NGC 2237, the Rosette Nebula, is a huge but faint emission nebula in Monoceros.  Its 60 to 80 arc-minute apparent diameter is more than twice the full moon's (30 arc-minutes).  My photo is relatively useless; the scale of this object is way too large for the CCD and telescope combination I used.  I'll need to reshoot it later.
The Rosette is a starbirth region with a mass of about 10,000 suns.  Inside the Rosette Nebula is open star cluster NGC 2244, the young stars which power the nebula's emission.
