Re: ATM Compact Reflector Designing

[Ari <Ari@birmingham-us.crosswinds.net>]

The Schief has long focal ratios. My money's on the Yolo, or an
unobstructed Newtonian (with a toroidal secondary). I've been thinking
about these designs for a second scope, after I finish my first Newt.

Just saw something on a Herrig design:

2 spherical mirrors, at 8" he has an f/11.5 scope.


Hope this helps,
