Located in Monoceros Discovered by John Flamsteed about 1690.

The Rosetta Nebula is a vast cloud of dust and gas, extending over an area of more than 1 degree across, or about 5 times the area covered by the full moon. Its parts have been assigned different NGC numbers: 2237, 2238, 2239, and 2246. Within the nebula, open star cluster NGC 2244 is situated, consisted of the young stars which recently formed from the nebula's material, and the brightest of which make the nebula shine by exciting its atoms to emit radiation. Star formation is still in progress in this vast cloud of interstellar matter. Although various values for its distance occur in the literature, our adopted distance from the Sky Catalog 2000 implies a true diameter of the nebula of about 130 light years. Burnham quotes a mass estimation of 10,000 (Minkowski 1949) to 11,000 (Menon 1962) solar masses, so it is one of the more massive diffuse nebulae.

A very lovely image Trevor.

You got really close in to the nebula too.

Lots of Info. which is excellent.

Wow that is truly stunning. The diffraction spikes are very effective and beautiful detail in the nebula.

So nice to see the stars being the centre of attention. They look so much better than the bloated haloed things I end up with when concentrating on the nebulosity

I absolutely love this image, full of detail. I also enjoy reading the description and info as much as looking at the image. Have a virtual pat on the back from me...
