Images from the following two scopes (piggybacked) contributed to this image:
AG12+ASI1600MM at .70 asec/pix
TV127is+ASI183MM at .75 asec/pix.
They were all registered to the best R image taken on the AG12.
Using L from the TV NP127is refractor effectively eliminates the spikes from the AG12.

NGC1961 is about the same size as the Milky Way. It is an unusual spiral galaxy in that it is quite distorted. It is accompanied by many lovely small galaxies.

NGC 1961 (also known as IC 2133) is a spiral galaxy in constellation Camelopardalis. It is at a distance of circa 200 million light years from Earth, which, given its apparent dimensions, means that NGC 1961 is more than 220,000 light years across. The galaxy has been distorted, however no companion has been detected nor double nuclei that could show a recent merger. Its outer arms are highly irregular. Two long straight arms extent from the north side of the galaxy.[2] A luminous X-ray corona has been detected around the galaxy.[3][4] NGC 1961 is the central member of the small group of nine galaxies, the NGC 1961 group.[2]

It was discovered by William Herschel on December 3, 1788. Three supernovae have been observed in NGC 1961, SN 1998eb, SN 2001is, and SN 2013cc.
