22mm Nagler Type 4 Eyepiece

This 22mm Nagler Type 4 eyepiece fits 2-inch focusers and delivers an 82-degree apparent field of view. It is built for astronomers who want a single wide-field ocular for deep-sky scanning and large nebulae. The seven-element optical design uses advanced glass types to suppress ghosts and reduce pincushion distortion across the field.

Thermals noise power draw

As a passive optical component the eyepiece generates no heat, emits no noise and draws no electrical power during observing sessions. Its all-metal barrel and lens-cell construction simply reaches ambient temperature without active cooling. There are no fans, motors or electronic circuits to consider.

Click-stop eyeguard and optical gains

The click-stop adjustable eyeguard locks into position so eye relief stays repeatable at 19mm even when wearing glasses. Superior ghost suppression and reduced pincushion distortion come from the seven-element layout and advanced glass choices. These changes deliver higher contrast and a cleaner edge-to-edge image compared with earlier Nagler designs.

Questions about this item

How do I install the click-stop adjustable eyeguard and what is the common mistake?

Slide the eyeguard onto the eyepiece barrel until it clicks into one of the detented positions; the step users miss is confirming the click so the guard stays set during long sessions.

What maintenance will the 7-element lens and adjustable eyeguard need over time?

Clean the exposed lens surfaces with a soft brush and optical fluid when dust appears; the click-stop eyeguard mechanism requires no lubrication and has no user-serviceable parts.

What limit appears first during an all-night session with the 82° field and 19 mm eye relief?

The practical limit is eye fatigue from holding position at the wide 82° apparent field; the 19 mm eye relief stays comfortable for glasses wearers throughout.
