NGC 2240 is an open cluster in the constellation Auriga. It was discovered by William Herschel on January 3, 1786, [1] and is located about 5.1 thousand light-years away.
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.
82 (eighty-two) is the natural number following 81 and preceding 83.
NGC 1 is an intermediate spiral galaxy of the morphological type Sbc, located in the constellation of Pegasus. It was discovered on 30 September 1861 by Heinrich d'Arrest.
NGC 3 is a lenticular galaxy with the morphological type of S0, located in the constellation of Pisces. Other sources classify NGC 3 as a barred spiral galaxy as a type of SBa. It was discovered on November 29, 1864, by Albert Marth.
NGC 206 is a bright star cloud in the Andromeda Galaxy, and the brightest star cloud in Andromeda when viewed from Earth.
NGC 7027, also known as the Jewel Bug Nebula, is a very young and dense planetary nebula located around 3,000 light-years from Earth in the constellation Cygnus. Discovered in 1878 by Édouard Stephan using the 800 mm (31 in) reflector at Marseille Observatory, it is one of the smallest planetary nebulae and by far the most extensively studied.
NGC 147 is a dwarf spheroidal galaxy about 2.58 Mly away in the constellation Cassiopeia. NGC 147 is a member of the Local group of galaxies and a satellite galaxy of the Andromeda Galaxy (M31). It forms a physical pair with the nearby galaxy NGC 185, another remote satellite of M31. It was discovered by John Herschel in September 1829. Visually it is both fainter and slightly larger than NGC 185. This means that NGC 147 is more difficult to see than NGC 185, which is visible in small telescopes. In the Webb Society Deep-Sky Observer's Handbook, the visual appearance of NGC 147 is described as follows:
Large, quite faint, irregularly round; it brightens in the middle to a stellar nucleus.
The electoral division of Franklin is one of the five electorates in the Tasmanian House of Assembly, located in southern Tasmania and includes Bruny Island, Kingston and the eastern shore of the Derwent River. Franklin is named after Sir John Franklin, the Arctic explorer who was Lieutenant-Governor of Van Diemen's Land (1837–43). The division shares its name and boundaries with the federal division of Franklin.
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 60 is an Sc type spiral galaxy in the Pisces constellation. NGC 60 is noticed for its unusually distorted spiral arms, which are commonly due to gravitational effects of neighboring galaxies, but there are no galaxies around NGC 60 to allow this.

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 210 is a barred spiral galaxy located roughly 67 million light-years from the Solar System in the constellation Cetus. It was discovered on October 3, 1785 by William Herschel and later added to the New General Catalogue.
NGC 67 is an elliptical galaxy located in the constellation Andromeda that was discovered on October 7, 1855, by R. J. Mitchell, who described it as "extremely faint, very small, round". The galaxy belongs to the NGC 68 group, which also contains the galaxies NGC 68, NGC 69, NGC 70, NGC 71, NGC 72, and possibly NGC 74.
NGC 68 is a lenticular galaxy, and the central member of the NGC 68 group, in the constellation Andromeda. The galaxy was discovered on September 11, 1784, by William Herschel, who observed the NGC 68 group as a single object and described it as "extremely faint, large, 3 or 4 stars plus nebulosity". As such, his reported location is between NGC 68, NGC 70, and NGC 71. By the time Dreyer looked at the galaxies to add to the NGC catalog, however, he was able to tell that the single galaxy observed by Herschel was in fact 3 adjacent galaxies, and cataloged them as NGC 68, NGC 70, and NGC 71.
NGC 156 is a double star located in the Cetus constellation. It was discovered on 1882 by Ernst Wilhelm Leberecht Tempel.
NGC 298 is a spiral galaxy in the constellation Cetus. It was discovered on September 27, 1864 by Albert Marth. NGC 298 is situated close to the celestial equator and, as such, it is at least partly visible from both hemispheres in certain times of the year. Given its B magnitude of 14.7, NGC 298 is visible with the help of a telescope having an aperture of 20 inches or more.
NGC 387 is an elliptical galaxy located in the constellation Pisces. It was discovered on December 10, 1873 by Lawrence Parsons. It was described by Dreyer as "very faint, small, round." Along with galaxies NGC 375, NGC 379, NGC 382, NGC 383, NGC 384, NGC 385, NGC 386 and NGC 388, NGC 387 forms a galaxy cluster called Arp 331.
NGC 480 is a spiral galaxy located about 546 million light-years away from Earth in the constellation Cetus. NGC 480 was discovered by American astronomer Francis Leavenworth In 1886.
