Observation history

Arrest discovered NGC 503 using an 11" reflecting telescope in Copenhagen. His position matches perfectly with PGC 5086. At the time of discovery, he considered the possibility of having observed one of William Herschels discoveries (NGC 495, 496, 499). [6] John Louis Emil Dreyer, creator of the New General Catalogue, described the galaxy as "extremely faint, extremely small" with a "double star 4 arcmin to southwest". [5]

NGC 462 Elliptical galaxy in the constellation Pisces

NGC 462 is an elliptical galaxy located in the Pisces constellation. It was discovered by Albert Marth on 23 October 1864. Dreyer, creator of the New General Catalogue, originally described it as "extremely faint, very small, stellar". The word stellar clearly suggests an initial misidentification of NGC 462 as a star.

NGC 500 Lenticular galaxy in the constellation Pisces

NGC 500 is a type E-SO lenticular galaxy located in the Pisces constellation. It has an apparent size of .8 by .6 arcminutes and an apparent magnitude of 14.2. It was first discovered in 1850 by Bindon Blood Stoney during his time at Birr Castle in Ireland.

NGC 485 Spiral galaxy in the constellation Pisces

NGC 485, also commonly referred to as PGC 4921 or GC 270, is a spiral galaxy in the constellation Pisces. It is located approximately 86 million light-years from Earth and was discovered on January 8, 1828 by astronomer William Herschel. It was later also observed by Heinrich d'Arrest and Herman Schultz. When NGC 485 was originally categorized in the New General Catalogue by John Louis Eil Dreyer in 1888, it was incorrectly described as a "considerably faint, pretty large, round, 8th magnitude star 3 1/2 arcmin to southwest".

NGC 495 Barred spiral galaxy in the constellation Pisces

NGC 495, also occasionally referred to as PGC 5037, UGC 920 or GC 278, is a barred spiral galaxy in the constellation Pisces. It is located approximately 184 million light-years from the Solar System and was discovered on 12 September 1784 by astronomer William Herschel.

NGC 496 Spiral galaxy in the constellation Pisces

NGC 496, also occasionally referred to as PGC 5037, UGC 927 or GC 288, is a spiral galaxy in the constellation Pisces. It is located approximately 250 million light-years from the Solar System and was discovered on 12 September, 1784 by astronomer William Herschel.

NGC 499 Lenticular galaxy in the constellation Pisces

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 501 Elliptical galaxy in the constellation Pisces

NGC 501, also occasionally referred to as PGC 5082 or GC 284, is an elliptical galaxy in the constellation Pisces. It is located approximately 224 million light-years from the Solar System and was discovered on 28 October, 1856 by Irish astronomer R. J. Mitchell.

NGC 502 Lenticular galaxy in the constellation Pisces

NGC 502, also occasionally referred to as PGC 5034 or UGC 922, is a lenticular galaxy in the constellation Pisces. It is located approximately 113 million light-years from the Solar System and was discovered on 25 September 1862 by German astronomer Heinrich Louis d'Arrest. When the Morphological Catalogue of Galaxies was published between 1962 and 1974, the identifications of NGC 502 and NGC 505 were reversed. In reality, NGC 502 is equal to MGC +01-04-041 and not MCG +01-04-043 as noted in the catalogue.
