IMHO @Cosmic Geoff is giving you good advice. C9.25 is long focal length suited to planetary / advanced DSO users with guiding and expensive well set up mounts. Obviously it's not impossible but unless you are very lucky with conditions etc you will soon get disheartened by images with long egg shaped stars.
Probably the closest to an all round scope would be the C8 but that is still hard to image with.
Have a look on the imaging section here and check the equipment used in profiles, you'll see lots of HEQ5, EQ6R and 70 to 80mm refractors.
For the price of the C9.25 alone you could get an HEQ5 / 80mm frac for imaging and a 8" synscan Dob for visual and still have money left over 🙂
You're doing the right thing by researching before buying though, wishing you all the best of luck and clear skies.
