5096 (= DeLisle Stewart #711, 1860 RA 21 06 54, NPD 154 20) is "faint, pretty large, extremely extended 145°, stellar nucleus". The position precesses to RA 21 18 20.7, Dec -63 45 09, right on the galaxy listed above, the description fits and there is nothing else nearby, so the identification is certain.
Physical Information: Apparent size about 3.6 by 0.5 arcmin.

Historical Identification: Per Dreyer, IC 5097 (= Bigourdan #441, 1860 RA 21 07 57, NPD 86 07) is "extremely faint, stellar, 3 arcmin southeast of (NGC) 7045". The position precesses to RA 21 14 58.1, Dec +04 27 41, which falls in a completely stellar field, implying that what Bigourdan recorded was either a single star or a small grouping of stars. Bigourdan's paper states that his #441 is "almost certainly nebulous", and the position he gives does lie 3.0 arcmin from NGC 7045 (though at a position angle of 140°), which is just a pair of stars itself. Since Dreyer rounded off Bigourdan's NPD, his position is not quite the same as that recorded by Bigourdan, which precesses to RA 21 14 58.0, Dec +04 28 09, about 0.2 arcmin west of a star chosen by Thomson as IC 5097, but (per Corwin) Bigourdan's measurements for this and the following entry (IC 5098) were not made to the same accuracy as most of his observations, so the exact position is not as good a guide to what Bigourdan saw as might usually be expected. Based on that and the statement that the object was almost certainly nebulous, Corwin suggests that what Bigourdan observed was the group of three stars directly north of his recorded position; and I agree that this asterism is a better fit for Bigourdan's description, so this entry treats Corwin's suggestion as correct, and that group is the one listed above. However, given the uncertainty inherent in such situations, the identification cannot be considered certain (hence my use of the word "probably" in the identification line), so I have also indicated Thomson's candidate by circling it in the closeup image below.

Historical Identification: Per Dreyer, IC 5098 (= Bigourdan #442, 1860 RA 21 07 59, NPD 86 05) is "extremely faint, 2.5 arcmin east southeast of (NGC) 7045" (Bigourdan described the object as a single star of magnitude 13.4 or 13.5, with a position angle of 100° relative to NGC 7045). The position precesses to RA 21 15 00.1, Dec +04 29 41, but as in the case of IC 5097 (which see for an image of the field) there is nothing there save for a completely stellar field, so IC 5098 must also be a stellar grouping, and even though the position angles are only estimates, they make it clear that IC 5098 must be somewhere to the north of IC 5097. Based on Bigourdan's description, Thomson suggested the star listed above as the most likely candidate for IC 5098, but Corwin chose the double star to its east. I prefer Corwin's suggestion for IC 5097 (as discussed in its entry), but for IC 5098 I prefer Thomson's. The reason is that although Bigourdan's distances are only estimates, the fact that he placed IC 5098 closer to NGC 7045 than IC 5097 suggests that it should be north or northwest of IC 5097, not northeast; but the caveats mentioned for IC 5097 also apply to IC 5098, so I have shown both the choices I adopted and the ones I rejected in the image posted above.

Historical Identification: Per Dreyer, IC 5099 (= DeLisle Stewart #712, 1860 RA 21 08 40, NPD 161 35) is "very faint, small, a little extended 10°". The position precesses to RA 21 21 54.0, Dec -70 59 47, about 0.9 arcmin south southeast of the galaxy listed above, the description fits and there is nothing else nearby, so the identification is certain.
Physical Information: Apparent size 0.8 by 0.3 arcmin.
