Tele Vue 8mm Ethos Telescope Eyepiece
Just when you thought their eyepieces couldn’t improve anymore, TeleVue introduces their Ethos eyepiece line with incredible 100-degree apparent fields of view! The combination of a great telescope and this 8mm Ethos eyepiece will enable views that are as near as can be to what astronauts must see looking out the window of their spaceship. As the view through this eyepiece is so expansive, the eyepiece itself vanishes from your vision, resulting in nothing except a dark, starry background with the object you want to see.
The apparent field of view of the 8 mm Ethos is 50% larger than the 82-degree Nagler!
All of the high-quality features you’ve come to expect from quality TeleVue eyepieces are here in the Ethos, including sharpness across the entire field, high contrast views, and superb control over aberrations such as astigmatism, field curvature, lateral color, angular magnification distortion, and low pupil sensitivity for daytime use. As with all Tele Vue eyepieces, you’ll enjoy a threaded eyepiece barrel, rubberized no-slip grip, rubber eyecup to cushion the view, 100% quality control, and a limited lifetime warranty.
