Description

NGC 2403 (also known as Caldwell 7, https://en.wikipedia.org/wiki/NGC_2403) is an intermediate spiral galaxy in the constellation Camelopardalis. It is an outlying member of the M81 Group, and is approximately 8 million light-years distant. It bears a similarity to M33, being about 50,000 light years in diameter and containing numerous star-forming H II regions. The northern spiral arm connects it to the star forming region NGC 2404. NGC 2403 can be observed using 10×50 binoculars. NGC 2404 is 2000 light-years in diameter, making it one of the largest known H II regions, even larger than Tarantula Nebula in Large Magellanic Cloud. This H II region represents striking similarity with NGC 604 in M33, both in size and location in galaxy.
