NGC 440 is a spiral galaxy of type SA(s)bc pec located in the constellation Tucana. It was discovered on September 27, 1834 by John Herschel. It was described by Dreyer as "faint, very small, round." [2]
NGC 7318 is a pair of colliding galaxies about 280 million light-years from Earth. They appear in the Constellation Pegasus and are members of Stephan's Quintet.
Arp 299 is a pair of colliding galaxies approximately 134 million light-years away in the constellation Ursa Major. Both of the galaxies involved in the collision are barred irregular galaxies.
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 78 is a pair of galaxies in the constellation Pisces. NGC 78A, which is the more southern galaxy, is a barred spiral galaxy. NGC 78B, which is the more northern galaxy, is an elliptical galaxy. Although the designations NGC 78A and 78B are used today, the designation NGC 78 was formerly used mainly for the northern galaxy.
NGC 3198, also known as Herschel 146 is a barred spiral galaxy in the constellation Ursa Major. It was discovered by William Parsons, 3rd Earl of Rosse, sometime before 1850. NGC 3198 is located in the Leo Spur, which is part of the Virgo Supercluster, and is approximately 47 million light years away.
NGC 6120 is a peculiar spiral galaxy located roughly 440 million light-years away from the Sun. It is located in the northern constellation of Corona Borealis, and is a member of the Abell 2199 galaxy cluster.
NGC 146 is a small open cluster in the constellation Cassiopeia. It was discovered by John Herschel in 1829 using his father's 18.7 inch reflecting telescope.
NGC 237 is a spiral galaxy located in the constellation Cetus. It was discovered on September 27, 1867 by Truman Safford.
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 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 327 is a spiral galaxy in the constellation Cetus. Also known as "The Jamie Smith Star" (ISD0534203) and 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 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.
NGC 380 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, suddenly brighter middle." Along with galaxies NGC 375, NGC 379, NGC 382, NGC 383, NGC 384, NGC 385, NGC 386, NGC 387 and NGC 388, NGC 380 forms a galaxy cluster called Arp 331.
NGC 386 is an elliptical galaxy located in the constellation Pisces. It was discovered on November 4, 1850, by Bindon Stoney. It was described by Dreyer as "considerably faint, small, round." Along with galaxies NGC 375, NGC 379, NGC 382, NGC 383, NGC 384, NGC 385, NGC 387 and NGC 388, NGC 386 forms a galaxy cluster called Arp 331.
NGC 410 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 bright, pretty large, northeastern of 2.", the other being NGC 407.
NGC 966 is an unbarred lenticular galaxy approximately 440 million light-years away from Earth in the constellation of Cetus. It was discovered by American astronomer Francis Preserved Leavenworth in 1886.
NGC 3923 is an elliptical galaxy located in the constellation Hydra. It is located at a distance of circa 90 million light years from Earth, which, given its apparent dimensions, means that NGC 3923 is about 155,000 light years across. NGC 3923 is an example of a shell galaxy where the stars in its halo are arranged in layers. It has more than twenty shells. It was discovered by William Herschel on March 7, 1791.
NGC 3558 is an elliptical or a lenticular galaxy located 440 million light-years away in the constellation Ursa Major. It was discovered by the astronomer Heinrich d'Arrest on April 15, 1866. It is a member of the galaxy cluster Abell 1185 and is classified as a LINER galaxy.
NGC 1380 is a lenticular galaxy located in the constellation Fornax. It is located at a distance of circa 60 million light years from Earth, which, given its apparent dimensions, means that NGC 1380 is about 85,000 light years across. It was discovered by James Dunlop on September 2, 1826. It is a member of the Fornax Cluster.
NGC 1386 is a spiral galaxy located in the constellation Eridanus. It is located at a distance of circa 53 million light years from Earth, which, given its apparent dimensions, means that NGC 1386 is about 50,000 light years across. It is a Seyfert galaxy, the only one in Fornax Cluster.
