Forums; Members; Gallery; Events; Blogs Maksutov's 1944 design was the first-published meniscus telescope design, and was published in the widely-read Journal of the Optical Society of America. This led to professional and amateur designers almost immediately experimenting with variations, including Newtonian, Cassegrain, and wide-field camera designs. There are many Maksutov designs that use a Cassegrain configuration, mounti…
