IC 4800 (= PGC 62637)
Discovered (Aug 13, 1901) by
DeLisle Stewart
A magnitude 12.2 spiral galaxy (type (R')SB(s)a?) in Pavo (RA 18 58 43.4, Dec -63 08 20)
Historical Identification: Per Dreyer, IC 4800 (= DeLisle Stewart #538, 1860 RA 18 45 31, NPD 153 19) is "very faint, small, stellar nucleus, oval ring, 2 wisps". The position precesses to RA 18 58 42.6, Dec -63 08 27, right on the galaxy listed above, the description fits, and there is nothing else nearby, so the identification is certain.
Physical Information: Based on a recessional velocity of 4500 km/sec, IC 4800 is about 210 million light years away. Given that and its apparent size of 1.8 by 1.1 arcmin, it is about 110 thousand light years across.

IC 4801 (= PGC 62655)
Discovered (Aug 13, 1901) by
DeLisle Stewart
A magnitude 12.5 lenticular galaxy (type SAB0(r)a?) in Pavo (RA 18 59 38.3, Dec -64 40 30)
Historical Identification: Per Dreyer, IC 4801 (= DeLisle Stewart #540, 1860 RA 18 45 54, NPD 154 51) is "considerably faint, small, round, brighter middle". The position precesses to RA 18 59 30.8, Dec -64 40 20, on the northwestern rim of the galaxy listed above, and there is nothing else nearby, so the identification is certain.
Physical Information: Apparent size 2.0 by 1.2 arcmin.

IC 4802 (= part of
NGC 6717 = GCL 105)
Recorded (Jun 30, 1884) by Guillaume Bigourdan
A group of stars in Sagittarius (RA 18 55 07.2, Dec -22 41 51)
Historical Identification: Per Dreyer, IC 4802 (= Bigourdan #434, 1860 RA 18 46 40, NPD 112 52) is a "nebulous 13th magnitude star, 15 arcsec northeast of III 143" ((WH) III 143 being NGC 6717). The position precesses to RA 18 55 07.0, Dec -22 41 42, right on the knot of stars a quarter arcmin northeast of the center of globular cluster NGC 6717, so the identification is certain, as shown in the images below. Per Corwin, IC 4802 is sometimes identified as NGC 6717, or as a faint star 2 arcmin northeast of NGC 6717; but since Bigourdan used the main body of the cluster as his reference, IC 4802 can't be the whole cluster, and both the appearance and position of the individual star fail to match the description, so that identification must also be wrong.

IC 4803 (= PGC 62677)
Discovered (Aug 13, 1901) by
DeLisle Stewart
A magnitude 14.8 spiral galaxy (type S pec?) in Pavo (RA 19 00 39.9, Dec -62 03 54)
Historical Identification: Per Dreyer, IC 4803 (= DeLisle Stewart #541, 1860 RA 18 47 42, NPD 152 15) is "most extremely faint, extremely small, round". The position precesses to RA 19 00 36.7, Dec -62 04 03, less than 0.4 arcmin southwest of the galaxy listed above, so the identification is essentially certain. However, per Corwin, it is not unusual for IC 4803 to be misidentified as including the pair of galaxies to the east of PGC 62677, so the others (PGC 62681 and 62684) are also discussed immediately below.
Physical Information: Apparent size 0.7 by 0.35 arcmin.

A magnitude 15.2 spiral galaxy (type SBc? pec) in Pavo (RA 19 00 55.1, Dec -62 03 44)
Historical Identification: See IC 4803 about the misidentification, and for a wide-field view.
Physical Information: Recessional velocity unknown, but apparently interacting with PGC 62681 (which see for an image of the pair), so presumably at the same distance. Apparent size 0.7 by 0.35 arcmin.

IC 4804 (= PGC 62685)
Discovered (Aug 13, 1901) by
DeLisle Stewart
A magnitude 14.1 spiral galaxy (type SA(s)c?) in Pavo (RA 19 01 07.3, Dec -61 49 59)
Historical Identification: Per Dreyer, IC 4804 (= DeLisle Stewart #542, 1860 RA 18 48 13, NPD 152 00) is "most extremely faint, extremely small, considerably extended". The position precesses to RA 19 01 03.9, Dec -61 48 57, just over an arcmin north northwest of the galaxy listed above, the bright spot northwest of the nucleus probably makes the description fit, and there is nothing else nearby, so the identification appears to be certain.
Physical Information: Apparent size 1.45 by 1.05 arcmin.

