Sh2-71 is a planetary nebula in the constellation Aquila. Discovered in 1946 by Rudolph Minkowski this bright nebula is suggested to contain a close bipolar star in the center. The mag 13.8 center star is visible and is the nebulas exciting star but its companion star is unobservable. The interactions between the binary pair are ejecting matter away at high velocities in the range of 500km per sec and is believed to be the reason for the disrupted symmetry thereby producing an irregular disk shape with faint outer spherical structure.
