Mike, How pleased are you with the Protostar diagonal? I've always thought that was a neat design & I'm really surprised that more 3 vanes aren't used. I have a 6" F9 Fagin mirror that's been up in my closet since 1985, which I paid $100.00 for. If I ever build a planetary scope, I plan to use a Protostar. Mr. Darian Rachal
