If you're going to use it as an occasional imaging scope, and in alt-az, grab a field derotator.
Optec make a good one which will fit most scopes (there are others at Optec apart from the one I have linked to).
I also believe the CPC9.25 is Fastar compatible, so you can get a Hyperstar lens to attach to the scope.
Although, by the time you've bought all the stuff to image through it, you probably won't use it visually!!!!. So forget about the QHY8 attaching to the scope and if you want to do
occasional imaging through it, just use a webcam and take happy snaps of the Moon and the planets (however, a cam with long exposure enhanced innards will also work on many DSO's)
