NGC 246 is a planetary nebula in the constellation Cetus. It is the first known planetary nebula to have a hierarchical triple star system at its center. The nebula and the stars associated with it are listed in several catalogs, as summarized by the SIMBAD database. NGC 246 was discovered by William Herschel in 1785.
NGC 51 is a lenticular galaxy in the constellation Andromeda. It has a diameter of 90,000 light-years. The galaxy was discovered on September 7, 1885, by Lewis Swift, who described it as "Pretty faint, pretty small, round, brighter middle."
NGC 96 is a lenticular galaxy estimated to be about 290 million light-years away in the constellation of Andromeda. It was discovered by Guillaume Bigourdan in 1884 and its apparent magnitude is 17.
NGC 124 is a spiral galaxy in the constellation Cetus. It was discovered by Truman Henry Safford on September 23, 1867. The galaxy was described as "very faint, large, diffuse, 2 faint stars to northwest" by John Louis Emil Dreyer, the compiler of the New General Catalogue.
NGC 162 is a star in the Andromeda constellation. It was discovered by Heinrich d'Arrest in 1862. A few galaxies have been mis-identified as NGC 162.
NGC 218, also known as UGC 480, is a spiral galaxy located approximately 500 million light-years from the Sun in the constellation Andromeda. It was discovered on October 17, 1876 by Édouard Stephan, and is interacting with the galaxy PGC 2726.
SN 2013fs is a supernova, located in the spiral galaxy NGC 7610, discovered by the Intermediate Palomar Transient Factory sky survey at Palomar Observatory in October 2013. It was discovered approximately three hours from explosion and was observed in ultraviolet and X-ray wavelengths, among others, within several hours. Optical spectra were obtained beginning at six hours from explosion, making these the earliest such detailed observations ever made of a supernova.
NGC 6801 is a spiral galaxy in the constellation of Cygnus. It was discovered by Lewis A. Swift on August 5, 1886.
NGC 5837 is a barred spiral galaxy in the constellation Boötes. It was discovered on 19 June 1887 by Lewis A. Swift.
NGC 5470 is an edge-on spiral galaxy located between 43 and 68 million light-years away in the constellation Virgo. It was discovered by astronomer John Herschel in 1830. It is a member of the Virgo III Groups, a series of galaxies and galaxy clusters strung out to the east of the Virgo Supercluster of galaxies.
NGC 7038 is an intermediate spiral galaxy located about 210 million light-years away in the constellation of Indus. Astronomer John Herschel discovered NGC 7038 on September 30, 1834.
NGC 7042 is a spiral galaxy located about 210 million light-years away in the constellation of Pegasus. NGC 7042 is part of a pair of galaxies that contains the galaxy NGC 7043. Astronomer William Herschel discovered NGC 7042 on October 16, 1784.
NGC 7083 is an unbarred spiral galaxy located about 134 million light-years away in the constellation of Indus. It is also classified as a flocculent spiral galaxy. NGC 7083 was discovered by astronomer James Dunlop on August 28, 1826.
NGC 2503 is an isolated spiral galaxy approximately 254 million light-years away in the constellation Cancer. The galaxy was discovered on February 17, 1865 by astronomer Albert Marth.
NGC 4454 is a barred spiral galaxy located about 123 million light-years away in the constellation of Virgo. NGC 4454 was discovered by astronomer William Herschel on April 17, 1784.
NGC 4466 is an edge-on spiral galaxy located about 50 million light-years away in the constellation of Virgo. NGC 4466 was discovered by astronomer Bindon Stoney on February 26, 1851. The galaxy is a member of the Virgo Cluster.
NGC 4440 is a barred spiral galaxy located about 55 million light-years away in the constellation of Virgo. NGC 4440 was discovered by astronomer William Herschel on April 17, 1784. It is a member of the Virgo Cluster.
NGC 1981 is an open cluster which is located in the Orion constellation. It was discovered by John Herschel on 4 January 1827. Its apparent magnitude is 4.2 and its size is 28.00 arc minutes. It lies to the north of the Orion Nebula, separated from it by the Sh2-279 region containing NGC 1973, 1975, and 1977.
NGC 513, also occasionally referred to as PGC 5174 or UGC 953, is a spiral galaxy in the constellation Andromeda. It is located approximately 262 million light-years from the Solar System and was discovered on 13 September 1784 by astronomer William Herschel.
NGC 3199 is an emission nebula in the constellation Carina. It is commonly known as the Banana Nebula. The object was discovered in 1826 by the Scottish astronomer James Dunlop. It was thought to be the bow shock around the central star, WR 18, an especially hot and luminous Wolf–Rayet star; however, it was determined that the nebula formed due to the composition of local space, not because of the star's movement.
