Product Highlights
  • 100° Apparent Field of View
  • 15mm Eye Relief

The Tele Vue 13mm Ethos Ultra Wide Angle Eyepiece is the first astronomical eyepiece with 100° apparent field of view. For a given magnification, it shows 50% more sky than the previous widest-field oculars. While sharpness is inherent to the optical design, contrast is maximized through the intelligent use of flat finished baffles and ultra low reflectance, high efficiency coatings tuned to the composition of each element.

The 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. It can fit both 1.25" and 2" type telescopes.

Accepts DIOPTRIX astigmatism correcting lenses. This allows those with astigmatic vision to enjoy the sharpest viewing experience they've ever had, without using their glasses.
Can be combined with Barlows and Powermates for higher magnifications, without being subject to vignetting.
Will accept 48mm filters by adding the optional EBX-2120 2" extension tube.
