Our Take
We highly recommend the Type-4 Naglers 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.
