Hi Mark
What will your primary focus be? Planetary imaging or deep-space imaging?
For deep-space imaging, you're better off trying to find the f/4 8" - being a faster scope, exposure times will be less. The shorter tube will also help on the lighter mount. However you will need the Baader MPCC to correct for coma.
Also remember that any DSLR may not come to focus in your 8" newt without moving the mirror up the tube, or getting a very low profile focuser.
The HEQ5 probably will do what you want, but I'd recommend the EQ6 for added stability. In light winds, you don't want a 3-5 minute exposure ruined by shaking.
