NGC 3748
NGC 3748 is a lenticular galaxy with a bar located in the Leo (constellation), Leo constellation. It is located 440 million light-years away from the Solar System and was discovered by Ralph Copeland on April 5, 1874, but also observed by Hermann Kobold, Lawrence Parsons, 4th Earl of Rosse, Lawrence Parsons and John Louis Emil Dreyer. Like NGC 3746, NGC 3748 also has a recessed core (RET). It is described as, "moderately bright, fairly small, slightly elongated NW-SE, 0.4'x0.3' with a small bright core". Copeland Septet NGC 3748 is a member of the Copeland Septet which is made up of 7 galaxies which were discovered by Copeland in 1874. The other members are NGC 3745, NGC 3746, NGC 3750, NGC 3751, NGC 3753 and NGC 3754. Halton Arp noticed the Galaxy, galaxies in this group in an article that was published in 1966. This group is known as Atlas of Peculiar Galaxies, Arp 320 along with another galaxy, PGC 36010. This group was observed by Paul Hickson whom he included in his art ...

NGC 3745
NGC 3745 is a lenticular galaxy with a bar structure located in the constellation of Leo (constellation), Leo. NGC 3745 is located 471 million Light-year, light-years away from the Solar System and was discovered by Ralph Copeland on April 5, 1874, but also observed by Hermann Kobold, Lawrence Parsons, 4th Earl of Rosse, Lawrence Parsons and John Louis Emil Dreyer. Copeland Septet NGC 3745 is a member of the Copeland Septet. The other members of the group are NGC 3746, NGC 3748, NGC 3750, NGC 3751, NGC 3753 and NGC 3754. Halton Arp noticed the group when he published the article in 1966. The group is designated as Atlas of Peculiar Galaxies, Arp 320 in which another galaxy PGC 36010, is part of it. This group was also observed by Paul Hickson, in which he included them inside his article in 1982.
