Auguste Voigt discovered NGC 4255 in 1865 with the 31-inch silver-on-glass Marseille reflector. C.H.F. Peters independently found it with the 13.5-inch refractor at Hamilton College Observatory (discovery date unknown) and listed it as a "nova" in his 1881 Copenicus article. Peters' position matches UGC 7348. As Voigt's discoveries weren't published, Peters is credited in the NGC.

400/500mm - 17.5" (3/24/90): fairly faint, fairly small, elongated WNW-ESE, small bright core, stellar nucleus.
