NGC 283 is a spiral galaxy in the constellation Cetus. It was discovered on October 2, 1886, by Francis Leavenworth. [2]
Messier 102 is a galaxy listed in the Messier Catalogue that cannot be unambiguously identified. Its original discoverer Pierre Méchain retracted his discovery two years after publication and said that it was a duplicate observation of Messier 101. Later historical evidence favors that M102 is actually the galaxy NGC 5866, although other galaxies have been suggested as possible identities. The National Aeronautics and Space Administration (NASA) considers it to be the same as NGC 5866.
NGC 2438 is a planetary nebula in the southern constellation of Puppis. Parallax measurements by Gaia put the central star at a distance of roughly 1,370 light years. It was discovered by William Herschel on March 19, 1786. NGC 2438 appears to lie within the cluster M46, but it is most likely unrelated since it does not share the cluster's radial velocity.
NGC 5334 is a face-on barred spiral galaxy in the constellation Virgo. Its velocity with respect to the cosmic microwave background is 1668 ± 20 km/s, which corresponds to a Hubble distance of 80.2 ± 5.7 Mly (24.60 ± 1.75 Mpc). However, five non-redshift measurements give a distance of 108.68 ± 7.45 Mly (33.320 ± 2.283 Mpc). It was discovered by German-British astronomer William Herschel on 15 April 1787. It was also observed by American astronomer Lewis Swift on 20 April 1897 and listed in the Index Catalogue as IC 4338.
The Collinder catalogue is a catalogue of 471 open clusters compiled by Swedish astronomer Per Collinder. It was published in 1931 as an appendix to Collinder's paper On structural properties of open galactic clusters and their spatial distribution.
NGC 9 is a spiral galaxy about 140 million light-years away in the Pegasus constellation. It was discovered on 27 September 1865 by Otto Wilhelm von Struve.
NGC 243 is a lenticular galaxy located in the constellation Andromeda. It was discovered on October 18, 1881 by Édouard Stephan.
NGC 266 is a massive barred spiral galaxy in the constellation Pisces. NGC 266 is located at a distance of 197 megalight-years from the Milky Way. It was discovered on September 12, 1784, by William Herschel. The form of this barred galaxy is described by its morphological classification of SB(rs)ab, which indicates a quasi-ring-like structure (rs) and moderate-to-tightly wound spiral arms (ab).
NGC 267 is an open cluster in the Small Magellanic Cloud. It is located in the constellation Tucana. It was discovered on October 4, 1836, by John 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 285 is a lenticular galaxy in the constellation Cetus. It was discovered on October 2, 1886, by Francis Leavenworth.
NGC 286 is a lenticular galaxy in the constellation Cetus. It was discovered on October 2, 1886 by Francis Leavenworth.
NGC 297 is an elliptical galaxy in the constellation Cetus. It was discovered on September 27, 1864, by Albert Marth and is classified as type E3, based on galaxy morphological classification.
NGC 304 is a lenticular galaxy in the constellation Andromeda. It was discovered on October 23, 1878, by Édouard Stephan.
NGC 317 is a pair of interacting galaxies, consisting of a lenticular galaxy NGC 317A and a spiral galaxy NGC 317B, in the constellation Andromeda. It was discovered on October 1, 1885 by Lewis Swift.
NGC 323 is an elliptical galaxy located in the constellation Phoenix. It was discovered on October 3, 1834, by John Herschel. It was described by Dreyer as "pretty faint, small, round, brighter middle, preceding (western) of 2", the other being NGC 328.
NGC 6540 is a globular cluster of stars in the souther constellation Sagittarius, positioned about 4.66° away from the Galactic Center. It was discovered by German-British astronomer Wilhelm Herschel on May 24, 1784, with an 18.7-inch mirror telescope, who described the cluster as "pretty faint, not large, crookedly extended, easily resolvable". It has an apparent visual magnitude of 9.3 with an angular diameter of about 9.5 arcminutes.
NGC 478 is a spiral galaxy in the constellation Cetus. It is located approximately 283 million light-years from Earth and was discovered in 1886 by astronomer Francis Preserved Leavenworth.
NGC 753 is a spiral galaxy located 220 million light-years away in the constellation Andromeda. The galaxy was discovered by astronomer by Heinrich d'Arrest on September 16, 1865 and is a member of Abell 262.
NGC 2798 is a barred spiral galaxy in the constellation Lynx. NGC 2798 and NGC 2799 are listed under the Arp Catalogue as Arp 283 and noted as an "interacting galaxy pair". The galaxy is listed in the New General Catalogue.
