More adventures with the DSLR.... Here is M33. I did this image of M33 with 10 x 10 minute subs (at f/6.2). I seem to have a fair amount of noise for this long of an exposure when I think I expected a little less. A full size image and exposure / processing details are at:

Camera - Canon 350D (Baader ACF modified)
C8 203 mm at f/6.2
G11/Gemini
Guiding - Megrez II at 1350 mm FL, DSI Pro, PHD guiding
An interesting comparison to an earlier CCD image is here (although I have to say that back in 2005, I may have brought less processing experience to the CCD image):
