NGC 3750 (= PGC 36011 = HCG 57C), part of the Copeland Septet
(also part of
Hickson Compact Group 57 and Arp 320)
Discovered (Feb 9, 1874) by Ralph Copeland
A 14th-magnitude lenticular galaxy (type E/S0?) in Leo (RA 11 37 51.6, Dec +21 58 28)
Historical Identification: Per the first IC note for NGC 3745, the RA should be increased by 1m 32s, and the NPD reduced by 15.9 arcmin.
Arp 320 Note: Used by the Arp Atlas as a member of a group of galaxies. Definitely meant to be part of Arp 320, as it is one of the triplet of galaxies mentioned in Arp's comment about the group.
Physical Information: Apparent size 0.5 by 0.4 arcmin?

NGC 3751 (= PGC 36017 = HCG 57F), part of the Copeland Septet
(also part of
Hickson Compact Group 57, but not part of Arp 320)
Discovered (Apr 5, 1874) by Ralph Copeland
A 14th-magnitude lenticular galaxy (type E/S0?) in Leo (RA 11 37 53.9, Dec +21 56 11)
Part of the Copeland Septet (= Hickson Compact Group 57). Per the first IC note for NGC 3745, the RA should be increased by 1m 32s, and the NPD reduced by 15.9 arcmin.
Note About Arp 320: Arp 320 is usually listed as being Copeland's Septet, because almost all of the galaxies in the Septet are in the field of view of Arp 320. But the Arp Atlas image does not show NGC 3751, so it is not part of Arp 320, and any statement that it is is in error.

NGC 3758, the Owl Galaxy
(= PGC 35905 = PGC 165579 = CGCG 126-110 = MCG +04-27-073)

Discovered (Mar 18, 1874) by
Ralph Copeland
Independently discovered (Mar 18, 1884) by Édouard Stephan
A magnitude 14.3 spiral galaxy (type Sab? pec) in Leo (RA 11 36 29.2, Dec +21 35 46)
The eastern nucleus is at RA 11 36 29.4, Dec +21 35 46, the western is at RA 11 36 28.9, Dec +21 35 47
Historical Identification: Per Dreyer, NGC 3758 (Copeland (using Lord Rosse's 72-inch telescope), Stephan list XIII (#61), 1860 RA 11 29 10, NPD 67 37.8) is "pretty bright, small, round, brighter middle, 8.5 magnitude star 3 arcmin to east." The position precesses to RA 11 36 29.2, Dec +21 35 46, essentially dead center on the galaxy listed above, the description fits and there is nothing else nearby, so the identification is certain.
Physical Information: NGC 3758 is the result of the merger of two galaxies, the nuclei of which are still clearly separated from each other, so it is in a fairly early stage of merging. Each nucleus contains a supermassive black hole, and when the galaxy finishes merging there is a good chance that the black holes will merge, producing spectacular optical and gravitational effects. However, this will be in the far distant future, so it isn't likely that there will be any humans around to observe the results. The eastern nucleus is classed as a Seyfert galaxy (type Sy1) because of its exceptionally bright center.
 Based on a recessional velocity relative to the Cosmic Background Radiation of 9275 km/sec (and H0 = 70 km/sec/Mpc), a straightforward calculation indicates that NGC 3758 is about 430 to 435 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 415 to 420 million light years away at the time the light by which we see it was emitted, about 420 to 425 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 0.55 by 0.45 arcmin for the main galaxy, and something in excess of 1.2 by 0.55 for faint outer arms (from the images below), the main galaxy is about 65 to 70 thousand light years across, and its outer arms span at least 145 thousand light years, and since the ESO image only shows part of the outer arms, their extent is probably closer to 200 thousand light years.
Classification Note: Given its incomplete merger and the resulting peculiarities in the appearance of the galaxy, any normal classification is essentially meaningless; but there seems to be general agreement that the best description is as shown above, with the emphasis on "peculiar", and a very big question mark for any other part of the description.

NGC 3799 (= PGC 36193, and with
NGC 3800 = Arp 83)
Discovered (Apr 21, 1832) by John Herschel
A 14th-magnitude spiral galaxy (type SB(s)b? pec) in Leo (RA 11 40 09.3, Dec +15 19 39)
Based on a recessional velocity of 3310 km/sec (which happens to be the same as that listed by NED for its apparent companion, NGC 3800), NGC 3799 is about 155 million light years away. Given that and its apparent size of 0.8 by 0.5 arcmin, it is about 35 thousand light years across.
