TeleVue Ethos

Tele Vue Optics

The TeleVue philosophy, or “ethos,” if you will, has always been about inspiring "spacewalk" vistas. Now, the brand has brought us the world's first fully-corrected 100-degree astronomical eyepiece. The consensus of customers who have observed with the Ethos eyepiece prior to their commercial launch was, "How soon can you get me one?"

The Amazing TeleVue Ethos Eyepieces

TeleVue has always pushed optical designs to new heights, and Ethos is no exception. Originally introduced in 2007, the Ethos eyepiece line set a new standard for eyepiece characteristics, expanding the apparent field of view to an incredible 100-degree field, creating an immersive viewing experience. The design concept was originally proposed by TeleVue President David Nagler, but was fully realized by optical designer Paul Dellechiaie, who went on to develop the equally incredible Delos and Delite eyepiece series.

The Ethos eyepieces are renowned for a reason: they’ve essentially set the standard that all professional and amateur astronomers now use to judge eyepieces. Featuring a wide field of view, incredible contrast and sharpness and a comfortable eye relief, the TeleVue Ethos has everything astronomers want in an eyepiece. The design is also optimized to control visual distortions and minimize aberrations in the produced image. The Ethos line of eyepieces accomplishes all this through a unique design that maximizes light retention and minimizes reflectance on non-reflective surfaces, resulting in a highly efficient instrument.

The Ethos line of eyepieces comes with a variety of focal lengths, including: Ethos 3.7mm, Ethos 4.7mm, Ethos 6mm, Ethos 8mm, Ethos 10mm, Ethos 13mm, Ethos 17mm and Televue Ethos 21mm.
