NGC 1553 is a prototypical lenticular galaxy in the constellation Dorado. It is the second brightest member of the Dorado Group of galaxies. British astronomer John Herschel discovered NGC 1553 on December 5, 1834 using an 18.7 inch reflector.
NGC 5566 is a barred spiral galaxy in the constellation Virgo, which is approximately 65 million light years away from Earth. The galaxy is the biggest in the constellation Virgo, stretching nearly 150,000 light years in diameter. The galaxy NGC 5566 was discovered on 30 April 1786 by the German-British astronomer William Herschel. It is included in Halton Arp's Atlas of Peculiar Galaxies. It is a member of the NGC 5566 Group of galaxies, itself one of the Virgo III Groups strung out to the east of the Virgo Supercluster of galaxies.
NGC 51 is a lenticular galaxy in the constellation Andromeda. It has a diameter of 90,000 light-years. The galaxy was discovered on September 7, 1885 by Lewis Swift, who described it as "Pretty faint, pretty small, round, brighter middle."
NGC 1169 is an intermediate barred spiral galaxy in the constellation of Perseus. NGC 1169 has a reddish center, indicating the region is dominated by older stars. In contrast, the outer ring contains larger blue-white stars, a sign of recent star formation. The entire galaxy is rotating at approximately 265 km/s.
NGC 267 is an open cluster in the Small Magellanic Cloud. It is located in the constellation Tucana. It was discovered on October 4, 1836 by John Herschel.
NGC 275 is a barred spiral galaxy located approximately 63 million light-years from the Solar System in the constellation Cetus. It is one of a pair of galaxies, the other being NGC 274. It was discovered on October 9, 1828, by John Herschel.
NGC 279 is a lenticular galaxy in the constellation Cetus. It was discovered on October 1, 1785 by William Herschel.
NGC 282 is an elliptical galaxy in the constellation Pisces. It was discovered on October 13, 1879 by Édouard Stephan.
NGC 283 is a spiral galaxy in the constellation Cetus. It was discovered on October 2, 1886 by Francis Leavenworth.
NGC 284 is an elliptical galaxy in the constellation Cetus. It was discovered on October 2, 1886, by Francis Leavenworth.
NGC 285 is a lenticular galaxy in the constellation Cetus. It was discovered on October 2, 1886 by Francis Leavenworth.
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 317 is a pair of interacting galaxies, consisting of a lenticular galaxy NGC 317A and a spiral galaxy NGC 317B, in the constellation Andromeda. It was discovered on October 1, 1885 by Lewis Swift.
NGC 324 is a lenticular galaxy located in the constellation Phoenix. It was discovered on October 23, 1835 by John Herschel. It was described by Dreyer as "questionable, faint, small, stellar".
NGC 332 is a compact and/or lenticular galaxy in the constellation Pisces. It was discovered on October 22, 1886 by Lewis Swift. It was described by Dreyer as "very faint, small, round, several stars near to south."
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 3631 is a spiral galaxy located in the constellation Ursa Major. It is located at a distance of about 35 million light years from Earth, which, given its apparent dimensions, means that NGC 3631 is about 60,000 light years across. It was discovered by William Herschel on April 14, 1789. It is a grand design spiral galaxy seen face on.
NGC 4731 is a barred spiral galaxy located near the Virgo supercluster. To its celestial south lies NGC 4731A, a small irregular galaxy. Both galaxies feature high concentrations of neutral HI gas. It is theorized that its elongated arm structure could be related to gravitational interactions with a nearby galaxy, NGC 4967. It is a member of the NGC 4697 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.