IC 4805 (= PGC 62693)
Discovered (Aug 13, 1901) by
DeLisle Stewart
A magnitude 13.6 spiral galaxy (type Sa?) in Pavo (RA 19 02 01.3, Dec -63 02 52)
Historical Identification: Per Dreyer, IC 4805 (= DeLisle Stewart #543, 1860 RA 18 48 50, NPD 153 14) is "extremely faint, very small, extremely extended 25, brighter middle". The position precesses to RA 19 01 59.0, Dec -63 02 48, just west of the galaxy listed above, the description fits and there is nothing else nearby, so the identification is certain.
Physical Information: Apparent size 1.45 by 0.4 arcmin.

A magnitude 12.2 spiral galaxy (type (R')SA(s)b?) in Pavo (RA 19 01 30.6, Dec -57 31 55)
Historical Identification: Per Dreyer, IC 4806 (= DeLisle Stewart #544, 1860 RA 18 49 29, NPD 147 43) is "most extremely faint, extremely small, extremely extended 10, 2 stars very near, suspected". The position precesses to RA 19 01 25.8, Dec -57 31 47, less than 0.7 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 2.4 by 0.6 arcmin.

Discovered (Sep 16, 1901) by
DeLisle Stewart
A magnitude 13.4 spiral galaxy (type SB(s)c?) in Pavo (RA 19 02 17.5, Dec -56 55 51)
Historical Identification: Per Dreyer, IC 4807 (= DeLisle Stewart #546, 1860 RA 18 50 25, NPD 147 07) is "very faint, very small, a little extended, planetary?, suspected". The position precesses to RA 19 02 15.0, Dec -56 55 37, just off the northwestern rim of the galaxy listed above, and there is nothing else nearby, so the identification is certain.
Physical Information: Apparent size 1.0 by 0.7 arcmin.

IC 4808 (= PGC 62686)
Discovered (May 1900) by
DeLisle Stewart
A magnitude 12.3 spiral galaxy (type SA(s)c?) in Corona Australis (RA 19 01 07.5, Dec -45 18 51)
Historical Identification: Per Dreyer, IC 4808 (= DeLisle Stewart #545, 1860 RA 18 50 46, NPD 135 30) is "very faint, considerably large, considerably extended 45, a little brighter middle, suspected". The position precesses to RA 19 01 00.5, Dec -45 18 42, about 1.2 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 2.25 by 0.9 arcmin.

IC 4809 (= PGC 62733)
Discovered (Aug 13, 1901) by
DeLisle Stewart
A magnitude 14.1 spiral galaxy (type Scd?) in Pavo (RA 19 04 05.2, Dec -62 11 38)
Historical Identification: Per Dreyer, IC 4809 (= DeLisle Stewart #549, 1860 RA 18 51 06, NPD 152 22) is "extremely faint, very small, a little extended 20". The position precesses to RA 19 04 01.1, Dec -62 10 22, about 1.3 arcmin north northwest of the galaxy listed above, the description fits and there is nothing else nearby, so the identification is certain.
Physical Information: Based on a recessional velocity of 5555 km/sec, IC 4809 is about 260 million light years away. Given that and its apparent size of 0.95 by 0.55 arcmin, it is about 70 thousand light years across. Despite that, it is usually misclassified as a dwarf galaxy.

IC 4810 (= PGC 62706)
Discovered (Sep 16, 1901) by
DeLisle Stewart
A magnitude 12.6 spiral galaxy (type SAB(s)d?) in Telescopium (RA 19 02 59.6, Dec -56 09 35)
Historical Identification: Per Dreyer, IC 4810 (= DeLisle Stewart #548, 1860 RA 18 51 15, NPD 146 21) is "extremely faint, small, extremely extended 140, a little brighter middle, suspected". The position precesses to RA 19 02 56.7, Dec -56 09 28, just off the western edge of the galaxy listed above, the description fits, and there is nothing else nearby, so the identification is certain.
Physical Information: Apparent size 3.5 by 0.4 arcmin.

