Discovered by William Herschel in 1798.

8.9-mag NGC 6946 was discovered by William Herschel on September 9, 1798.

NGC 6946 is a rather nearby spiral galaxy, which at one time was suspected to be an outlying member of the Local Group (Hubble 1936). It is highly obscured by interstellar matter of the Milky Way galaxy, as it is quite close to the galactic plane.

Nine supernovae have been detected in NGC 6946 as of this writing (March 2009):

With this number of supernovae which have been found in this galaxy, NGC 6946 is leading the statistics quite comfortably, currently with three SNe more than the follow-ups M83 and M61.

In the SAC 110 best NGC object list. In the RASC's Finest N.G.C. Objects Objects list. Caldwell 12 in Patrick Moore's list.
