This item is out of stock but you can place an order now and we’ll ship when it becomes available.
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 8mm Ethos will be parfocal with Tele Vue's Plössls, Radians, Type 6 Naglers, Nagler Zooms, 1¼" Panoptics and 6mm ETHOS. Further, its light weight and small diameter makes the 8mm suitable for anyone using a binocular viewer. Another application is for spotting scope set-ups with the Tele Vue 60° 1¼" diagonal.
