I need a supplier of 1/2" M.A. mirrors at prices I can justify
- I'm almost finished building two new planetary scopes: one with a 4.25"
f-12 primary and a second one with a 3" f-9.
I have not been able to find a supplier of 1/2" M A mirrors at prices I
can justify. Edmond and Newport want $50 !!
I'm tempted to try an Amici prism but do not have enough experience to
justify that alterative. Anyone have any suggestions?
