NGC2403 - Galaxy in Camelopardalis 

ngc2403 HaLRGB


Discovered by William Herschel in 1788.

This beautiful spiral galaxy is an outlying member of the M81 group of galaxies, and thus about 12 million light years distant.

NGC 2403 is among the more conspicuous Northern objects which Charles Messier missed when compiling his catalog. Thus its discovery was left to William Herschel.
