I'm trying to cut down on the size of my eyepiece collection by getting rid of eyepieces that won't work in both of my telescopes. The 5.2xl is the best planetary ep for my 6 inch Maksutov Cass.(unfortunatly seeing doesn't permit its use very often), but will not work in my 80mm refractor because it is just too big and tall. I'd like to trade for a 5mm Radian that I could use in both telescopes. My xl is in perfect shape - I got it last Christmas and have only had good enough seeing in the Maksutov to use it a couple of times. Optics, mechanics, cosmetics perfect, and I have the orignal green box and both caps. No plastic box as I found this useless and tossed it. Your Radian should be in as new optical and cosmetic shape, too - with pupil guide and box in nice shape. I dont mean to sound like a jerk, it is just that I bought a used eyepiece on the internet once and found little scratches on the eye lens as if the previous owner had wiped it with the end of his/her shirt, so I want to make sure I dont have to deal with this again. Thanks for your time, sorry for the long-winded description.
