Rosette Nebula

The Rosette Nebula is an emission nebula that lies about 5000 light years away in the constellation Monoceros. At the centre of the nebula lies the star cluster NGC 2244 which comprises massive O and B type stars that drive the stellar winds that have all but cleared the central region of gas and dust. These stars also provide the energy that excites the ring shaped emission cloud known as the Rosette Nebula.

    Great picture of the Rosette. I have been looking for such a pic of Rosette for illustration in an article I am writing for the Cedar Rapids amateur astronomy club newsletter and would like to use this. Of course, with acknowlegment to you and annotation of the image. Would that be possible?

    Amazing photo... you are a very remarkable astrophotographer.
