Tele Vue 12mm Nagler Type 4 Eyepiece


Tele Vue 12mm Nagler Type 4 Eyepiece

Applying the experience of the Radian development to the 82 Nagler series, yielded more contrast, reduced pincushion, more true field, longer eye-relief, and fewer elements to achieve focal lengths of 12mm, 17mm and 22mm. With added eye-relief, the click-stop Instadjust eyeguard helps maintain proper eye distance and centration.
For deep sky viewing, the comfort, clarity and contrast gets us closer to our "spacewalk" viewing goal.
