Tele-Vue's 1.25" diameter barrel Nagler Type-6 5mm Wide Angle Eyepiece is a wide-field telescope eyepiece designed for planetary and deep-space observations with a 7-element/4-group designed by optic legend Al Nagler. Its wide exit pupil and long 12mm eye relief makes this eyepiece ideal for comfortable viewing for extended periods. Contrast is enhanced by a fold-down rubber eyecup that prevents stray light from leaking into your eye, and a dimpled rubber collar helps to give it a slip-resistant grip in cold weather.
