The Rosette Nebula (NGC2237) in Monceros

Description:

The famous "Rosette Nebula" in Monoceros. Visible only as a faint, ghostly gray circle through even the largest telescopes, it reveals its brilliant colors with exposures of a few minutes or longer. It is located about halfway along a line from Procyon to the belt of Orion. Note the glittering open star cluster NGC2244 in the center of the nebula.

 The nebulosity consists of an enormous cloud of hydrogen gas that is being excited by the young hot blue-white stars in the interior cluster.
