I'm sure that all of the participants in this forum are familiar with the famous Maksutov-Cassigrain and Maksutov-Newtonian telescopes, but what about the "Maksutov-Gregorian" design? I recently came across such a telescope in a catelogue and had never heard of it before. Information on this design is next to non-existant on the internet. Does anyone know about this telescope design? How about a URL or FTP link to more information. Thanks!
