NGC 2237, Rosette Nebula

Located an estimated 1,500 light-years from Earth in the constellation Monoceros, the Rosette Nebula is a spectacular region of ionized hydrogen excavated by the strong stellar winds from hot O- and B-type stars in the center of the young open cluster NGC 2244. It is a region of on-going star formation with an age of about three million years. This area is rich in hydrogen alpha wavelength emissions.

I cannot make up my mind which version I like the most. With green of without green. This is blue version.
