Good stuff Russ. Can you send along some images of your "parallelogram arm with my binos attached to it"? I once paid an eyewear lab to grind my prescription of lens down to a size that would fit into a camera eyecup. They sold me the glass lens and did the grinding for 10 bucks! That was back in the 70's.
