Tele Vue EN6-02.5 overview

  • 1Description

Based on the original Nagler design, the 7-element/4-group lens configuration employed in the Tele Vue Nagler Type-6 2.5mm Eyepiece was designed as an ideal eyepiece for lunar and planetary viewing.

Despite its short focal length, the optical properties allow it to maintain its wide 82° apparent field of view, and a comfortable 12mm eye relief that provides space between the lens and eye to prevent accidental contact that can interfere with views. Built to Tele Vue's exacting standards, the Type-6 features anti-reflection fully multi-coated optics to improve brightness, color rendition, and contrast; and a fold-down rubber eyecup that helps to block stray peripheral light from interfering with the views and to further enhance contrast. A textured collar around the body ensure safe handling in the cold or while wearing gloves. The Type-6 has a barrel diameter of 1.25" to fit into the most common sized focusers and accessories, and is parfocal with all Tele Vue group 'B' eyepieces, allowing you to change eyepieces within the group without having to refocus every time.

    Tele Vue EN6-02.5 reviews

    Nagler Type-6 2.5mm Eyepiece (1.25") is rated 3.5 out of 5 by 2.
    Rated 5 out of 5 by from excellent eyepiece! this is as good an eyepiece as you're going to get for high magnification, wide views and low weight. Of course, used in the wrong application or scope it may disappoint. However, DON'T, berate the quality of this eyepiece on those misguided criteria!

    Rated 2 out of 5 by from Too much power for an Orion XT8 Looking at the planets through an Orion XT8 this eyepiece is just too much power... even the 3.5mm version is pushing it. The net result is a dark and muddy image. Better to back off a bit to a lower power eyepiece. The eyepiece may work well for scopes of greater light collecting ability (or finer quality)... but definitely not an XT8.
