Neumann Press, The 5mm Nagler Type 6 1.25" Eyepiece 82°

5 mm Nagler Eyepiece for Deep-Sky Observers

The Tele Vue 5 mm Nagler Type 6 provides an 82 degree apparent field of view in a 1.25 inch barrel. Its 7-element optical design uses exotic glass and advanced coatings to deliver high contrast and pinpoint sharpness across the full field. Every unit passes a 100 percent visual inspection on flat-field test instruments before it leaves the factory. This eyepiece suits astronomers who want immersive, high-power views of planetary and deep-sky objects.

Fits 1.25 Inch Focusers and Barlow Lenses

The 1.25 inch barrel slides directly into any standard focuser or diagonal accepting that diameter. No adapters are required for basic use, and the eyepiece works with common Barlow lenses to extend magnification options. Blackened lens edges and anti-reflection threads suppress internal scatter, preserving contrast even in light-polluted skies. Observers using 2 inch focusers will need a separate reducer to seat this eyepiece.

Steps Up from Narrower Field Eyepieces

Compared with typical Plössl or orthoscopic designs, the 82 degree field creates a spacewalk sensation that makes object location and tracking more intuitive. The upgrade is most noticeable at high power where narrower eyepieces feel like looking through a straw. Buyers who need longer eye relief or a 2 inch barrel for lower-power wide-field work should consider other models in the range.
