Tele Vue always aims to deliver stellar eyepieces that provide high contrast, comfortable eye relief, and full field sharpness. With the Ethos 100° & 110° Apparent Field Eyepieces, Tele Vue delivers yet again. Working closely together, Tele Vue's President, Al Nagler, and optical design protégé, Paul Dellechiaie, aimed to create an eyepiece that had control of astigmatism, field curvature, lateral color, angular magnification distortion correction, and low pupil sensitivity. While Dellechiaie developed the basic Ethos eyepiece design, under the close guidance of Nagler and the previous criteria in mind, the Tele Vue Ethos eyepieces were born.

With the use of flat finished baffles and ultra low reflectance from high-efficiency coatings tuned to the composition of each element of the Ethos eyepiece, the contrast is maximized and offers amateur astronomers ideal and Tele Vue quality views. Also, these innovative Ethos eyepieces are over 50% larger than the 82° field, broadening a viewer's perspective. And the Tele Vue Ethos eyepieces get better! The optical design allows these Tele Vue eyepieces to deliver the true field size of a longer focal length, narrower apparent field eyepiece while still reaping the benefits of higher power and a darker sky background.

The Tele Vue Ethos Eyepieces come in eight different sizes: 21mm, 17mm, 13mm, 10mm, 8mm, 6mm, 4.7mm, 3.7mm. Here at High Point, we are happy to offer each of the sizes so that everyone can enjoy the incredible eyepieces that Tele Vue has designed, whether they are looking for low, medium, or high magnification power.
