Televue - 8mm Ethos Eyepiece


At NEAF 2008 Televue demonstrated 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 1.25" focusers with Radians, Plossls, Type 6 Naglers and 1.25" 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° 1.25" 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!

  • Apparent field: 100°
  • Focal length: 8mm
  • Effective field stop diameter: 13.9mm
  • Eye relief: 15mm (accepts DIOPTRX eyesight astigmatism corrector)
  • Barrel size: 2"/1.25"
  • Black barrel diameter: 53.4mm
  • Weight: 0.95 lbs (15.2 oz.)
