Tele Vue 3 - 6 mm Nagler 1.25" Zoom Eyepiece

There have been zoom eyepieces in the past, but none quite like the Tele Vue 3 mm-6 mm Nagler Zoom. Since the time of Galileo, short-focal-length (hence high-magnification) eyepieces have been notoriously difficult to look through. That has changed in recent years, especially with the introduction of Tele Vue's line of Radian eyepieces. The new Tele Vue zoom is small, lightweight, and offers the same magnifications (with click-stop settings) as four Radians while maintaining a constant focus and 50° apparent field. It also lets observers choose in-between focal lengths, thus giving them the ability to tune the magnification to atmospheric conditions, which is very critical for high-power viewing. Although the zoom's 10 mm eye relief isn't long enough for eyeglass wearers, it is enough to make this a very comfortable eyepiece to look through.

High contrast 3 mm - 6 mm planetary zoom eyepiece. Constant 50° field and 10 mm eye-relief. Click stops at 3, 4, 5, and 6 mm.
