For planets you need aperture (like 8") and for DSO you need short focal ratio and usually short focal length. SCT 8" is very good for planets, and in some excent for DSO imaging (even with 6.4 reducer/corrector it will have quite long focal length). 8" Newtonian may be quite hard to use even on HEQ5.

You may choose HEQ5 + C8/TAL200K + OAG setup and you are ready to go on globular clusters, small nebulas and galaxies.

I have the 150P on a HEQ-5 PRO and it's great for DSO astrophotography :-)

For DSO astrophotography, an 80ED on a HEQ5 is a very good starting point. Speed is very important - the Equinox 80 offers a faster focal ratio than the 80 DS Pro.
