ETA early summer 2025.
The all-new Tele Vue Nagler Type 7 series was developed as a natural extension of Tele Vue’s highly regarded, limited-edition Apollo 11 eyepiece.
With an all-new design, the Type 7 series achieves Apollo 11-like performance across a series of focal lengths.
They can also be considered an extension of the long eye-relief Nagler Type 4 series.
Eyeglass-friendly
If you have been waiting for a Nagler series for eyeglass wearers, the Type 7 is it. With an expansive 82° apparent field of view, 19 mm eye-relief, and a large eye-lens, the Nagler Type 7 eyepieces deliver Tele Vue’s renowned “spacewalk” viewing experience.
An easily adjustable, locking eye-guard is included for those who don’t wear eyeglasses. It helps you correctly position your eye to the exit pupil and prevents contrast-robbing stray light from interfering with the view.
Design Goals
The design goal was simple: The performance of each of the Type 7 focal lengths must equal or exceed that of the highly regarded Apollo 11 eyepiece in full-field sharpness, contrast, distortion correction, eye relief, and pupil comfort, but across an 82° apparent field of view instead of 85°.
Tele Vue has applied its expertise in optical coatings and light baffling to achieve maximum brightness and contrast across the fully corrected field. Stars are pinpoint sharp with natural colours.
The optical layout affords unrivalled parfocality throughout the four focal lengths and even between 1¼” and 2” modes when used with the Tele Vue Hi-Hat 1¼” to 2” adapter (ASF-8125).
The Type 7 series is also parfocal with all other 1¼” Tele Vue eyepieces (except 40 mm Plössl) when those eyepieces are used in the Tele Vue Hi-Hat 1¼” to 2” adapter (ASF-8125).
Available in focal lengths of 5.5, 9, 14, and 19 mm, the Type 7s complement the 22 mm Type 4 and 31 mm Type 5 as eyeglass-friendly Naglers.
