NGC 1, also occasionally referred to as GC 1, UGC 57, PGC 564 or Holm 2a is an intermediate spiral galaxy of the morphological type Sbc, located approximately 210 to 215 million light-years from the Solar System in the constellation Pegasus. It was discovered on 30 September 1861 by Heinrich d'Arrest.
The Catalogue of Principal Galaxies (PGC) is an astronomical catalog published in 1989 that lists B1950 and J2000 equatorial coordinates and cross-identifications for 73,197 galaxies. It is based on the Lyon-Meudon Extragalactic Database (LEDA), which was originally started in 1983. 40,932 coordinates (56%) have standard deviations smaller than 10″. A total of 131,601 names from the 38 most common sources are listed. Available mean data for each object are given:
NGC 7522 is an astronomical object whose identity is in question. It was originally catalogued as a faint nebula. Although SIMBAD identifies it as PGC 70742, this is unlikely, due to the faintness of the galaxy. Instead, it is possible that a nearby star was accidentally catalogued as a nebula.
NGC 52 is an edge-on spiral galaxy in the constellation Pegasus. It was discovered on September 18, 1784, by William Herschel. He described it as "very faint, small, extended."
Abell 70 is a planetary nebula located 13,500-17,500 light years away in the constellation of Aquila. It is approaching the earth at 79 kilometers per second and expanding 38 kilometers per second. There is a galaxy named PMN J2033-0656 behind Abell 70, giving it a "diamond ring" effect.
NGC 67 is an elliptical galaxy located in the constellation Andromeda that was discovered on October 7, 1855, by R. J. Mitchell, who described it as "extremely faint, very small, round". The galaxy belongs to the NGC 68 group, which also contains the galaxies NGC 68, NGC 69, NGC 70, NGC 71, NGC 72, and possibly NGC 74.
NGC 131 is a spiral galaxy that was discovered on September 25, 1834, by John Herschel. This galaxy belongs in the NGC 134 group of galaxies: NGC 115, NGC 148, NGC 150, PGC 2000, IC 1555, and PGC 2044.
IC 5332, also known as PGC 71775 is an intermediate spiral galaxy about 30 million light-years away in the constellation Sculptor. IC 5332 is a delicate spiral galaxy that is unusually faint and beautifully symmetrical. As viewed from earth it is nearly face on. It has a very small central bulge and open spiral arms accounting for its classification (SABc). The galaxy lies in the direction of the galactic south pole.
NGC 331 is a barred spiral galaxy in the constellation Cetus. It was discovered in 1886 by Francis Leavenworth. It was described by Dreyer as "extremely faint, very small, round, a little brighter middle, 12th magnitude star 3 arcmin northeast." There are two candidates as to which object is NGC 331: PGC 2759 or PGC 3406, with the former being a much more likely candidate than the latter.
NGC 336 is a spiral galaxy in the constellation Cetus. It was discovered on October 31, 1885 by Francis Leavenworth. It was described by Dreyer as "very faint, small, round, suddenly brighter middle." It is also known as PGC 3470. Despite this, sometimes it is mistakenly identified as PGC 3526.
NGC 390 is a star located in the constellation Pisces. It was discovered on November 19, 1884 by Guillaume Bigourdan. It was described by Dreyer as very faint, very small, stellar." However, this position precesses to a position where there is nothing apart from a few scattered stars. Bigourdan's original measurements point exactly to a star, which is the most likely candidate for NGC 390; however, as a result of this confusion, a galaxy nearby has sometimes been mistaken as NGC 390.
ESO 198-13 is a ring galaxy with multiple ring-like structures located about 240 million light-years away in the constellation Eridanus.
NGC 486, also occasionally referred to as LEDA 1281966 or GC 275, is a spiral galaxy in the constellation Pisces. NGC 486 was discovered on December 6, 1850 by Irish engineer Bindon Blood Stoney.
NGC 503, also occasionally referred to as PGC 5086 or GC 5169, is an elliptical galaxy in the constellation Pisces. It is located approximately 265 million light-years from the Solar System and was discovered on 13 August 1863 by German astronomer Heinrich Louis d'Arrest.
NGC 511, also occasionally referred to as PGC 5103 or UGC 936, is an elliptical galaxy in the constellation Pisces. It is located approximately 499 million light-years from the Solar System and was discovered on 26 October 1876 by French astronomer Édouard Stephan.
NGC 525, also occasionally referred to as PGC 5232 or UGC 972, is a lenticular galaxy located approximately 95.6 million light-years from the Solar System in the constellation Pisces. It was discovered on 25 September 1862 by astronomer Heinrich d'Arrest.
NGC 527, also occasionally referred to as PGC 5128 or PGC 5141, is a lenticular galaxy located approximately 259 million light-years from the Solar System in the constellation Sculptor. It was discovered on 1 September 1834 by astronomer John Herschel.
NGC 3048 is a pair of spiral galaxies located in the constellation Leo. It was discovered on April 27, 1864, by German astronomer Albert Marth. The object consists of a visual pair of galaxies, PGC 1509261 and PGC 28595. PGC 1509261 is likely a physical pair with a much fainter galactic object not a part of the New General Catalogue, J095458+162726.
NGC 5523 is an unbarred spiral galaxy in the constellation of Boötes, registered in New General Catalogue (NGC). The galaxy forms an equilateral triangle with NGC 5641 and NGC 5466 when observed using a telescope from the ground.
NGC 4015 is a lenticular galaxy in the Coma Berenices. It is located between 215 and 220 million light years away. Its visual magnitude is 13.15.
