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 Dobsonians.

Tele Vue is known for its in-house eyepiece and telescope designs by Al Nagler; our latest eyepiece brings new meaning to the term “in-house.” The concept for this eyepiece was first proposed by Tele Vue President David Nagler, with performance parameters giving it the fundamental characteristics (the ethos) of a Tele Vue eyepiece: high contrast, comfortable eye relief and full field sharpness. Control of astigmatism, field curvature, lateral color, angular magnification distortion correction and low pupil sensitivity for daytime use were specified criteria.

Following Tele Vue’s philosophy of pushing the state of the art, long-time Tele Vue employee and optical design protégé Paul Dellechiaie took up the challenge and designed the basic eyepiece form. Under Al’s guidance, Paul tweaked his design to fulfill the original goals.

While sharpness is inherent to the optical design, contrast is maximized through the intelligent use of flat finished baffles and ultra low reflectance, high efficiency coatings tuned to the composition of each element.
