These are unusual optical devices and can be used as widefield 4" eyepieces. Price is $200 plus shipping for all 3 eyepieces. The items are:

1. Leica 90mm
2. Leica 65mm
3. Canon 65mm

I think they were originally used in some X-ray application. They require a 4" focuser and a long F/ratio telescope as the focal lengths are quite long. I have only tried using them once so my experience with them are very limited.
