Do lots of short exposures and combine them. I've seen some pretty amazing work done this way with the 10D. Darks and flats could also be created with the 10D for noise reduction.

And M27 is one of the brightest objects in the sky. It looks like the
longest exposure you can expect to take with a D10 is 2 to 4 minutes. For
really deep imaging, you need quite a bit longer.
