Tele Vue 3 to 6mm Nagler 1.25" Zoom Eyepiece
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 — however Tele Vue has set out to change this! The Tele Vue zoom is small, lightweight, and offers the same magnifications (with click-stop settings) as multiple eyepieces 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.
