Hi Bob; I have already did everything you said in your email. The only thing I did not known was to increase the mirror diameter. What would be the correct size for mirror blank using a 24 inch diameter corrector plate? You are the first
person to tell me the design will work. Everyone else looks at me like I am crazy and wants to tell me why I am wasting my time. I use the Spread Sheet and said the glass use was BK7 glass 1/4 inch thick. Is there anyway to correct for the off axis astigmatism? Thank you again for writing back.Gordon Berry
