Due to high demand and global product shortages due to the pandemic, please call for availability.

Experience the night sky with "Nagler-Vision". To borrow a quote from Tele Vue's website:

"With Naglers, my aim is to approach the wide angle perspective of naked eye vision, while maintaining the highest degree of sharpness, contrast, and viewing comfort. The goal is to allow the telescope to virtually 'disappear', leaving the impact of 'spacewalk' viewing. -Al Nagler"
Thank you Al.

These eyepieces are suitable for anyone, and any telescope. They are well-corrected to f/4. If you are a Dobsonian owner, then you'll appreciate not having to nudge your scope as often thanks to the wide field of view.

Tele Vue's legendary eyepieces are best-in-class, and truly exquisite. The attention to every detail, from producing the highest-quality optics to the fit and finish, and you'll know why you must have at least one in your collection. We bet you can't own just one.

One of the most expensive features of good optics is contrast, and the more, the better. The highly optimized anti-reflection coatings, precision-ground edge-blackened lenses, inner light-suppression threads and rubber eyecup deliver the goods.

Applying the experience of the Radian development to the 82° Nagler series, The Nagler Type 4 yields 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. Dioptrix compatible for those suffering astigmatism but wishing to not wear eyeglasses.

For deep sky viewing, the comfort, clarity and contrast gets us closer to our "spacewalk" viewing goal.
