Re: [ATM] Cassegrain Secondary Magnification

Hi Alfredo,

Not sure if this helps:

http://www.telescopes.ru/articles/article5.phtml

The same author also later describes several more developed
designs for 8 inch scopes with F2.5 primaries and F ratios
between 7 and 10.  The design specifications are in ATM Journal
issue 2.  Shafer also describes similar designs using
sub-aperture Maksutov correctors in the old Telescope Making
magazine.  

Good Luck,

Rod Brackenridge.
