NGC 1409 is a quiescent [4] lenticular galaxy in the equatorial constellation of Taurus. It was discovered by the German-born astronomer William Herschel on January 6, 1785. [6] NGC 1409 is located in close proximity to the smaller Seyfert galaxy NGC 1410, and the two are strongly interacting. Their respective nuclei have a separation of just 23 kly, and they share a diffuse stellar envelope with a radius extending out to 49 kly. [4]
The morphological classification of this galaxy most closely matches type SB0, which indicates a barred lenticular galaxy. There is a conspicuous pipeline of dust and gas being funneled to NGC 1409 from NGC 1410. This lane has a typical width of 330 ly, passing to the north in front of NGC 1409 and then behind, becoming denser toward the galactic core. It has an estimated mass of 3×108 M☉ and is transferring mass at the estimated rate of 1.1–1.4 M☉ yr–1. However, there is no indications of recent star formation in NGC 1409 from this incoming material. [4]
NGC 1705 is a peculiar lenticular galaxy and a blue compact dwarf galaxy (BCD) in the southern constellation of Pictor, positioned less than a degree to the east of Iota Pictoris, and is undergoing a starburst. With an apparent visual magnitude of 12.6 it requires a telescope to observe. It is estimated to be approximately 17 million light-years from the Earth, and is a member of the Dorado Group.
NGC 4526 is a lenticular galaxy with an embedded dusty disc, located approximately 55 million light-years from the Solar System in the Virgo constellation and discovered on 13 April 1784 by William Herschel.
NGC 1410 is a peculiar lenticular galaxy in the constellation Taurus. It was discovered on January 17, 1855, by English astronomer R. J. Mitchell. NGC 1410 is located in close proximity to the larger lenticular galaxy NGC 1409, and the two are strongly interacting. Their respective nuclei have a separation of just 23 kly, and they share a diffuse stellar envelope with a radius extending out to 49 kly.
NGC 5820 is a lenticular galaxy in the constellation Boötes. It lies near NGC 5821, a galaxy with a similar mass at the same redshift.
NGC 5929 is a Seyfert galaxy in the constellation Boötes. The pair of galaxies, NGC 5929 and NGC 5930, are interacting.
NGC 5613 is a lenticular galaxy in the constellation Boötes. It is part of the Arp 178 set of interacting galaxies, with NGC 5615 and NGC 5614.
NGC 5755 is a barred spiral galaxy in the constellation Boötes, member of Arp 297 interacting galaxies group of four: NGC 5752, NGC 5753, NGC 5754, and NGC 5755.
NGC 5890 is an unbarred lenticular galaxy in the constellation Libra. It was discovered in April 1785 by Ormond Stone.
NGC 3539 is a lenticular galaxy in the constellation Ursa Major. It was discovered in April 1831 by John Herschel. It is a member of the galaxy cluster Abell 1185.
NGC 42 is a lenticular galaxy in the Pegasus constellation. It was discovered on October 30, 1864, by the German astronomer Albert Marth. It may be gravitationally interacting with the nearby NGC 41.

NGC 4866 is an unbarred lenticular galaxy located roughly 100 million light-years away in the constellation Virgo. It was first observed by British astronomer Sir William Herschel on January 14, 1787. It is a member of the Virgo Cluster.
NGC 3718, also called Arp 214, is a galaxy located approximately 52 million light years from Earth in the constellation Ursa Major. It is either a lenticular or spiral galaxy.
NGC 85 is an interacting spiral or lenticular galaxy estimated to be about 200 million light-years away in the constellation of Andromeda. It was discovered by Ralph Copeland in 1873 and its apparent magnitude is 15.7. The galaxy appears to be interacting with the companion spiral IC 1546.
NGC 4138 is the New General Catalogue identifier for a lenticular galaxy in the northern constellation of Canes Venatici. Located around 52 million light years from Earth, it spans some 2.1 × 1.3 arc minutes and has an apparent visual magnitude of 11.3. The morphological classification of NGC 4138 is SA0+(r), indicating it lacks a bar formation and has tightly wound spiral arms with a ring-like structure around the nucleus. It has no nearby companion galaxies.
NGC 4147 is the New General Catalogue identifier for a globular cluster of stars in the northern constellation of Coma Berenices. It was discovered by English astronomer William Herschel on March 14, 1784, who described it as "very bright, pretty large, gradually brighter in the middle". With an apparent visual magnitude of 10.7, it is located around 60,000 light years away from the Sun at a relatively high galactic latitude of 77.2°.
NGC 5026 is a barred spiral galaxy or lenticular galaxy in the constellation of Centaurus. It was discovered on 5 June 1834 by John Herschel. It was described as "pretty bright, pretty large, round, gradually brighter middle" by John Louis Emil Dreyer, the compiler of the New General Catalogue.
NGC 1326 is a lenticular galaxy in the constellation Fornax, 63 million light-years away. It was discovered by English astronomer John Herschel on 29 November 1837. It is a member of the Fornax Cluster, an NGC 1316 subgroup and has a diameter of 70 000 light-years.
NGC 5422 is a lenticular galaxy located in the constellation Ursa Major. It was discovered on April 14, 1789 by the astronomer William Herschel.
