Used Tele Vue 8mm Ethos Eyepiece - UT-12174 -SOLD-UT-12174: The Tele Vue 8mm Ethos eyepiece is essentially multiple eyepieces, delivering the true field size of a longer focal length, narrower apparent field eyepiece with the benefits of higher power and darker sky background.
Televue is known for its in-house eyepiece and telescope designs by Al Nagler. Televue's latest eyepiece brings new meaning to the term 'in-house.' The concept for the 8mm Ethos 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 (technical reference), and low pupil sensitivity for daytime use were specified criteria.
Following Tele Vue's philosophy of pushing the state of the art, long-time Televue employee and optical design protege 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.
The Televue 8mm Ethos eyepiece has now been shown at NEAF, TSP, RTMC, as well as other major astronomy events. The Televue Ethos has been extremely well received by the astronomy community and will be one of the most highly anticipated products to be released in years.
