The New General Catalogue of Nebulae and Clusters of Stars is an astronomical catalogue of deep-sky objects compiled by John Louis Emil Dreyer in 1888. The NGC contains 7,840 objects, including galaxies, star clusters and emission nebulae. Dreyer published two supplements to the NGC in 1895 and 1908, known as the Index Catalogues, describing a further 5,386 astronomical objects. Thousands of these objects are best known by their NGC or IC numbers, which remain in widespread use.
The Caldwell catalogue is an astronomical catalogue of 109 star clusters, nebulae, and galaxies for observation by amateur astronomers. The list was compiled by Patrick Moore as a complement to the Messier catalogue.
NGC 290 is an open cluster of stars in the southern constellation of Tucana. This cluster was discovered September 5, 1826, by Scottish astronomer James Dunlop. It lies some 200,000 light years away from the Sun in the Small Magellanic Cloud galaxy. The cluster is an estimated 30–63 million years old and is around 65 light years across.
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 132 is a spiral galaxy in the constellation Cetus. Its velocity with respect to the cosmic microwave background is 5015 ± 25 km/s, which corresponds to a Hubble distance of 241.3 ± 16.9 Mly (73.97 ± 5.19 Mpc). In addition, three non redshift measurements give a distance of 250.81 ± 2.14 Mly (76.900 ± 0.656 Mpc). It was discovered on 25 December 1790 by German-British astronomer William Herschel.
NGC 170 is a lenticular galaxy located in the constellation Cetus. It was discovered on 3 November 1863 by Albert Marth.
NGC 180 is a barred spiral galaxy located in the constellation Pisces. It was discovered on December 29, 1790 by William Herschel.
NGC 209 is a lenticular galaxy located approximately 175 million light-years from the Solar System in the constellation Cetus. It was discovered on October 9, 1885, by Francis Leavenworth.
NGC 220 is an open cluster located approximately 210,000 light-years from the Sun in the Small Magellanic Cloud. It is located in the constellation Tucana. It was discovered on August 12, 1834 by John Herschel.
NGC 222 is an open cluster located approximately 210,000 light-years from the Sun in the Small Magellanic Cloud. It is located in the constellation Tucana. It was discovered on August 1, 1826 by James Dunlop.
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 276 is a barred spiral galaxy located approximately 626 million light-years from the Solar System in the constellation Cetus. It was discovered in 1886 by Frank Muller and was later also observed by DeLisle Stewart.
NGC 322 is a lenticular galaxy located approximately 318 million light-years from the Solar System in the constellation Phoenix. It was discovered on September 5, 1834 by John Herschel. It was described by Dreyer as "very faint, very small, round, a little brighter middle, 3 stars to west." It apparently seems to be interacting with PGC 95427, another galaxy.
NGC 359 is an elliptical galaxy located approximately 238 million light-years from the Solar System in the constellation Cetus. It was discovered on September 2, 1864, by Albert Marth. It was described by Dreyer as "extremely faint, very small."
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 710 is a spiral galaxy located 260 million light-years away in the constellation Andromeda. It was discovered by the Irish engineer and astronomer Bindon Blood Stoney on October 28, 1850 and is a member of the galaxy cluster Abell 262.
NGC 759 is an elliptical galaxy located 230 million light-years away in the constellation Andromeda. NGC 759 was discovered by astronomer by Heinrich d'Arrest on September 17, 1865. It is a member of Abell 262.
NGC 4561 is a barred spiral galaxy in the constellation Coma Berenices. It was discovered by German-British astronomer William Herschel on April 13, 1784. This galaxy is located at a distance of 82 ± 14 million light-years (25.2 ± 4.3 Mpc) from the Milky Way, and is a member of the Virgo Cluster of galaxies. It is 13th magnitude with an angular size of 1.5′.
NGC 803 is a spiral galaxy located in the constellation Aries about 70 million light-years from the Milky Way. It was discovered by the German–British astronomer William Herschel in 1784.
NGC 721 is a barred spiral galaxy located in the constellation Andromeda about 250 million light years from the Milky Way. It was discovered by the Prussian astronomer Heinrich d'Arrest in 1862.
