Tele Vue 8.0 Ethos Eyepiece
The Tele Vue Ethos eyepieces have pushed the boundaries of optical excellence and maximum field of view, creating an unrivaled eyepiece experience. An important benefit of the combination of large apparent field of view and shorter focal length is that for a given field in the sky, higher magnification results in a darker sky background. Fainter stars become visible and more detail is seen on all deep sky objects. The Tele Vue Ethos eyepiece provides another big magnification/contrast jump, yielding dramatic views simply not previously possible in any telescope. With the smaller exit pupil, eyesight limitations are also reduced. The Televue 8 mm Ethos delivers: 100¨degree apparent field (50% larger in area than 82 DN (degreeNaglers), comfortable eye-relief, accepts DIOPTRX eyesight astigmatism correctors, distortion correction, high contrast and on-axis sharpness for planetary viewing. It is the 'do-it-all' eyepiece perfect for all scopes that can utilize this focal length.

Excellence at it's best
I'm not any kind of an expert when it comes to nit-picking the fine details, but this 8.0 mm eyepiece outperforms every other eyepiece I currently own. I couldn't be happier.
OMG, the 8 Ethos.....what can I say. Finally Sunday night at midnight I set up FC-76 to try out the new 8 Ethos along with the 13 Ethos and compare them to the 8, 13, and 17 Baader Hyperions. The 8 just like its bigger sibling is just simply outstanding! Two things that immediately jumped out at me, the stars are tighter/sharper and brighter when comparing the Ethos to the Hyperions. The sharper star images make the stars appear brighter to my eyes. I have no idea many elements and or what sort of hybrid molded aspherics are in the Ethos according to the rumors of the design, but they just do not get in the way of the views. At f 7.9 in the FC76 s the stars looked sharp all the way out to the edge as you pan around to view the entire field. No trouble with blackouts and I can see the entire 100 AFOV at once, you just have to concentrate on the area within the field of view you want to study. Simply breathtaking! Granted the Ethos are several times more expensive than the Hyperions, so it may not be a fair comparison, but they are worth the price to me. Until you A-B the eyepieces, you just don't realize how sharp the Ethos are. I looked at Jupiter and even at only 75x with the 8 Ethos, I was shocked at how much detail I was seeing. I compared the Ethos to the 8 Hyperion, and when the seeing popped in, the Ethos WAS clearly the winner for contrast and finer detail in the belts and Polar Regions. I wanted to bump up the power, but now it was nearing 2 am, so I had to pack it in for the night, something called work at 7am was coming up in less than 5 hours. Man I can't wait to get out to a dark site to cruise the summer milky way with the Ethoses, or is it Ethoi :-. For an alt/az mount, there simply are no better eyepieces to use, period. What focal lengths will TV come up with next?
