Hi Dennis, is your model of scope computerised, I'm assuming that it is then the tracking it does would be enough for short exposures in Envisage (up to 30 seconds if you are in Alt/Az mode.
With a DSO like Orion you can take a series of short exposures say 50 to 100 at 2 to 4 seconds each and combine them in Autostar IP. The Drizzle feature is very handy as well for imaging.
The DSI II is a great camera for learning the art of CCD imaging with, I'm very happy with mine. The DSI manual explains some of the techniques and features but it is a typical Meade manual
Cheers
