R.J. Mitchell resolved the double system NGC 2474/2475 on 9 Jan 1856 using Lord Rosse's 72". He recorded "may be a double neb. I see no star between (as suspected by [JH], but the two almost touch." JH appears to have resolved the fainter southwest component, but thought it was a star: "vS star sp." Dreyer assigned the discovery of NGC 2475 to LdR, but NGC 2474 is clearly the fainter component seen by Mitchell.

300/350mm - 13.1" (12/7/85): brightest of double galaxy, moderately bright, small, round. A mag 9 star is 3' NE.

400/500mm - 17.5" (1/19/91): brighter of a double system with NGC 2474 just 21" SW between centers. Moderately bright, small, round, very small bright core. Forms a striking pair with NGC 2474. Located 2.3' SW of mag 8.8 SAO 26594.
