Never went to x8 for DSO. Max I went was x5 but I'd say you could use x8 for planetary or other although it would depend greatly on the seeing. Here's a couple of pics:
90mm triplet native FL ~650mm barlowed x3 vs.
prime focus field.
FSQ native FL ~530mm barlowed x3 vs.
prime focus field.
The first pic I saw taken with an FFC blew me away. It was an Ha shot that Peter Ward took years ago in the keyhole area at a ridiculous FL 4m or 5m from memory with his RC and that sold it for me.
