Detailed Information:
NGC 6946 is a mixed spiral galaxy the has been the site of several supernovas. It was discovered by William Herschel in 1798. This galaxy is a member of the Coma-Sculptor Cloud like IC 342 and NGC 2403. It is located only 11 degrees off the plane of the Milky Way so it is obscured by gas and dust. While we see it as Mag 8.8., if this dust were removed it would be mag 7.2. It is quite near the open cluster, NCC 6939 and forms a nice pair in wide field views. This panorama can be seen below.
