Tele Vue 19 mm Nagler Type 7 Eyepiece

We will begin taking orders once pricing has been confirmed.

As amateur astronomers world-wide know, the Tele Vue Nagler Eyepieces are legendary!  Their beautiful 82Âș apparent field of view with superb color correction, contrast and sharpness produce a "spacewalk" viewing experience like no other.  

The Nagler Type 7 series absolutely lives up to the experience we've come to expect from any Nagler eyepiece, but even more so, with 19 mm of eye relief that make them super comfortable for those who observe with their eyeglasses in place.  For those who do not wear glasses, a locking, adjustable eye-guard is included to help correctly position your eye to the eye lens at the proper distance.

The Tele Vue 19 mm Nagler Type 7 has a 2" barrel. It is parfocal with other Type 7's when eyepieces are in 2" mode and with 1.25" Tele Vue eyepieces (except the 40 mm Plossl) when used with the optional Hi-Hat 1.25" to 2" Adapter (ASF-8125).  

Here is what Tele Vue has to say about the Nagler Type 7 Series Eyepieces, anticipated to be available in early summer, 2025:

Concept
The Nagler Type 7 series was developed as a natural extension of our highly regarded, 85°, limited edition Apollo 11 eyepiece. However, the series can also be thought of as an extension of the long eye relief Nagler Type 4 concept. With the all-new Type 7 design layout, we achieved our goal of Apollo 11-like performance across a series of focal lengths that are eyeglass friendly.

Design Goals
The design goal was simple. The performance of each of the Type 7 focal lengths must equal or exceed that of the Apollo 11 eyepiece in the areas of full-field sharpness, contrast, distortion correction, eye relief, and pupil comfort, but across an 82° apparent field of view instead of 85°.

If you have been waiting for a Nagler series for eyeglass wearers, the Type 7 is it. Combining the expansive 82° apparent field of view with 19 mm of eyeglass friendly eye relief, and large eyelens, the Nagler Type 7s give a new dimension to the “spacewalk” viewing effect. An easily adjustable, locking eye-guard is included for those who don’t wear eyeglasses. It helps to correctly position your eye to the exit pupil so you don’t get too close to the eyelens, as well as blocks contrast-robbing stray light from interfering with the view. Speaking of which, of course we’ve applied all the optical coating and baffling features Tele Vue eyepieces are known for to maximize contrast and compliment the fully corrected field; revealing beautifully natural star colors with pinpoint sharpness. 

The optical layout affords unrivalled parfocality throughout the four focal lengths and even between 11⁄4” and 2” modes when used with the Tele Vue Hi-Hat 1-1⁄4” to 2” adapter (ASF- 8125). The Type 7 series is also parfocal with all other 1-1⁄4” Tele Vue eyepieces (except 40 mm Plössl) when those eyepieces are used in the Tele Vue Hi-Hat 1-1⁄4” to 2” adapter (ASF-8125). Available in focal lengths of 5.5, 9, 14, and 19 mm, the Type 7s compliment the 22 mm Type 4 and 31 mm Type 5 as eyeglass friendly Nagler's.
