Thats all good to know.
Yes indeed collimation and I are old friends. I learned on our f3.9, 4.5" Orion short tube reflector. The primary was not hard but my stubby fingers and the secondary had a fight or two.
I looked into premium mirrors but a gentleman by the name of Royce didn't think it would make much difference, at least for the primary but it was suggested a premium secondary could make a difference.
Certainly the flocking and the light shroud really help.
