NGC 173 is an unbarred spiral galaxy located approximately 3.8 million light-years away in the constellation Cetus.
NGC 55, is a Magellanic type barred spiral galaxy located about 6.5 million light-years away in the constellation Sculptor. Along with its neighbor NGC 300, it is one of the closest galaxies to the Local Group, probably lying between the Milky Way and the Sculptor Group. It has an estimated mass of (2.0 ± 0.4) × 1010M☉.
NGC 514 is a low-luminosity, intermediate spiral galaxy in the equatorial constellation of Pisces, located at a distance of approximately 83 million light-years from the Milky Way. It was discovered on 16 October 1784 by astronomer William Herschel. The general form of the galaxy is specified by its morphological classification of SAB(rs)c, which indicates it has a weak bar system at the core (SAB), an incomplete ring formation around the bar (rs), and somewhat loosely-wound spiral arms (c). This galaxy has an H II nucleus with an extended region that displays weak emission lines in the optical range, but not in the near infrared. The suspected supermassive black hole at the core has an estimated mass of 3.2×106 M☉.
NGC 602 is a young, bright open cluster of stars located in the Small Magellanic Cloud (SMC), a satellite galaxy to the Milky Way. It is embedded in a nebula known as N90.
NGC 5806 is an intermediate spiral galaxy in the constellation Virgo. It was discovered on February 24, 1786, by the astronomer John Herschel. It is located about 70 million light-years away from the Milky Way. It is a member of the NGC 5846 Group.
NGC 1052 is an elliptical galaxy in the constellation Cetus. It was discovered on January 10, 1785 by the astronomer William Herschel. It is a member of the eponymous NGC 1052 Group.
NGC 3359 is a barred spiral galaxy located 59 million light-years from Earth, in the constellation of Ursa Major. It was discovered on November 28, 1793, by the astronomer William Herschel. The central bar is approximately 500 million years old.
NGC 151 is a mid-sized barred spiral galaxy located in the constellation Cetus.
NGC 1022 is a barred spiral galaxy located approximately 68 million light years away in the equatorial constellation of Cetus. It was discovered on September 10, 1785 by William Herschel. NGC 1022 is a member of the Cetus-Aries group of galaxies.
NGC 470 is a spiral galaxy in the constellation Pisces. Located approximately 91 million lightyears from Earth, it was discovered by Friedrich Wilhelm Herschel in 1784. The galaxy also weakly interacts with NGC 474.
NGC 2090 is a spiral galaxy located approximately 40 million light-years from the Solar System in the Columba constellation. It was discovered on 29 October 1826 by Scottish astronomer James Dunlop. NGC 2090 was studied to refine the Hubble constant to an accuracy within ±10%.
NGC 3309 is a giant elliptical galaxy located about 200 million light-years away in the constellation Hydra. NGC 3309 was discovered by astronomer John Herschel on March 24, 1835. The galaxy forms a pair with NGC 3311 which lies about 72,000 ly (22 kpc) away. Both galaxies dominate the center of the Hydra Cluster.
NGC 679 is an elliptical or a lenticular galaxy located 210 million light-years away in the constellation Andromeda. The galaxy was discovered by astronomer William Herschel on September 13, 1784 and is a member of Abell 262.
NGC 710 is a spiral galaxy located 260 million light-years away in the constellation Andromeda. It was discovered by the Irish engineer and astronomer Bindon Blood Stoney on October 28, 1850 and is a member of the galaxy cluster Abell 262.
NGC 1400 is an elliptical galaxy in the constellation Eridanus. At a distance of 65 million light-years from Earth, it was discovered by John Herschel in 1786. It is a member of the NGC 1407 group, whose brightest member is NGC 1407. The NGC 1407 group is part of the Eridanus Cluster, a cluster of 200 galaxies.
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 535 is a lenticular galaxy in the constellation Cetus. It is estimated to be 222 million light years from the Milky Way and has a diameter of approximately 65,000 light years. The supernova SN 1988ad was observed near these coordinates. NGC 535 was discovered on October 31, 1864, by astronomer Heinrich Ludwig d'Arrest.
NGC 706 is a spiral galaxy located in the Pisces constellation about 230 million light years from the Milky Way. It was discovered by the German–British astronomer William Herschel in 1786.
NGC 5619 is an intermediate spiral galaxy in the constellation Virgo. The galaxy was found on April 10, 1828 by the British astronomer John Herschel. It is located about 390 million light-years away from the Sun.
NGC 538 is a barred spiral galaxy in the constellation of Cetus. It is located about 250 million light-years from the Milky Way with a diameter of approximately 95,000 ly. NGC 538 was discovered by the American astronomer Lewis Swift in 1886.
NGC 3412 is a barred lenticular galaxy located in the constellation Leo. It was discovered on April 8, 1784 by the astronomer William Herschel.
