Diane Lucas, an amazing individual, who used to share her 6" ATM Mak with some of us younger members. That was an exotic treat!
What else can you recall about that Mak? My club received a 4" ATM Mak recently. I understand there was a subculture of ATMers building Maks back then, as home-grown alternatives to costly refractors, and want to learn more.
It was called the Maksutov Club, which started at Stellafane back in the late 50's when John Gregory displayed his 5" Mak at Stellafane in 1956 and wrote his famous article about his Mak Cass design for Sky and Tel in 1957. The club published a newsletter from that time until the early 80's. The best of the articles became the two volume books "Advanced Telescope Making Technics-Optical"and the second volume "Mecanical" which are available from Willmann Bell. The Mak club also arranged for Hayward Glass in Cal. to make the Mak corrector blanks in sizes from 4" up to 11". Diane Lucas has a couple of articles in those books. Coulter Optics also sold the corrector shells in the 1970's as well.
