Re: [ATM] Difficulty Level of figuring 3/4 Plate Glass



Sounds like it is time to make a 15" binocular telescope!
I cut a 14" piece out from a similar piece of glass and the guy
ground and polished it to a F4.5 mirror and that works well.  You
do have to start using thin mirror techniques to insure that you
don't get any astigmatism into the mirrors.

Replace the obvious words with the proper character.
