A pier is a possibility I'd considered, but a long focus Newt is a whole new scope. A major part of the attraction to me of the clasical Cass. design was that the only expense would be the new secondary & spider, my thinking was that it would be the cheaper option. However ...
The difficulty in procuring (and certainly in making) a convex hyperbolic secondary's moved me on to the simpler concave elliptical secondary of a Gregorian.
Perhaps it's the siren song of mirror grinding, I don't know.
In any case, I seem to have strayed off the topic of the Chinese Mak, just a bit. Apologies to anyone trying to follow threads.
Regards, Mike
