IC 2750 (= PGC 1368199)
Discovered (Mar 27, 1906) by Max Wolf (7-123)
A magnitude 15.7 spiral galaxy (type Sbc?) in Leo (RA 11 21 50.7, Dec +09 39 30)
Based on a recessional velocity of 22855 km/sec, a straightforward calculation indicates that IC 2750 is about 1065 million light years away. However, at that distance we must take the expansion of the Universe during the time it took the light from the galaxy to reach us into account. Doing that shows that IC 2750 was about 975 million light years away when the light by which we see it left it, about 1000 million years ago (the difference between the two numbers being due to the expansion of the intervening space during that interval). Given that and its apparent size of 0.4 by 0.2 arcmins, it is about 120 thousand light years across.

IC 2758 (= PGC 34857)
Discovered (Mar 27, 1906) by Max Wolf (7-130)
A magnitude 14.2 lenticular galaxy (type S0/a?) in Leo (RA 11 22 03.2, Dec +07 48 50)
Based on a recessional velocity of 6100 km/sec, IC 2758 is about 285 million light years away. Given that and its apparent size of 0.75 by 0.2 arcmin, it is about 60 thousand light years across. Its apparent companion ( PGC 1331600) has a similar recessional velocity, and is probably a physical companion, but the pair show no evidence of gravitational interaction, so they are almost certainly not as close as they appear.

Not an IC object but listed here since a companion of IC 2758
A magnitude 16 lenticular galaxy (type E/S0?) in Leo (RA 11 22 02.4, Dec +07 48 47)
Based on a recessional velocity of 6060 km/sec, PGC 1331600 is at almost the same (285 million light year) distance as IC 2758. Given that and its apparent size of 0.35 by 0.3 arcmin, it is about 30 thousand light years across. Its apparent companion ( IC 2758, which see for images) has a similar recessional velocity, and is probably a physical companion, but the pair show no evidence of gravitational interaction, so they are almost certainly not as close as they appear.
IC 2759 (= PGC 34881 = HCG 51E),
a member of Hickson Compact Group 51
Discovered (Apr 24, 1897) by Guillaume Bigourdan
A magnitude 14.1 lenticular galaxy (type E/SAB0?) in Leo (RA 11 22 13.3, Dec +24 19 02)
Historical Identification: Per Dreyer, IC 2759 (Bigourdan #405, 1860 RA 11 14 48, NPD 64 55) is "considerably faint, stellar, 13th magnitude star 2.5 arcmin west northwest". The position precesses to RA 11 22 13.8, Dec +24 19 00, on the eastern rim of the galaxy listed above, the description fits and the 14th magnitude star 2 arcmin west northwest makes the identification certain. However, despite that certainty, the galaxy to the south of IC 2759 ( PGC 34882) is sometimes misidentified as the IC object, hence the warning at its entry.
Physical Information: Based on a recessional velocity of 7700 km/sec, a straightforward calculation indicates that IC 2759 is 355 to 360 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 345 to 350 million light years away at the time the light by which we see it was emitted, 350 to 355 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 0.45 by 0.45 arcmin, the galaxy is about 45 thousand light years across.

A pair of galaxies in Leo
PGC 1414481 = A magnitude 16.2 spiral galaxy (type S?) at RA 11 23 27.0, Dec +12 41 53
PGC 4535618 = A magnitude 16.7 spiral galaxy (type S?) at RA 11 23 26.7, Dec +12 42 01
Per Dreyer, IC 2788 (= Wolf list VII #158, 1860 RA 11 16 09, NPD 76 32.0) is "very faint, small, round". The position precesses to RA 11 23 26.9, Dec +12 41 57, between the two galaxies listed above, so the identification is certain. The apparent size of PGC 1414481 is about 0.2 by 0.1 arcmin, and of PGC 4535618 is about 0.16 by 0.08 arcmin.

plus a magnitude 16(?) star at RA 11 23 32.8, Dec +14 11 12 11233708+1410568
Per Dreyer, IC 2789 (= Wolf list VII #159, 1860 RA 11 16 14, NPD 75 02.6) is "pretty bright, small, round, brighter middle". The position precesses to RA 11 23 32.7, Dec +14 11 21, less than 0.1 arcmin north of the star and galaxy listed above, so the identification is certain. Per Corwin, the original plate shows the two objects as a single blended image, so the IC designation belongs to the pair, and not merely one or the other. The apparent size of PGC 4098059 is about 0.10 by 0.75 arcmin.
