With its exceptional 100° apparent angle of view, the Tele Vue Ethos 10mm Ultra Wide-Angle Eyepiece offers a comfortable eye-relief despite the short focal length, with high contrast and excellent on-axis sharpness; and virtually zero astigmatism and field curvature across its expansive 100° field of view. Combining a hyper-wide apparent angle of view with its shorter focal length, this Ethos delivers high magnification for enhanced detail on near and deep-sky objects alike while still offering an expansive and immersive observational experience. This eyepiece is parfocal with the 13mm 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.

This 2” barrel Ethos includes a 1.25” screw-on adapter, which also allows the use of smaller, more common-sized 1.25” drawtubes and accessories. 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.

    Rated 5 out of 5 by from Televue Ethos 10MM Lens is Awesome! I have been wanting this lens for about 6 months and found that B&H had the best price bar none...I purchase it and had to wait a few weeks to put it into my 10 Skyquest Orion Dobsonian Telescope and WOW.. the bands on Jupiter and the moons of Jupiter were clearly visible and I had a very much larger field of view and wasn't chasing the planet every 5 seconds... by having to reorient the scope. Thanks to Al Nagler at Televue and B&H for bringing this lens to market and thinking of us amatuer Astronomers that are trying to make the bsst of the telescopes we have...

    Rated 5 out of 5 by from What can I say, Awesome! I recently got to use my new Ethos 10mm at the 4th annual Flagstaff Star Party where I was a telescope host. The eyepiece produces a 200X image in my non computerized 17.5 Dobsonian scope. The images were crisp and the ultra wide field(100 degrees) allowed ample time for up to two people to climb the ladder and see the object in the scope before it drifted out of the field (due to the rotation of the earth). Over 3 nights we had over 3000 people at the star party, and this seemingly endless line of people all had something wonderful to say about the beautiful images. It was only rare person, usually a young child, that had any trouble at all looking into the eyepiece and seeing the image. It is true that the quality of the eyepiece is just as important as the telescope's mirrors. In this case you get what you pay for and so much more.
