I just found a 7" (1" thick) piece of glass that was marked "negative lense 3.5 ft 86mm EXP Telescope". It is concave on both sides. I bought it thinking it would be a neat desk item, but noticed that when I looked through it onto the 8" cassegrain mentioned above, the image was magnafied and very clear around the focal point of the cassegrain. Now I'm wondering if these two pieces could be combined to make something?
