Also known as the Ghost Bush Cluster, NGC 6939 is a large, compact open cluster about 12 arcminutes across with a fairly even distribution of stars. As open clusters go, this one is pretty old, listed as being at least a billion years old. It is over 3800 light years away. The bright star to the lower right, HD 195085, is 7th magnitude. Flying Geese seems to have a somewhat triangular shape to it, maybe reminiscent of Canada Geese flying in a V-shape formation; can you see the direction the V is pointing in? This cluster is about 40 arcminutes south of the beautiful Fireworks Galaxy, NGC 6946.
