What silly dill sold you that CCD?
Yeah, she's a great camera - ULTRA sensitive. Just watch out for blooms - it doesn't have ABG. MaxIM does a good pre-process job of removing them, Pixinsight less effective, and CCDStack average.
Keep those exposures coming. I wouldn't go much more than about 7 minutes per sub on M8, as I found at f/6.3 the blooms really started getting long on the bright stars.
