Tele Vue 8mm Ethos Eyepiece

Tele Vue 8mm Ethos Eyepiece

Tele Vue's Second 100 degree Field of View Eyepiece! Sky & Telescope Hot Product 2009.

At NEAF 2008 we were pleased to demonstrate a new 8mm focal length, 100° AFOV Ethos eyepiece. In addition to matching all the key performance criteria of its 13mm sibling, the new 8mm version is parfocal in 1¼" focusers with Radians, Plössls, Type 6 Naglers and 1¼" Panoptics. Further, its lighter weight and smaller diameter than the 13mm Ethos 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. In comparing it to our 8–24mm Zoom eyepiece, the 8mm Ethos has the power of the 8mm Zoom and 83% of the field of the 24mm setting!
