Ok, I’ll prepare some stuff to discuss, others can also. Feel free.
FYI as of today my 12 inch mirror is now 1/6 th wave !! (Better than most industry commercial mirrors, not good enough for me)
This weekend will go to stellafane where they have an autocollimator. I am hoping with careful very short iterations get it better than 1/8 wave and be finished ( dare I dream of 1/10 wave??)
