## Observation history

Although John Dreyer, creator of the New General Catalogue, credits the discovery to astronomer William Parsons, 3rd Earl of Rosse, he notes that many of his claimed discoveries were made by one of his assistants. In the case of NGC 501, the discovery was made by R. J. Mitchell, who discovered it using Lord Rosse's 72" reflecting telescope at Birr Castle in County Offaly, Ireland. The object was described "very faint, small (E in Birr diagram)" in the New General Catalogue.
