Nagler Type 4 82° Eyepiece | 22mm
Category: Eyepieces
Our Take
We highly recommend these if you wear eyeglasses while you observe. The top adjusts to put your eye the perfect distance from the eye lens so you can see the whole 82-degree field.
Description
Applying the experience of the Radian development to the 82° Nagler series, yielded more contrast, reduced pincushion, more true field, and longer eye-relief. 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.
