The Rosette Nebula - Wide Field
I used my unmodified Canon 40D and my 70-200 f/4 L IS zoom with a 1.4x extender to shoot the Rosette Nebula at 280mm and f/5.6, which produced a very wide star rich image. The background noise still ended up being a bit problematic but overall not a bad first try for this object, and always great to 'borrow' time on such a fantastically tracking mount!

Details about The Rosette Nebula From Wikipedia:
The Rosette Nebula (also known as Caldwell 49) is a large, circular H II region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. The open cluster NGC 2244 (Caldwell 50) is closely associated with the nebulosity, the stars of the cluster having been formed from the nebula's matter.
