Hello, I have a mirror that I have purchased to use in a scope that I am building. I am new to the ATM thing and the mirror will not work due to it's thickness and focal length.
Focal Length = I measured 76" someone else measured 80"
Focal Ratio = 6.3
Diameter = 12.5"
Thickness = 2 to 3 "
Coating = 90% Bereal
Mirror Material = Pyrex
This is all I know about the mirror. As I stated (and you can guess) I am a complete beginer. I have the packing already ready so All I am asking is $350 + Shipping and Insurance. Please feel free to email me if you are seriously wanting this. Thanks in advance and have a happy holiday season.
