Newtonians are great scopes, and with coma correctors are known to produce excellent bang for buck results.
One point of concern with Newts, are there size and dimensions have made some users call them like Wind Sails. Balance and Keeping the wind off will be key factors. As well as DIY'ing some Tube rings that will let you rotate the ota. Otherwise a newt on a eq mount places the focuser in very hard to get at positions.
An 8" F4 would be a sweet newt to go for and if you can afford it the R200SS is a good one to get, but the GSO 8" F4 is not very far behind. Coupled with a good coma corrector your will be set along with your DSLR to turn out some great imaging. The only other must is a ED80 as already stated this combo is perhaps the combo.
If you later decide to look at a C8, consider the used market here and overseas places like Amart. Late 80's and 90's C8's are well respected by many as the best to come out of Celestron.
