All interesting ideas. But back to my original question - what is the minimum flatness in waves of light required for 20X80 binos? From all I have read, it is under 1 wave. But is it .25, .50, .75? And is there any affordable source (under $100) for a single unit of such mirror? Someone must know the answer, perhaps a formula, for the flatness question.
