NGC 2403

NGC 2403 


NGC 2403 (also Caldwell 7) is an intermediate spiral galaxy in the constellation Camelopardis. It is an outlying member of the M81 group and is approximately 8 million light-years distant. (wiki)
This intersting and nice galaxy is rather large (23.4' x 11.8') but it's surface brightness is low (14.4m). It also shows some similarity with M33. Suprisingly, not very popular object among amateur astrophotographers..
