Thanks Terry.
So I take it the VC is the better system. It sounds like a Tak BRC250 type style of scope.
A lot of scopes now are 2 mirrors and correctors. Its all the rage.
Planewave CDK, Orion Optics ODK, Ceravolo astrograph, Starizona Hyperion.
Perhaps Vixen and Tak were the first to mass produce that sort of system.
Greg.
