I have a TeleVue 3mm Radian for sale.
All coatings and elements are in excellent like new condition. Used about 6 times. Purchased by me directly from TeleVue.
The filter end of the barrel does have a dent in it. I did not use filters with this eyepiece so it did not bother me. You could try and straighten the barrel back out if needed.
Both end caps, original box/packaging/paper work and un-opened TeleVue Pupil Guide Disc included.
Asking $140 shipped tracked Priority Mail in the CONUS.
Thanks for looking!
