IC 1483 (= PGC 71242 = PGC 71246, and probably =
NGC 7638)
Discovered (August 8, 1880) by Andrew Common (and later listed as NGC 7638)
Discovered (Dec 2, 1893) by Stephane Javelle (and later listed as IC 1483)
A magnitude 14.9 spiral galaxy (type SB(s)dm? pec) in Pegasus (RA 23 22 33.1, Dec +11 19 46)
Historical Information: Per Dreyer, IC 1483 (Javelle #798, 1860 RA 23 15 29, NPD 79 26.3) is "faint, small, a little brighter middle." The position precesses to RA 23 22 32.9, Dec +11 19 44, almost dead center on the galaxy listed above, the description fits and there is nothing comparable nearby, so the identification as IC 1483 is certain.
Identification As NGC 7638: Steinicke, Corwin and Gottlieb all consider the identification of NGC 7638 as IC 1483 certain, thanks to its being the westernmost of the two brightest objects in the region more or less vaguely corresponnding to NGC 7638 and 7639. Because of that, the galaxy is usually discussed as if it is NGC 7638, and its IC designation is merely a footnote; but although that is probably correct there are arguments that could be made against it, so I have decided to discuss the galaxy's properties here, and only discuss the possibility that it is NGC 7638 at the NGC entry.
Physical Information: Based on a recessional velocity relative to the Cosmic Background Radiation of 7500 km/sec (and H0 = 70 km/sec/Mpc), a straightforward calculation indicates that IC 1483 is about 350 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 340 million light years away at the time the light by which we see it was emitted, a little less than 345 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 about 0.7 by 0.65 arcmin (from the images below), the galaxy is about 70 thousand light years across.

IC 1484 (= PGC 1392792)
Discovered (Dec 2, 1893) by
Stephane Javelle
A magnitude 17.0 elliptical galaxy (type E4?) in Pegasus (RA 23 22 39.9, Dec +11 23 04)
Historical Information: Per Dreyer, IC 1484 (Javelle #799, 1860 RA 23 15 36, NPD 79 23.0) is "very faint, very small." The position precesses to RA 23 22 39.8, Dec +11 23 02, which is on the northwestern rim of the galaxy listed above, the description fits and the only comparable objects in the region are accounted for by Javelle's observations of IC 1483 and 1485, so the identification is certain.
Physical Information: Based on a recessional velocity relative to the Cosmic Background Radiation of 13035 km/sec (and H0 = 70 km/sec/Mpc), a straightforward calculation indicates that IC 1484 is about 605 to 610 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 575 to 580 million light years away at the time the light by which we see it was emitted, about 590 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 about 0.4 by 0.25 arcmin (from the images below), the galaxy is about 65 to 70 thousand light years across.

IC 1485 (= PGC 71256, and perhaps =
NGC 7639)
Probably discovered (August 8, 1880) by Andrew Common (and later listed as NGC 7639?)
Discovered (Dec 2, 1893) by Stephane Javelle (and later listed as IC 1485)
A magnitude 14.6 lenticular galaxy (type E/S0?) in Pegasus (RA 23 22 48.2, Dec +11 22 22)
Historical Information: Per Dreyer, IC 1485 (Javelle #800, 1860 RA 23 15 44, NPD 79 23.7) is "very faint, very small, round, very small nucleus." The position precesses to RA 23 22 47.9, Dec +11 22 26, well within the northwestern outline of the galaxy listed above, the description fits and there is nothing comparable nearby that isn't already accounted for by Javelle's other observations, so the identification is certain.
Physical Information: Based on a recessional velocity relative to the Cosmic Background Radiation of ? km/sec (and H0 = 70 km/sec/Mpc), a straightforward calculation indicates that ? is about ? 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 ? million light years away at the time the light by which we see it was emitted, about ? 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 about ? arcmin, the galaxy is about ? thousand light years across.

Physical Information: Per Dreyer, IC 1497 (Bigourdan #242, 1860 RA 23 24 20, NPD 78 29) is "extremely faint, (only) suspected". The second IC adds a corrected position (per Bigourdan (C.R. 1897)) of RA 23 21 46, NPD 78 47. The position precesses to RA 23 28 50.5, Dec +11 59 14, but there is nothing there save for a very faint spiral galaxy less than 2 1/2 arcmin to the northeast. However, given the description, it is possible that it is what Bigourdan observed. (Its position does seem to lie between his two measurements.).
