Hi all

I've got my $5000 ready to spend on an astro-photography rig. I'm thinking either a skywatcher pro 100/120 or a celestron advanced 9.25/11. What would the merits of each be? I already have a 10" dob so would the larger celestron make the dob redundant? Would the HEQ5 that I can get with the skywatcher be good enough for observational use with the dob on top? Does anyone have any alternate suggestions? Bear in mind that I dont absolutely HAVE to spend all 5K at once. Also I already have a Celestron Neximage (although I had to dual boot my laptop to run the thing. Bloody Vista) and I have a Canon 400D coming soon.

Sorry for the barrage of questions, I just dont want to waste my money. Thanks for any advice in advance.
