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!

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.

This was shot with a FF body and my new 70-300 f/4-5.6 L IS zoom lens. I hope to come back with more time, a camera that is H-alpha sensitive, and an optic with more magnification soon as this is a great object! I will add all the details on numbers of frames etc. soon...
