9mm 82° Eyepiece for Telescopes
The Tele Vue Nagler Type-6 9mm eyepiece provides an ultra-wide 82 degree field of view through a 1.25 inch barrel. Its 7-element, 4-group optical design uses fully multi-coated lenses with blackened edges and anti-reflection threads to maximise contrast and sharpness across the entire field.
Suited for High-Power Planetary Views
Astronomers seeking a short focal length with generous eye relief will appreciate the 12mm eye relief that allows comfortable extended observing sessions. The parfocal design with Group B eyepieces simplifies swapping without major refocusing. Buyers needing a 2 inch barrel format or a different focal length for wider deep-sky framing should consider other models in the range.
Fold-Down Eyecup and Textured Grip
A fold-down rubber eyecup accommodates both eyeglass wearers and non-wearers for comfortable viewing. The slip-resistant textured surface on the barrel ensures secure handling during cold or damp nights. Every unit passes a 100 percent full-field visual inspection on flat-field test instruments before shipping.

Questions about this item
Which telescope focusers will accept the 1.25" barrel on this eyepiece?
Any focuser or diagonal with a standard 1.25" barrel opening will accept the eyepiece directly.
If I keep my other Group 'B' Tele Vue eyepieces, will I need to refocus when swapping to this 9mm?
The eyepiece is parfocal with Group 'B' models, so focus position stays nearly identical when you change between them.
How can I confirm the 82° apparent field is performing correctly after installation?
Point the telescope at a bright star field; stars should remain sharp to the very edge of the 82° circle without noticeable fall-off.
