A quick comment perhaps not entirely relevant - carbon fibre is not an appropriate material for some scopes. For example refractors its a poor match and worse than aluminium alloy which closely matches the change in focus of an APO objective.

I am not sure about a Mak Cass, it does have a corrector plate.

Carbon fibre is certainly the go for mirrored scopes like RCs, CDks, Newts.
