NGC 2403 is an intermediate spiral galaxy in the constellation Camelopardalis. NGC 2403 is an outlying member of the M81 Group, and is approximately 10 million light-years distant.
It bears a striking similarity to M33, being about 50,000 light years in diameter and containing numerous star-forming H II regions. (from Wikipedia)

There are also many small and fuzzy galaxies and some faint Galactic Cirrus in the background!
