I've been wanting to image this nebula since before I started doing Astrophotography and it all came together for me this weekend at the Alvord Desert in Oregon. Dark skies, cold temps, awesome company and good running equipment finally lined up! I've spent the last month watching tutorials, taking classes and practicing every night on my image acquisition and post processing techniques which came together well in what is probably my favorite Astro image so far.
The Rosette Nebula is a large spherical H II region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. The open cluster NGC 2244 is closely associated with the nebulosity, the stars of the cluster having been formed from the nebula's matter. The cluster and nebula lie at a distance of some 5,000 light-years from Earth) and measure roughly 130 light years in diameter. The radiation from the young stars excites the atoms in the nebula, causing them to emit radiation themselves producing the emission nebula we see. The mass of the nebula is estimated to be around 10,000 solar masses.
