I set up my telescope outside of Powell Observatory last night and found an eyepiece eye relief cup on the ground. Someone lost it. I have attached a picture of it. Other than a little added dust it is still in good shape. Good enough to reinstall on the original eyepiece. My guess is that it is from either a large variable eyepiece or a 2" eyepiece.

I placed it in the observatory on top of the name badge container. Let me know if it is yours and I will help you retrieve it, if necessary.
