Hi Will
I am afraid I will have to agree with those who think that short focal length and inaccuracy of shape would defeat your idea. Some time ago there was a lot of talk about putting a plate of slow hardening resin like polyester resin
on a plate and rotating it on a disk turntable. The theory being that this would form a perfect parabola as the resin set and that this could then be
silvered to produce a workable astro mirror. Has anyone actually heard the results of this theory?
Cheers Peter