IC 4811 (= PGC 62760)
Discovered (September 1900) by
DeLisle Stewart
A magnitude 15.0 spiral galaxy (type Sbc?) in Pavo (RA 19 05 44.5, Dec -67 08 01)
Historical Identification: Per Dreyer, IC 4811 (= DeLisle Stewart #550, 1860 RA 18 51 29, NPD 157 19) is "most extremely faint, extremely small, round, almost stellar". The position precesses to RA 19 05 50.3, Dec -67 07 09, about an arcmin northeast of the galaxy listed above, the description is appropriate, and there is nothing else nearby, so the identification is certain.
Physical Information: Apparent size 0.85 by 0.6 arcmin.

IC 4812
Discovered (Aug 4, 1899) by
DeLisle Stewart
A double star and reflection nebula in Corona Australis (RA 19 01 03.5, Dec -37 03 37)
Historical Identification: Per Dreyer, IC 4812 (= DeLisle Stewart #547, 1860 RA 18 51 37, NPD 127 15.0) is a "7th magnitude star involved in an extremely large nebula". The position precesses to RA 19 01 04.8, Dec -37 03 37, right on the double star that lights up the reflection nebula listed above, so the identification is certain. This region is filled with gas and dust, lit up by numerous bright stars as reflection and emission nebulae, and as noted by Corwin NGC 6726, 6727 and 6729 are similar but brighter objects to the northeast of IC 4812.
Physical Information: Apparent size 10 by 7 arcmin?

IC 4813 (= PGC 62758)
Discovered (September 1900) by
DeLisle Stewart
A magnitude 13.6 spiral galaxy (type Sdm?) in Pavo (RA 19 05 41.7, Dec -66 31 19)
Historical Identification: Per Dreyer, IC 4813 (= DeLisle Stewart #551, 1860 RA 18 51 38, NPD 156 43) is "very faint, small, round". The position precesses to RA 19 05 46.9, Dec -66 31 09, within the eastern outline of the galaxy listed above, and there is nothing else nearby, so the identification is certain.
Physical Information: Based on a recessional velocity of 4400 km/sec, IC 4813 is about 205 million light years away. Given that and its apparent size of 1.4 by 1.0 arcmin, it is about 85 thousand light years across. Despite this, it is often misclassified as a dwarf galaxy.

IC 4814 (= PGC 62749)
Discovered (Sep 16, 1901) by
DeLisle Stewart
A magnitude 13.4 spiral galaxy (type Sbc?) in Pavo (RA 19 04 59.2, Dec -58 34 46)
Historical Identification: Per Dreyer, IC 4814 (= DeLisle Stewart #552, 1860 RA 18 52 49, NPD 148 56) is "most extremely faint, considerably small, considerably extended 100, suspected". The position precesses to RA 19 04 58.5, Dec -58 44 07, but there is nothing there. However, there is a galaxy almost exactly 10 arcmin to the north that perfectly fits the description, namely the one listed above. Per Thomson, this appears to be one of several objects for which Stewart made a similar error (probably due to a transcription error at some point in the reduction of his measurements). Applying a 10 arcmin correction to Stewart's (1900) coordinates and precessing to modern (J2000) coordinates yields a position of RA 19 04 57.1, Dec -58 34 16, less than 0.6 arcmin northwest of the candidate galaxy. As already noted it fits the description, and since the 10 arcmin error is not uncommon, the identification of IC 4814 with PGC 62749 seems reasonably certain.
Physical Information: Apparent size 1.3 by 0.6 arcmin.

IC 4815 (= PGC 62778)
Discovered (Aug 13, 1901) by
DeLisle Stewart
A magnitude 13.3 lenticular galaxy (type S0?) in Pavo (RA 19 06 50.6, Dec -61 42 05)
Historical Identification: Per Dreyer, IC 4815 (= DeLisle Stewart #553, 1860 RA 18 53 56, NPD 151 53) is "considerably faint, very small, round, brighter middle". The position precesses to RA 19 06 43.0, Dec -61 40 50, about 1.5 arcmin northwest of the galaxy listed above, and there is nothing else nearby, so the identification seems certain.
Physical Information: Apparent size 1.1 by 0.75 arcmin.

