Description

Introduced at the 2007 Northeast Astronomy Forum (NEAF), Tele Vue once again broadened the amateur astronomer's perspective on the universe with: 100° of pure TeleVue quality. The field area of this eyepiece is more than 50% larger than the 82° field of the Nagler eyepiece design. The Tele Vue Ethos 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.

The 10mm Ethos is a member of the logical set of 17mm/10mm/6mm. It is par focal with the 13mm Ethos and it's 59mm rubber grip diameter makes this model usable in binocular viewers (for most people).

Miles G. ★★★★★

The 100-degree field of view is breathtaking—it feels like you’re floating in space. Even at f/5, the stars remain sharp right to the edge. A real game-changer for my observing sessions.

Ellie P. ★★★★★

I was worried the wide angle would be all distortion, but even at the edges stars stay pin-sharp across the whole 100° field. My observing sessions have gotten noticeably longer because I just don't want to take it out of the focuser.

Jason S. ★★★★★

That 100° field of view really does feel like you're looking through a window into space—my first night out with it was jaw-dropping. The sharpness across the entire field is incredible for such an ultra-wide eyepiece.
