TeleVue Ethos

Tele Vue Optics

The Tele Vue philosophy (Ethos, if you will) has always been about inspiring "spacewalk" vistas. Now we bring you the world's first fully-corrected 100 degree astronomical eyepiece.

The Amazing TeleVue Ethos Eyepieces

Our first encounter with the original 13mm Ethos eyepiece was at the 2007 Northeast Astronomy Forum. Al Nagler called us over to have a look at something new, just before the doors were opened to the public. There in the focuser of an NP-101 we found an eyepiece with familiar Tele Vue green lettering yet a very unfamiliar shape. One way to describe it would be to say that someone had taken a familiar 12mm Nagler and stretched it lengthwise. Stepping up to the eyepiece, we were introduced an incredible 100º apparent field. The target images provided by Tele Vue showed the image to be tack sharp across the entire field of view, even in the fast f/5.4 NP-101 refractor. The Tele Vue Ethos performs the function of 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. Later that year, Tele Vue toured the country demonstrating the Ethos eyepiece at regional star parties. Customer feedback from this field testing was nothing short of incredible. The general consensus of customers who have actually observed with this eyepiece is "how soon can you get me one?" Clearly TeleVue has raised the bar once again with the introduction of the new Ethos eyepiece.
