Galaxy and Cluster, NGC 6946 and NGC 6939

An interesting view, here a nearby spiral galaxy, NGC 6946, highly obscured by interstellar matter of our own galaxy is contrasted in this photograph by a distant open cluster, NGC 6939, in the same field of view.

Since 1917, eight supernovae have been observed in NGC 6946.
