Messier 77 (M77), also known as NGC 1068 or the Squid Galaxy, is a barred spiral galaxy in the constellation Cetus. It is about 47 million light-years (14 Mpc) away from Earth, and was discovered by Pierre Méchain in 1780, who originally described it as a nebula. Méchain then communicated his discovery to Charles Messier, who subsequently listed the object in his catalog. Both Messier and William Herschel described this galaxy as a star cluster. Today, however, the object is known to be a galaxy. It is one of the brightest Seyfert galaxies visible from Earth and has a D25 isophotal diameter of about 27.70 kiloparsecs (90,000 light-years).
NGC 2 is an intermediate spiral galaxy with the morphological type of Sab, located in the constellation of Pegasus. NGC 2 was discovered by Lawrence Parsons, 4th Earl of Rosse on 20 August 1873."
NGC 6745 is an irregular galaxy about 206 million light-years away in the constellation Lyra. It was discovered by French astronomer Édouard Stephan on 24 July 1879.
NGC 3310 is a grand design spiral galaxy in the constellation Ursa Major. It is a starburst galaxy and it is likely that NGC 3310 collided with one of its satellite galaxies about 100 million years ago, triggering widespread star formation. It is thought to be located approximately 46 million light-years away from the Earth, and is thought to be about 22,000 light-years wide.
NGC 1410 is a peculiar lenticular galaxy in the constellation Taurus. It was discovered on January 17, 1855, by English astronomer R. J. Mitchell. NGC 1410 is located in close proximity to the larger lenticular galaxy NGC 1409, and the two are strongly interacting. Their respective nuclei have a separation of just 23 kly, and they share a diffuse stellar envelope with a radius extending out to 49 kly.
NGC 5749 is an open cluster of stars positioned near the southwest border of the southern constellation of Lupus. It is located at a distance of 3,548 light years from the Sun. This is a poorly populated cluster that shows a low level of concentration; the Trumpler class is IV1p. There are 112 stars brighter than magnitude 14.4 within an angular radius of ~15′ of the cluster center, but only about 30% of these are members. NGC 5749 is 27 million years old with a tidal radius of 11.7 light years and a mass of ~21 M☉. Polarization measurements suggest there is a dust cloud within the cluster.
NGC 243 is a lenticular galaxy located in the constellation Andromeda. It was discovered on October 18, 1881 by Édouard Stephan.
NGC 244 is a lenticular galaxy located in the constellation Cetus. It was discovered on December 30, 1785 by William Herschel.
NGC 261 is a diffuse nebula located in the constellation Tucana. It was discovered on September 5, 1826, by James Dunlop.
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 274 is a lenticular galaxy in the constellation Cetus. It is a pair of galaxies, the other being NGC 275, which it is currently interacting with. It was discovered on September 10, 1785 by William Herschel. It is roughly 120 million light-years away.
NGC 283 is a spiral galaxy in the constellation Cetus. It was discovered on October 2, 1886, by Francis Leavenworth.
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 318 is a lenticular galaxy in the constellation Pisces. It was discovered on November 29, 1850 by Bindon Stoney.
NGC 338 is a spiral galaxy in the constellation Pisces. Its velocity with respect to the cosmic microwave background is 4479 ± 22 km/s, which corresponds to a Hubble distance of 215.5 ± 15.1 Mly (66.07 ± 4.64 Mpc). In addition, 22 non-redshift measurements give a distance of 223.56 ± 5.04 Mly (68.545 ± 1.544 Mpc). It was discovered in 1877 by Wilhelm Tempel. It was described by Dreyer as "very faint, very small, irregular figure, brighter middle."
NGC 353 is a spiral galaxy in the constellation Cetus. It was discovered on November 10, 1885 by Lewis Swift. It was described by Dreyer as "extremely faint, pretty small, round, southeastern of 2.", the other being NGC 351.
NGC 385 is an unbarred lenticular galaxy located in the constellation Pisces. It was discovered on November 4, 1850, by Bindon Stoney. It was described by Dreyer as "pretty faint, pretty small, round, northeastern of 2.", the other being NGC 384. Along with galaxies NGC 375, NGC 379, NGC 382, NGC 383, NGC 384, NGC 386, NGC 387 and NGC 388, NGC 385 forms a galaxy cluster called Arp 331.
