Ahh a little clearer...then you are reasonably experienced in collimation and mount alignment, as well as the basics of astronomy.
An 8" ~ F4 reflector on a mount for astrophotography has more demands (re: finicky) than a refractor...wrt to collimation; tube flex; the camera gets in positions that is difficult and causes flex...etc. A refractor ~ 80~100mm will be easier.
But...the reflector is cheaper and gives a damn nice FOV, unless of course the refractor is a short FL (probably F6 at best).
A refractor is easier to start with in general but the reflector is probably a better tool.
As for cameras...just use a DSLR (Canon or Nikon) and control software like
BackYard EOS or
APT or
Sequence generator Pro (for Canon) or
BackYard Nikon (for the Nikon) to control the camera.
Mounts...depends upon your scope. Buy the best mount you can for the scope size. Bigger scopes need bigger mounts but probably 2/3 of the money spent should be on the mount.
An ED80 on a HEQ5 is a good start! Or maybe a short 8" F4 reflector on an EQ6!
Anyway FWIW.
