The NEW Tele Vue 8mm Ethos Eyepiece
At NEAF 2008 Tele Vue 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!
| The 8mm Ethos is dual barrelled for 1.25" and 2" focusers and has 15mm Eye Relief |
The 100° compared to the plossl 50° field of view looking at the Andromeda galaxy. |
Ideal for Bino Vue use |
See faint stars become visible and more detail on all deep sky objects!
The large apparent field of view combined with the shorter focal length, will, for a given field in the sky, result in higher magnification, giving you a darker sky background, and this will enable you to see fainter stars and more detail!The 8mm Ethos delivers:
- 100° apparent filed (50% larger in area than the 82° Naglers)
- Comfortable eye relief so you can wear you spectacles!
- Accepts DIOPTRX for eyesight astigmatism correction
- Distortion Correction
- High contrast and on-axis sharpness for planetary viewing
