Tele Vue Ethos Overview

With its exceptional apparent angle of view, the Tele Vue Ethos 13mm Ultra Wide-Angle Eyepiece offers views with high contrast and excellent on-axis sharpness; and virtually zero astigmatism or field curvature across its expansive 100° field of view.

Combining a hyper-wide apparent angle of view with its medium focal length, this Ethos delivers moderate magnification for most general observation needs on near and deep-sky objects alike — while still offering an expansive and immersive observational experience. This eyepiece is parfocal with the 10mm Ethos, thus requiring little or no refocusing when changing between the two, and it also accepts astigmatism-correcting DIOPTRX diopters to further improve the view.

A unique design characteristic of this Ethos allows it to be used with smaller, more common-sized, 1.25" drawtubes and accessories; and  larger 2" versions. This provides users with an easy and convenient way to expand its functionality and versatility, without limiting its use or relying on eyepiece holder reducer adapters.

how do you know what type of eye piece works best ...

how do you know what type of eye piece works best with your telescope? Is there a rule or formula to calculate it, if you work with refractor/reflector, and if you add a barlow lens?
Asked by: Tal
For example, to calculate maximum power of a telescope, a 90mm diameter scope will have a 180 maximum power. Please call in for further info .

Hello,Is this lens compatible with the Celestron 6SE telescope?Many thanks
Asked by: Colin D.
I bought the lens about a month but have no chance to view through it yet. However I did try fitting it to my Celestron 8SE telescope which has a 1.25 diagonal and I did not have any problem.
