NGC 3000

NGC 3000 is a double star located in the constellation Ursa Major.^[1] It was first discovered and observed by Bindon Stoney an assistant to William Parsons, on January 25, 1851,^[2] and was initially catalogued as a nebula-like object. Since its discovery, NGC 3000 has been observed and studied using various telescopes.

Discovery

Bindon Stoney first described NGC 3000 as a "very faint, small, irregularly round, mottled but not resolved" galaxy. However, its recorded position, precessed to RA 09 49 02.6, Dec +44 08 46, shows no object at that location. Analysis reveals Stoney's recorded positions for objects in this region consistently have a systematic error of approximately 2 arcminutes to the east-northeast. Applying this correction places the coordinates nearly precisely on a pair of stars now identified as NGC 3000.^[3]
