Haha, not at all Russell, you have read my mind. I have been looking very closely at that scope, in fact i had just mentioned it in a PM to Dunk. It is nice and fast. It will accept the TS 0.79 reducer corrector, dropping it from f5.9 to f4.6 @ 700mm fl. However, it might be too long for good wide field EAA use. And don't point it at anything too bright without a fringe killer on it.

Another possibility is the TS80 6-element Flat field APO at an amazing f4.4. It would seem ideal with great colour and a focal length of just under 400mm.
