Good for you Frank. You'll have fun with your new toy.
What's important is your image scale:
206.265/600mm * 4.4um ~ 1.5 [ED80] [Atik]
206.265/600mm * 6.4um ~ 2.2 [ED80] [Canon]
On your ED80 at prime focus you see your image scale drops to 1.5 opposed to 2.2 with the canon. So you'll capture more fine details with your Atik.
Just start with short exposures then increase to figure out the full well capacity on your CCD. Your 10" RC will collect a lot of light in a 5min sub depending on the target. Try 1min first.
