NGC 504, also occasionally referred to as PGC 5084 or UGC 935, is a lenticular galaxy located approximately 189 million light-years from the Solar System [4] in the constellation Pisces. [2] It was discovered on 22 November 1827 by astronomer John Herschel. The object was listed twice in the General Catalogue, precursor of the New General Catalogue, as both GC 291 and GC 292. [5]

Observation history

Herschel discovered the object without recording a visual description. However, he noted the nebula "precedes NGC 507 by about 10 seconds and is half a field to the south of it". NGC 504 was later also independently discovered by Heinrich d'Arrest, using an 11" reflecting telescope in Copenhagen and assuming the object was new. This led to Herschel cataloguing the two observations separately as GC 291 and GC 292. [6] The objects were later combined by John Louis Emil Dreyer with the creation of the New General Catalogue, in which the galaxy was described as "very faint, small". [5]

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.
