Description:The Tele Vue Ethos eyepieces have pushed the boundries of optical excellence and maximum field of view, creating an unrivaled eyepiece experience. The Tele Vue 17mm Ethos is the latest in the Ethos family of eyepieces, providing an even larger field of view than the original 13mm.

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 17mm Ethos delivers: 100° apparent field (50% larger in area than 82° Naglers), 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.

TeleVue Ethos 17mm
I am giving this outstanding eyepiece a 9 overall rating only because of price. The optics are in a class of its own. WOW is an understatement.

I have looked thru the Explore scientific 14mm 100 degree eyepiece, and was very impressed with the view, it is a fine eyepiece! but if you ever look thru the 17mm Ethos beware! get your wallet out and be ready to lighten it up a bit.

The correction in a fast 4.9 Newt is nothing but unbelievable. Pin point stars in all but the outer portion of the view.

Like I said nothing wrong with the Explore Scientific, If it was all I could afford I would have one, but if you can afford the extra expense, by all means get you one of these

TeleVue Ethos 17mm
Although I have several Ethos eyepieces in my case, 6mm (just ordered), 8mm, 13mm, 17mm & 21mm, the 17mm is quickly becoming my favorite. This eyepiece seem to fit my scope (16" F4) perfectly. It has become my go to eyepiece and as of late has been spending the most time in the focuser along with the Parracor Type 2. M42 and open clusters are framed perfectly. I love it and I don't see me getting rid of it any time soon.
