I have a similar scope (Celestron 9.25" SCT) and because of the focal ratio (F10) it's not much good for deep sky object photography without a focal reducer. Great for planets and precisely why I bought it.
I'm not saying your scope can't or won't do what you want, but there are many factors to consider if you want to head down the DSO astrophotography road.
Precise polar alignment of the scope/mount is the main hurdle.
Planet photography can be easily accomplished with a fairly cheap webcam ie: philips 840K toucam pro or the latest version: 900nc and a laptop for capturing on. Again, good polar alignment is a factor here too. I gather the scope is motorized..
But after saying all that you should be able to get some good moon shots by just hand holding your camera up to the eyepiece and firing away!
(focus is the hardest bit here)
Good luck with it all
