I have a very nice Pentax XL, 10.5mm in nearly perfect condition. The optics are perfect. The barrel has some rub marks from inserting it into the focuser. I have all the original packaging and end caps. $210 shipped.
I really hate to sell it, but I cannot use it in my binoviewer. My eyes are too close together. I had considered plastic surgery, but my wife thought that might be a tad on the stupid side.
If you've read the groups, you'll know that this is my favorite eyepiece out of all that I've owned. Now it can be yours, too.
Paypal is fine. Actually anything is fine. Sorry, no trades right now.
