What's "interesting" about this eyepiece is that it has new (2001) optics in a nearly mint condition, new-looking flat-top barrel that lived in the back of a Vernonscope cabinet for years. Unlike the Brandons with the current barrel style, this ep has enough eye relief to see the entire 50-ish degree field with glasses. It also gives sharp, contrasty images. I'm only selling it because I've switched scopes and no longer need this focal length.
Price is $130, including shipping in CONUS.
