Here <http://www.telescopes.ru/articles/article1.phtml> is a reasonably 
detailed description of a design by Klevtsov. The commercial implementation 
of this design is generally regarded as not very good, which might or might 
not say something about its intrinsic merits.

If Tom Krajci is still around he can probably point you to work Maksutov 
did decades ago. Certainly he anticipated most of the possibilities for the 
meniscus correctors that are named after him.
