13mm Ultra-Wide Eyepiece for Deep-Sky Observers

The Tele Vue 13mm Nagler Type 6 provides an 82-degree apparent field of view through a compact 1.25-inch barrel. Its 7-element optical design uses exotic glass materials and advanced coatings to deliver pinpoint sharpness across the entire field with enhanced contrast. This eyepiece suits astronomers who want immersive, wide-angle views of nebulae and star clusters.

Practical Limits of the 1.25-Inch Barrel Standard

The 1.25-inch barrel diameter restricts the maximum field stop size, which caps the true field of view achievable at this focal length. Observers seeking wider true fields at low magnification will find the format limiting compared to larger barrel standards. The fixed 13mm focal length also offers a single magnification step per telescope.
