De Vaucouleurs Atlas Description:
This low-luminosity irregular has a smooth image with little resolution into stars. There could be a faint nucleus. Karachentsev (2005) lists DDO 165 as a member of the M81 Group. Its distance is given as 4.6 Mpc and its absolute magnitude as MB = -15.1. The properties of the M81 Group are discussed by Karachentsev et al. (2002).
