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 4639 is a barred spiral galaxy located in the equatorial constellation of Virgo. It was discovered by German-born astronomer William Herschel on April 12, 1784. John L. E. Dreyer described it as "pretty bright, small, extended, mottled but not resolved, 12th magnitude star 1 arcmin to southeast". This is a relatively nearby galaxy, lying approximately 72 million light-years away from the Milky Way. It is a companion to NGC 4654, and the two appear to have interacted roughly 500 million years ago. NGC 4639 is a member of the Virgo Cluster.
NGC 5962 is a spiral galaxy in the equatorial constellation of Serpens Caput. It was discovered by the Anglo-German astronomer William Herschel on March 21, 1784. The NGC 5962 galaxy is located at a distance of 120 million light years and is receding with a heliocentric radial velocity of 1,957 km/s. It is the brightest member of the eponymously-named NGC 5962 group, which overlaps with the nearby NGC 5970 group; the two groups may be gravitationally bound.
NGC 10 is a spiral galaxy located in the southern constellation of Sculptor. It was discovered by John Herschel on 25 September 1834. The galaxy is located at a distance of 346 Mly from the Sun. Its morphological classification in the De Vaucouleurs system is SAB(rs)bc, where the 'SAB' denotes a weak-barred spiral, '(rs)' indicates a slight ring-like structure, and 'bc' means the spiral arms are moderately to loosely wound. Paturel et al. (2003) assigned this galaxy a classification of SBbc, indicating a barred spiral galaxy.
NGC 151 is a mid-sized barred spiral galaxy located in the constellation Cetus.
NGC 3021 is a spiral galaxy in the northern constellation of Leo Minor. It is about 93 million light-years away from Earth, and is receding with a heliocentric radial velocity of 1,537±4 km/s. This galaxy was discovered December 7, 1785 by Anglo-German astronomer William Herschel. The morphological classification of NGC 3021 is SA(rs)bc, which indicates a spiral galaxy with no central bar (SA), an incomplete inner ring structure (rs), and moderate to loosely wound spiral arms (bc).
NGC 214 is a spiral galaxy in the northern constellation of Andromeda, located at a distance of 194 megalight-years from the Milky Way. It was discovered on September 10, 1784 by William Herschel. The shape of this galaxy is given by its morphological classification of SABbc, which indicates a weak bar-like structure (SAB) at the core and moderate to loosely-wound spiral arms (bc).
NGC 266 is a massive barred spiral galaxy in the constellation Pisces. NGC 266 is located at a distance of 197 megalight-years from the Milky Way. It was discovered on September 12, 1784, by William Herschel. The form of this barred galaxy is described by its morphological classification of SB(rs)ab, which indicates a quasi-ring-like structure (rs) and moderate-to-tightly wound spiral arms (ab). It is the dominant member of a small group with six low-mass galaxies.
NGC 4424 is a spiral galaxy located in the equatorial constellation of Virgo. It was discovered February 27, 1865 by German astronomer Heinrich Louis d'Arrest. This galaxy is located at a distance of 13.5 million light years and is receding with a heliocentric radial velocity of 442 km/s. It has a morphological class of SB(s)a, which normally indicates a spiral galaxy with a barred structure (SB), no inner ring feature (s), and tightly-wound spiral arms (a). The galactic plane is inclined at an angle of 62° to the line of sight from the Earth. It is a likely member of the Virgo Cluster of galaxies.
NGC 5917 is a spiral galaxy located in the constellation of Libra. It was discovered by English astronomer John Herschel on 16 July 1835. This galaxy is located at a distance of 90.4 ± 6.2 million light-years (27.73 ± 1.90 Mpc) from the Milky Way, and is receding with a heliocentric radial velocity of 1,934.1 km/s. It is interacting with the neighboring galaxy, PGC 54817, at an angular separation of 4.2′. Tidal tails extend from PGC 54817 to the halo of NGC 5917.
NGC 570 is a barred spiral galaxy. It is located in the Cetus constellation about 250 million light-years from the Milky Way. It was discovered by the American astronomer George Mary Searle in 1867.
NGC 820 is a spiral galaxy located in the constellation Aries about 210 million light-years from the Milky Way. It was discovered by British astronomer John Herschel in 1828.
NGC 940 is a lenticular galaxy in the constellation Triangulum. It is estimated to be 222 million light-years from the Milky Way and has a diameter of approximately 80,000 ly. NGC 940 was discovered by Heinrich d'Arrest.
NGC 782 is a barred spiral galaxy located in the constellation Eridanus about 160 million light-years from the Milky Way. It was discovered by British astronomer John Herschel in 1834.
NGC 991 is an intermediate spiral galaxy the constellation Cetus. This galaxy was discovered by astronomer William Herschel in 1785.
NGC 938 is an elliptical galaxy located in the constellation Aries, approximately 184 million light years from the Milky Way. It was discovered by the Prussian astronomer Heinrich d'Arrest in 1863.
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 2803, also known as PCG 26181, is an elliptical or lenticular galaxy in the zodiac constellation Cancer. It was discovered March 21, 1784, by William Herschel. It is interacting with NGC 2802.
