It depends a lot of what sort of astrophotography you want to do and what equipment you are going to hang off it.
I previously owned a CG-5 with a C8 on it. Perfectly OK with that scope on it for lunar and planetary work, maybe even for deepsky objects with an off axis guider, but IMHO it would struggle with a C8 and a guide scope. With an ED80, say, and a guide scope, it should be OK.
