NGC 230 is a spiral galaxy located in the constellation Cetus. It was discovered in 1886 by Francis Leavenworth. [2]
NGC 125 is a lenticular galaxy located in the constellation Pisces. It is designated as subclass Sa Ring in the galaxy morphological classification scheme. It lies approximately 235 million light-years away.
NGC 128 is a lenticular galaxy in the constellation Pisces. It is approximately 190 million light-years from the Sun and has a diameter of about 165,000 light-years.
NGC 6400 is an open cluster located in the constellation Scorpius. It is designated as II2m in the galaxy morphological classification scheme and was discovered by the Scottish astronomer James Dunlop on 13 May 1826. It is at a distance of 3,097 light years away from Earth.
NGC 169 is an unbarred spiral galaxy located in the constellation Andromeda. It was discovered on September 18, 1857, by R. J. Mitchell.
NGC 183 is an elliptical galaxy located in the constellation Andromeda. It was discovered on November 5, 1866, by Truman Safford.
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 229 is a lenticular galaxy located in the constellation Andromeda. It was discovered on October 10, 1879, by Édouard Stephan.
NGC 233 is an elliptical galaxy located in the constellation Andromeda. It was discovered on September 11, 1784 by William Herschel.
NGC 237 is a spiral galaxy located in the constellation Cetus. It was discovered on September 27, 1867 by Truman Safford.
NGC 243 is a lenticular galaxy located in the constellation Andromeda. It was discovered on October 18, 1881 by Édouard Stephan.
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 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 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 304 is a lenticular galaxy in the constellation Andromeda. It was discovered on October 23, 1878, by Édouard Stephan.
NGC 315 is an elliptical galaxy in the constellation Pisces. Its velocity with respect to the cosmic microwave background is 4635 ± 22 km/s, which corresponds to a Hubble distance of 223.0 ± 15.7 Mly (68.36 ± 4.80 Mpc). In addition, eight non-redshift measurements give a distance of 208.58 ± 22.28 Mly (63.950 ± 6.830 Mpc). It was discovered by German-British astronomer William Herschel on September 11, 1784.
NGC 318 is a lenticular galaxy in the constellation Pisces. It was discovered on November 29, 1850 by Bindon Stoney.
NGC 327 is a spiral galaxy in the constellation Cetus. It was discovered on September 27, 1864 by Albert Marth. It is described by Dreyer as "faint, small, extended." It is nearby galaxies NGC 329, NGC 325 and NGC 321.
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 366 is an open cluster located in the constellation Cassiopeia. It was discovered on October 27, 1829, by John Herschel. It was described by Dreyer as a "cluster, small."
NGC 375 is an elliptical galaxy located in the constellation Pisces. It was discovered on September 12, 1784 by William Herschel. It was described by Dreyer as "pretty faint, small, round, brighter middle." Along with galaxies NGC 379, NGC 380, NGC 382, NGC 383, NGC 384, NGC 385, NGC 386, NGC 387 and NGC 388, NGC 375 forms a galaxy cluster called Arp 331.
