Jo….thanks, hadn't thought about the classic cass from gso, food for thought.
Jeff, thanks for your thoughts too. Should have said that this is visual only.
Quite a while ago I did have a 150mm f12 refractor which did get 1.5 degree TFOV with a 40 68 eyepiece, so not too concerned with a bit less from a Mak.
Decision time coming