IC 4816, Nova Sagittarii 1898
Recorded (1899) by
Williamina Fleming
A nova in Sagittarius (RA 19 01 50.6, Dec -13 09 42)
and not a (nonexistent) spiral galaxy at RA 19 01 44.4, Dec -13 08 50 (which is actually a star)
Historical Identification: Per Dreyer, IC 4816 (= Fleming #81, 1860 RA 18 53 57, NPD 103 21) is "planetary, stellar". The position precesses to RA 19 01 50.0, Dec -13 09 19, just south of a 15th magnitude double star, but the double is not Fleming's object, which was the fading remnant of Nova Sagittarii 1898. As in the case of other novae recorded by Dreyer because Fleming observed gaseous emission lines in their spectra, Harvard astronomers observed the object for several years, and very early on published a precise position that precesses to the position listed above, about 0.4 arcmin south of Fleming's position (and a little further south of the aforementioned double star). If the object were still easily observable (for instance, if it were a planetary nebula), its identification would be as obvious as it is certain. Unfortunately, despite the accuracy of the published position, IC 4816 is sometimes misidentified as a nonexistent spiral galaxy at RA 19 01 44.4, Dec -13 08 50, which as noted in the warning at the start of this entry is merely another star (and like the 15th magnitude double, is not what Fleming observed).
Physical Information: At its peak the nova reached magnitude 4.5, but (per Position of Nova Sagittarii, in the Astrophysical Journal of 1899) by April 29, 1898 it had faded to 8th magnitude, and by March 20, 1899 to 11th magnitude. Presuming that the star shown in the images below is the nova, it is now perhaps 18th magnitude.

IC 4817 (= PGC 62771)
Discovered (Sep 16, 1901) by
DeLisle Stewart
A magnitude 13.6 spiral galaxy (type SAB(r)bc pec?) in Telescopium (RA 19 06 12.3, Dec -56 09 33)
Historical Identification: Per Dreyer, IC 4817 (= DeLisle Stewart #555, 1860 RA 18 54 27, NPD 146 21) is "extremely faint, very small, considerably extended 0". The position precesses to RA 19 06 07.7, Dec -56 08 50, just under an arcmin northwest of the galaxy listed above, which fits the description reasonably well. There is another galaxy (PGC 62775) close by to the east, but its lower surface brightness and fainter nucleus mean that if Stewart had seen it, he would almost certainly have seen both galaxies and made some mention of it (such as "double nucleus"). Since he didn't, the identification of IC 4817 as PGC 62771 is essentially certain.
Physical Information: Apparent size 1.65 by 0.55 arcmin. PGC 62775 is an apparent companion of IC 4817, and since their recessional velocities only differ by 400 km/sec, it is possible (though not at all certain) that they are also physical companions.

DeLisle Stewart
A magnitude 14.3 lenticular galaxy (type (R')SB0(r)a?) in Telescopium (RA 19 06 02.9, Dec -55 08 12)
Historical Identification: Per Dreyer, IC 4818 (= DeLisle Stewart #554, 1860 RA 18 54 30, NPD 145 18) is "extremely faint, extremely small, considerably extended 90". The position precesses to RA 19 06 00.3, Dec -55 05 51, nearly 2.4 arcmin north of the galaxy listed above, but the description fits and there is nothing else nearby, so the identification seems certain.
Physical Information: Apparent size 1.4 by 0.3 arcmin.

IC 4819 (= PGC 62782)
Discovered (Sep 16, 1901) by
DeLisle Stewart
A magnitude 13.4 spiral galaxy (type Scd?) in Pavo (RA 19 07 07.5, Dec -59 28 02)
Historical Identification: Per Dreyer, IC 4819 (= DeLisle Stewart #556, 1860 RA 18 54 47, NPD 149 40) is "very faint, small, extremely extended 130". The position precesses to RA 19 07 04.6, Dec -59 27 43, right on the northwestern half of the galaxy, the description fits, and there is nothing else nearby, so the identification is certain.
Physical Information: Apparent size 2.8 by 0.2 arcmin.

A magnitude 14.6 spiral galaxy (type SAB(s)d?) in Pavo (RA 19 09 13.5, Dec -63 27 54)
Historical Identification: Per Dreyer, IC 4820 (= DeLisle Stewart #557, 1860 RA 18 56 01, NPD 153 40) is "most extremely faint, extremely small". The position precesses to RA 19 09 13.6, Dec -63 27 23, just north of the galaxy listed above, and there is nothing else nearby, so the identification is certain.

