I must have too much time on my hands, I keep idly looking at hardware that my AP journey might bring in to my hands next. I am without a doubt up against some design compromises with my C925, which was bought as a purely visual scope and which I have been cajoling into service for AP.

I keep looking at the CF truss GSO RC scopes and thinking they do not look right to me and would have potential flexure issues. The theory behind a Serrurier truss being a central structural section where the scope is mounted (Dovetail for instance) and then the truss tubes supporting structures to mount the primary and secondary mirrors and other hardware.

Are the GSO truss tube scopes really not a Serrurier design, just a truss tube design with the primary assembly basically being reinforced by the truss? They won't have equal flexure on the primary and secondary mirror assemblies will they?
