NGC 54

NGC 54 is an edge-on spiral galaxy in the constellation of Cetus. The galaxy was discovered by Wilhelm Tempel in 1886, and he defined it as "very faint, pretty small, round." The galaxy is 90,000 light years in diameter, making it slightly smaller than the Milky Way.

NGC 459

NGC 459, also known as UGC 832, MCG 3-4-17, ZWG 459.24, and PGC 4665, is a spiral galaxy in the constellation Pisces. It was discovered on October 15, 1784, by William Herschel. It was described as being extremely faint by John Dreyer in the New General Catalogue.

NGC 482

NGC 482 is a spiral galaxy in the constellation Phoenix. It is located approximately 277 million light-years from Earth and was discovered on October 23, 1835 by astronomer John Herschel.

NGC 483

NGC 483 is a spiral galaxy in the constellation Pisces. It is located approximately 192 million light-years from Earth and was discovered on November 11, 1827 by astronomer John Herschel.

NGC 485 Spiral galaxy in the constellation Pisces

NGC 485, also commonly referred to as PGC 4921 or GC 270, is a spiral galaxy in the constellation Pisces. It is located approximately 86 million light-years from Earth and was discovered on January 8, 1828 by astronomer William Herschel. It was later also observed by Heinrich d'Arrest and Herman Schultz. When NGC 485 was originally categorized in the New General Catalogue by John Louis Eil Dreyer in 1888, it was incorrectly described as a "considerably faint, pretty large, round, 8th magnitude star 3 1/2 arcmin to southwest".

NGC 486

NGC 486, also occasionally referred to as LEDA 1281966 or GC 275, is a spiral galaxy in the constellation Pisces. NGC 486 was discovered on December 6, 1850 by Irish engineer Bindon Blood Stoney.

NGC 492

NGC 492, also occasionally referred to as PGC 4976 or GC 280, is a barred spiral galaxy in the constellation Pisces. It is located approximately 590 million light-years from Earth and was discovered on December 6, 1850 by Irish engineer Bindon Blood Stoney. Although John Dreyer, creator of the New General Catalogue, credits the discovery to astronomer William Parsons, 3rd Earl of Rosse, he notes that many of his claimed discoveries were made by one of his assistants. In the case of NGC 492, the discovery was made by Bindon Stoney, who discovered it along with NGC 486, NGC 490 and NGC 500 during his observation of NGC 488 using Lord Rosse's 72" telescope.

NGC 493

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 494

NGC 494, also occasionally referred to as PGC 5035 or GC 282, is a barred spiral galaxy in the constellation Pisces. It is located approximately 227 million light-years from Earth and was discovered on 22 November 1827 by astronomer John Herschel. John Dreyer, creator of the New General Catalogue, described the galaxy as "very faint, pretty large, extended, 3 faint stars to south".

NGC 495

NGC 495, also occasionally referred to as PGC 5037, UGC 920 or GC 278, is a barred spiral galaxy in the constellation Pisces. It located approximately 184 million light-years from the Solar System and was discovered on 12 September 1784 by astronomer William Herschel.
