The Rosette Nebula, NGC2237-39, 46, Monoceros

An appropriately named nebula that surrounds NGC2244, a young star cluster of ~15 stars including the 6th magnitude star 12 Mon. It is rather difficult to make out much detail in small telescopes, but fairly easy by photography. Clearly evident is the cavity in the nebula created by the stellar winds of the hot, young stars. Visible, too, are numerous dark dusty regions and globules suggestive that star formation is on-going; distance 2,600 ly.
