[APML] OT: Best place to get large optics?

[Alan Voetsch <critter12952@yahoo.com>]

Hi all,

Sorry for the off-topic. My wife wants to build another large truss
tube (she just finished a 12.5"). What she would like to know is where
is the best place to look for pyrex mirror blanks on the order of 20".
Or is there someone who will pre-set the focal length so all she'll
need to do is polishing and coating. Any information will be greatly
appreciated and feel free to reply to me off-list so as not to detract
from on-topic posts.

Thanks, Alan
