NGC 3370 (also known as UGC 5887 or Silverado Galaxy) is a spiral galaxy about 98 million light-years away in the constellation Leo. It is comparable to our Milky Way both in diameter (100,000 light years) and mass (1011 solar masses). NGC 3370 exhibits an intricate spiral arm structure surrounding a poorly defined nucleus. It is a member of the NGC 3370 Group of galaxies, which is a member of the Leo II Groups, a series of galaxies and galaxy clusters strung out from the right edge of the Virgo Supercluster.
Arp 87 is a pair of interacting galaxies, NGC 3808A and NGC 3808B. They are situated in the Leo constellation. NGC 3808A, the brighter, is a peculiar spiral galaxy, while NGC 3808B is an irregular galaxy.
NGC 24 is a spiral galaxy in the southern constellation of Sculptor, about 23.8 megalight-years distant from the Milky Way. It was discovered by British astronomer William Herschel in 1785, and measures some 40,000 light-years across. The general shape of this galaxy is specified by its morphological classification of SA(s)c, which indicates it is an unbarred spiral with no ring-like structure and moderate to loosely-wound spiral arms. This galaxy is positioned in the vicinity of the Sculptor Group, but is actually a background object that is more than three times as distant. It may form a pair with another background galaxy, NGC 45.
NGC 3041 is an intermediate barred spiral galaxy located in the constellation Leo. It is categorized as SAB(rs)c in the galaxy morphological classification scheme. It was discovered by William Herschel on 23 March 1784. The galaxy is approximately 77 million light years away from earth.
NGC 6104 is a barred spiral galaxy located in the constellation Corona Borealis. It is designated as S(R)Pec in the galaxy morphological classification scheme, though it is clearly a barred spiral, and was discovered by William Herschel on 16 May 1787. The galaxy is approximately 388 million light-years away.
NGC 6221 is a barred spiral galaxy located in the constellation Ara. In de Vaucouleurs' galaxy morphological classification scheme, it is classified as SB(s)bc and was discovered by British astronomer John Herschel on 3 May 1835. NGC 6221 is located at about 69 million light years from Earth.
NGC 131 is a spiral galaxy that was discovered on September 25, 1834, by John Herschel. This galaxy belongs in the NGC 134 group of galaxies: NGC 115, NGC 148, NGC 150, PGC 2000, IC 1555, and PGC 2044.
NGC 180 is a barred spiral galaxy located in the constellation Pisces. It was discovered on December 29, 1790 by William Herschel.
NGC 182 is a spiral galaxy with a ring structure, located in the constellation Pisces. It was discovered on December 25, 1790 by William Herschel.
NGC 198 is a spiral galaxy located in the constellation Pisces. It was discovered on December 25, 1790 by William Herschel.
NGC 200 is a spiral galaxy located in the constellation Pisces. It was discovered on December 25, 1790 by William Herschel.
NGC 226 is a spiral galaxy located approximately 216 million light-years from the Sun in the constellation Andromeda. It was discovered on December 21, 1786 by William Herschel.
NGC 245 is a spiral galaxy located in the constellation Cetus. It was discovered on October 1, 1785 by William Herschel.
NGC 271 is a barred spiral galaxy in the constellation Cetus. It was discovered on October 1, 1785 by William Herschel.
NGC 275 is a barred spiral galaxy located approximately 63 million light-years from the Solar System in the constellation Cetus. It is one of a pair of galaxies, the other being NGC 274. It was discovered on October 9, 1828, by John Herschel.
NGC 523, also known as Arp 158, from the ARP catalog is a spiral galaxy located in the constellation Andromeda. It was discovered separately by William Herschel on 13 September 1784, and by Heinrich d'Arrest on 13 August 1862. d'Arrest's discovery was listed as NGC 523, while Herschel's was listed as NGC 537; the two are one and the same. John Dreyer noted in the New General Catalogue that NGC 523 is a double nebula.
NGC 4647 is an intermediate spiral galaxy estimated to be around 63 million light-years away in the constellation of Virgo. It was discovered by astronomer William Herschel on March 15, 1784. NGC 4647 is listed along with Messier 60 as being part of a pair of galaxies called Arp 116; their designation in Halton Arp's Atlas of Peculiar Galaxies. The galaxy is located on the outskirts of the Virgo Cluster.
NGC 493, also occasionally referred to as PGC 4979 or GC 281, is a barred spiral galaxy in the constellation Cetus. It is located approximately 90 million light-years from Earth and was discovered on December 20, 1786 by astronomer William Herschel. It was later also observed by his son, John Herschel. John Dreyer, creator of the New General Catalogue, described the galaxy as "very faint, large, much extended 60°" with "a little brighter middle".
NGC 495, also occasionally referred to as PGC 5037, UGC 920 or GC 278, is a barred spiral galaxy in the constellation Pisces. It is located approximately 184 million light-years from the Solar System and was discovered on 12 September 1784 by astronomer William Herschel.
NGC 7606 is a spiral galaxy located in the constellation Aquarius. It is located at a distance of circa 100 million light years from Earth, which, given its apparent dimensions, means that NGC 7606 is about 165,000 light years across. It was discovered by William Herschel on September 28, 1785. The galaxy is included in the Herschel 400 Catalogue. It lies 45 arcminutes northeast from psi2 Aquarii. It can be seen with a 4 inch telescope but its visibility is greatly affected by light pollution.
