3C 305, also known as IC 1065, is a lenticular galaxy located in the constellation Draco. [3] [1] [2] It has an active galactic nucleus and is classified both a Seyfert 2 and radio galaxy [1] [2] The galaxy was discovered by American astronomer Lewis Swift when he came upon it on April 7th, 1888.

Draco is a constellation in the far northern sky. Its name is Latin for dragon. It was one of the 48 constellations listed by the 2nd century Greek astronomer Ptolemy, and remains one of the 88 modern constellations today. The north pole of the ecliptic is in Draco. Draco is circumpolar from northern latitudes, meaning that it never sets and can be seen at any time of year.
3C 249.1 is a Seyfert galaxy located in the constellation Draco.
3C 319 is a radio galaxy located in the constellation Draco.
3C 371 is a BL Lac object located in the constellation Draco. With a redshift of 0.051, this active galaxy is about 730 million light-years away.
IC 335 is an edge-on lenticular galaxy about 60 million light years away, in the constellation Fornax. It is part of the Fornax Cluster.
NGC 3862 is an elliptical galaxy located 300 million light-years away in the constellation Leo. Discovered by astronomer William Herschel on April 27, 1785, NGC 3862 is an outlying member of the Leo Cluster.
IC 2006 is an elliptical galaxy in the constellation Eridanus. The galaxy was discovered on 3 October 1897 by the American astronomer Lewis A. Swift. It is estimated to be around 60 to 70 million light years away, in the Fornax Cluster. The galaxy is one of the smaller in the Fornax cluster, with a diameter of only 35 000 light-years.
NGC 7302 is a lenticular galaxy located around 124 million light-years away from Earth in the constellation of Aquarius. NGC 7302 was discovered by British astronomer William Herschel on October 3, 1785 and was rediscovered by American astronomer Lewis Swift on August 8, 1896 and was listed in the IC catalogue as IC 5228. It is also part of a group of interacting galaxies.
NGC 7013 is a relatively nearby spiral or lenticular galaxy estimated to be around 37 to 41.4 million light-years away from Earth in the constellation of Cygnus. NGC 7013 was discovered by English astronomer William Herschel on July 17, 1784 and was also observed by his son, astronomer John Herschel on September 15, 1828.
NGC 7020 is a barred lenticular galaxy located about 140 million light-years away in the constellation Pavo. NGC 7020 was discovered by astronomer John Herschel on August 31, 1836.
NGC 4753 is a lenticular galaxy located about 60 million light-years away in the constellation of Virgo. NGC 4753 was discovered by astronomer William Herschel on February 22, 1784. It is notable for having distinct dust lanes that surround its nucleus. It is a member of the NGC 4753 Group of galaxies, which is a member of the Virgo II Groups, a series of galaxies and galaxy clusters strung out from the southern edge of the Virgo Supercluster.
NGC 4497 is a lenticular galaxy located about 60 million light-years away in the constellation Virgo. NGC 4497 was discovered by astronomer William Herschel on March 15, 1784. It was rediscovered by astronomer Arnold Schwassmann on November 8, 1900 and was listed as IC 3452. NGC 4497 is a member of the Virgo Cluster.
NGC 499, also occasionally referred to as PGC 5060, IC 1686 or GC 289, is a lenticular galaxy in the constellation Pisces. It is located approximately 197 million light-years from the Solar System and was discovered on 12 September, 1784 by astronomer William Herschel.
NGC 541 is a lenticular galaxy located in the constellation Cetus. It is located at a distance of about 230 million light years from Earth, which, given its apparent dimensions, means that NGC 541 is about 130,000 light years across. It was discovered by Heinrich d'Arrest on October 30, 1864. It is a member of the Abell 194 galaxy cluster and is included in the Atlas of Peculiar Galaxies in the category galaxies with nearby fragments. NGC 541 is a radio galaxy of Fanaroff–Riley class I, also known as 3C 40A.
NGC 4513 is a lenticular galaxy and a ring galaxy located about 110 million light-years away in the constellation Draco. It was discovered by astronomer Heinrich d'Arrest on October 16, 1866.
NGC 1375 is a barred lenticular galaxy in the constellation Fornax discovered by John Herschel on November 29, 1837. It is believed to be a member of the Fornax Cluster.
NGC 530, also known as IC 106, is a lenticular galaxy in the constellation Cetus. It is approximately 226 million light years from the Milky Way and has a diameter of around 100,000 light years. The object was discovered on November 20, 1886, by the American astronomer Lewis A. Swift, who listed it as NGC 530, and rediscovered on November 16, 1887, by Guillaume Bigourdan, who listed it as IC 106.
NGC 823, also known as IC 1782, is an unbarred lenticular galaxy in the constellation Fornax. It is estimated to be 194 million light-years from the Milky Way and has a diameter of approximately 100,000 light years. NGC 823 was discovered on October 14, 1830, by astronomer John Herschel.
NGC 4221 is a barred lenticular galaxy located about 75.9 million light-years away in the constellation of Draco. It was discovered on April 3, 1832, by the astronomer John Herschel. NGC 4221 is notable for having an outer ring that surrounds the inner barred central region of the galaxy.
