Can you spot my one OOPS! in the adapter design? You should see it here. When I added the base, I put it on the wrong side of the adapter, so the lens top is "down" when installed. Actually it's better that way since when the scope is in use I can still see the focus marks. However, if I ever reprint it, I'll change it to put the top of the lens to the side.
