One more reason for me procrastinating on getting this mirror coated...
Do I want SiO or SiO2 (which looks like it is harder, but cost more) overcoat? Does it make that much difference? Do "enhanced" coatings make that much difference? (When combined with the coating on the secondary, I would think it was very important. Is it really?
