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.

In 1¼" mode, if you use Tele Vue's "high-hat" 2"-1¼" adapter, the 6mm Ethos will be parfocal with Tele Vue's Plössls, Radians, Type 6 Naglers, Nagler Zooms, 1¼" Panoptics and 8mm ETHOS.

Lucy Z. ★★★★★

Finally got a clear night to test the 100° field, and the edge-to-edge sharpness on my Dob is genuinely impressive. The eyepiece feels solid and well-weighted, nothing flimsy about the build. Honestly, this thing has ruined me for narrower fields — I keep wanting to go back to it.

Jacob ★★★★★

Got these to pair with my 12-inch dob, and the edge-to-edge sharpness really impressed me during last night's lunar session. The eye relief is tight for glasses wearers, but the view itself is worth the slight squint.

Chloe ★★★★☆

The 100-degree field of view is genuinely immersive, though it took me a couple of sessions to get used to the sheer width. Eye placement is a bit finicky at first, but once you lock in, the view stays sharp right to the edge.