IC 4823 (= PGC 62894)
Discovered (Aug 13, 1901) by
DeLisle Stewart
A magnitude 13.5 lenticular galaxy (type S0/a pec?) in Pavo (RA 19 12 15.9, Dec -63 58 34)
Historical Identification: Per Dreyer, IC 4823 (= DeLisle Stewart #559, 1860 RA 18 58 52, NPD 154 13) is "very faint, very small". The position precesses to RA 19 12 12.1, Dec -63 59 48, about 1 1/4 arcmin north northeast of the galaxy listed above, and there is nothing else of significance nearby, so the identification is certain. There is an apparent companion (PGC 62891) to the southwest of PGC 62894, but it is not considered part of the IC object. However, since the fainter galaxy is usually presumed to be a physical companion of IC 4823 it is discussed in the following entry.
Physical Information: Based on a recessional velocity of 11090 km/sec, a straightforward calculation indicates that IC 4823 is about 515 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 495 million light years away at the time the light by which we see it was emitted, about 505 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 1.75 by 1.25 arcmin, the galaxy is about 250 thousand light years across.

A magnitude 15(?) lenticular galaxy (type S0 pec?) in Pavo (RA 19 12 13.8, Dec -63 59 01)
Physical Information: PGC 62891 is generally presumed to be a physical companion IC 4823 (which see for images). Their recorded recessional velocities differ by only a few km/sec, suggesting that they are at the same distance, although a nearly 1000 km/sec uncertainty in the velocity of PGC 62891 makes it impossible to say whether the two galaxies are really at the same distance based on that alone. However, it does appear that the two galaxies are intracting, in which case the 495 million light year distance of IC 4823 also applies to PGC 62891, and its apparent size of 0.6 by 0.4 arcmin corresponds to about 85 thousand light years.

IC 4824 (= PGC 62918)
Discovered (Aug 13, 1901) by
DeLisle Stewart
A magnitude 16.2 irregular galaxy (type IAB(s)m?) in Pavo (RA 19 13 13.9, Dec -62 05 19)
Historical Identification: Per Dreyer, IC 4824 (= DeLisle Stewart #562, 1860 RA 19 00 19, NPD 152 19) is "extremely faint, extremely small, double nebula". The position precesses to RA 19 13 09.3, Dec -62 05 34, just off the western rim of the galaxy listed above, its irregular structure could easily be interpreted as a double nebula, and the only other nearby object is accounted for by another of Stewart's observations, so the identification is certain. (Note: The position listed above is for IC 4824's bright western knot.)

Historical Identification: Per Dreyer, IC 4839 (= DeLisle Stewart #575, 1860 RA 19 04 08, NPD 144 52) is a "faint, nebulous star".

IC 4845 (= PGC 63081)
Discovered (Aug 13, 1901) by
DeLisle Stewart
A magnitude 11.6 spiral galaxy (type SAB(rs)ab?) in Pavo (RA 19 20 22.3, Dec -60 23 20)
Historical Identification: Per Dreyer, IC 4845 (= DeLisle Stewart #582, 1860 RA 19 07 57, NPD 150 38) is "considerably faint, brighter middle, 11th magnitude star 0.4 arcmin to southwest". The position precesses to RA 19 20 21.0, Dec -60 23 08, within the outline of the galaxy listed above, the description fits (though the star in the description is near the center of the galaxy in modern images, Stewart's plate showed only the brightest region near the nucleus, making the star appear to be west of the galaxy instead of in front of it), and there is nothing else nearby, so the identification is certain.
Physical Information: Apparent size 2.3 by 1.8 arcmin.

IC 4847 (= PGC 63160)
Discovered (September 1900) by
DeLisle Stewart
A magnitude 14.0 spiral galaxy (type (R')SAB(rs)b?) in Pavo (RA 19 23 31.9, Dec -65 30 24)
Historical Identification: Per Dreyer, IC 4847 (= DeLisle Stewart #583, 1860 RA 19 09 47, NPD 155 46) is "very faint, extremely small, round, 8.9 magnitude star 4 arcmin to southeast". The position precesses to RA 19 23 27.6, Dec -65 30 39, less than half an arcmin southwest of the galaxy listed above. The 7th magnitude star 4 arcmin to the south (though not exactly as described) is a reasonable fit to the description, and there is nothing else nearby, so the identification is certain.
Physical Information: Apparent size 0.8 by 0.6 arcmin.
