Chuck: I know for sure that I will never grind a lens or even a mirror for that matter. I simply have proven to many times in my life that Patience like that is not one of my virtues. I almost completed a 17" Dob once but sold if off before completion. Years of experience have proven that I am exceptionally skilled at writing checks and opening packages. NOT fabricating optics.

I'm thinkin 11" f/15 or longer would be nice. Perhaps the one in Orem will come available after I win the Lotto!
Steve, have you considered grinding and polishing your own large doublet? All the surfaces are spherical, so they are a snap to figure. Chasing down wedge is usually the only tedious part, and that can be avoided with care.
