Tele Vue 17mm Ethos Eyepiece

The Tele Vue 17 mm Ethos Eyepiece with a 2-inch barrel is part of the Tele Vue Ethos Eyepiece Series. These eyepieces have pushed the boundries of optical excellence and maximum field of view, creating an unrivaled eyepiece experience. An important benefit of the combination of large apparent field of view and shorter focal length is that for a given field in the sky, higher magnification results in a darker sky background. Fainter stars become visible and more detail is seen on all deep sky objects. The Tele Vue Ethos eyepiece provides another big magnification/contrast jump, yielding dramatic views simply not previously possible in any telescope. With the smaller exit pupil, eyesight limitations are also reduced. The Televue 17mm Ethos delivers a 100 degree apparent field (50% larger in area than 82 degree Naglers), comfortable eye-relief, accepts DIOPTRX eyesight astigmatism correctors, distortion correction, high contrast and on-axis sharpness for wide field planetary viewing. It is the 'do-it-all' eyepiece perfect for all scopes that can utilize this focal length.

The International Year of Astronomy (2009) celebrated the 400th anniversary of Galileo's first use of an astronomical telescope. Continue to celebrate by showing friends and neighbors the best of our wonderful universe. The Tele Vue philosophy (Ethos, if you will) has always been about inspiring 'spacewalk' vistas by creating the finest 'rich field' refractors and wide angle eyepieces. We hope the introduction of these new Ethos models will further rekindle the appreciation of astronomy and support all the worthy goals of IYA 2009. It's been quite a challenge to develop new Ethos eyepieces to the same performance standards achieved by the 13mm and 8mm models, perhaps the most honored in history. We hope the increased field of the 17mm and increased power of the 6mm will open up new visual experiences that Galileo could hardly have imagined, from small refractors to the largest Dobsonian telescopes.
