Abell 61 (PNG077-6+14-7) is a planetary nebula in Cygnus. The central variable 17th magnitude star WD1917+461 is the blue star in the center of the nebula.Surrouning most of the nebula is a faint rim that becomes darker near the bottom left side. Research done by Tweedy and Kwitter indicate the darker portions of the rim may be due to interactins with Interstellar Medium.
