An F.1 Reflector?? I have a 14" spherical F.1 polished blank. Looks like a meniscus lens for a mak. or something like that. I was wondering if there was a way to make something like this work as an imaging system?

Hello:
If it is for a 14" Maksutov, then I'd find out what kind of Maksutov it belongs in (i.e. Newtonian or Cassegrain, and what focal length primary mirror, etc), then build it. You could end up with a very nice scope. As far as using it as a primary mirror, that would be very difficult. To use as visually or for photography, you'd most likely need a schmidt corrector, which for a f/1 primary is quite hard to make. To use it without such a corrector lens would require refiguring the optic to an asphere, which at f/1 is again quite hard to do. Which ever way you slice it., fast optics are hard to deal with.
