I'm selling my trusty 5mm Radian. Its optics are in pristine condition, and the eyepiece comes with the original box, end caps, pupil guide (still in its factory plastic stapled to the paperwork in the photo below), and papers signed by Al. I thought it was in mint condition, but as I looked it over in the daylight I was surprised to find some fine set screw marks on the barrel. I always used it in a compression fitting on my scopes, but occasionally let fellow observers try it out, which accounts for the marks. (I've got a second small image of the scratches I can send if you're interested. I tried but couldn't manage to get both images to load with the ad.) I've been very happy with this eyepiece, and am only selling because I've just upgraded to a Nagler 3-6mm zoom.
Asking $190 plus shipping.
