Description: NGC 2336 is a beautiful barred spiral 10 degrees from the north celestial pole in Camelopardalis about 100 million light-years from us. It has many nice arm segments that seem to come from a ring-like structure around the end of the bar. The ring seems rather pink in my image, apparently due to many unresolved HII regions [Ref: WikiPedia]
