Mark, Have you found out anything?? I just bought this and have the same problem. My boy accidentally disassembled the eyepiece, and the 2 separate glass pieces fell out. After re-assembling, the image is reveresed (reads right-to-left, instead of left-to-right). How are these 2 pieces supposed to be installed?
Also, for viewing slides, the top light gives a more colorful image than the bottom light on many images. Yet the instructions state to use the bottom light. Is there a reason for this?
