Wax Eye

Big Brain Gets a Wax Eye
Now don't say "ewe" too quickly as this simple eye uses technology from optics (a single double convex lens) and a piece of waxed paper from a local grocery store. The wax paper is the image forming element and the lens projects the image onto the paper. A sensor or camera is placed behind the paper and photos the image in real time using macro mode. It works well on brighter objects, terrestrial, the Moon and brighter Planets, depending on the diameter of the lens.
