The 2" diameter barrel 92°-Series 17mm Eyepiece from Explore Scientific is a wide-field telescope eyepiece with eight optical elements. It is designed for planetary and deep-space observations. Its wide exit pupil and long eye relief makes this eyepiece ideal for comfortable viewing for extended periods. The contrast is enhanced by a fold-down rubber eyecup that prevents stray light from leaking into your eye.

Anti-reflective multi-coated optics ensures bright, high-contrast images with true color transmission across the entire wide field of view. The eyepiece features a textured surface for a sure-grip when changing it out, and it is argon-filled for water and fogproof performance when used in extreme temperatures and climates.

Wide 92° apparent field of view displays a broad image with minimal optical distortion, ideal for detailed observation
Images have true color transmission across the entire field of view, even as the observed object approaches the field stop.
Fold-down eyecup prevents peripheral light from leaking into your eye, causing blurring and dimming of the image

    92° Series 17mm Eyepiece (2") is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from Incredible all-around performer, eye placement is finicky Bought this eyepiece as a mid-power upgrade for my trusty 19mm Panoptic since it can give me a wider true field of view and more magnification and better eye relief all in one package. The views through it are stunning. It's sharper and more contrasty than the 19mm Panoptic. It's even a razor sharp planetary eyepiece which I was not expecting. Its sharpness and contrast revealed features in Jupiter's clouds that the 19mm Panoptic and 20mm Series 4000 Plossl I compared it with could not. There was no noticeable ghosting or light scatter - Jupiter was a crisp, clean orb just hanging out in a vast chasm of space. Using it in my 8 F/10 schmidt, the field is flat with no noticeable curvature. Stars exhibit coma at the edges, but that's due to the telescope, not the eyepiece. My only complaint is that eye placement is finicky in this eyepiece. Too close or too far away and you get blackouts. I would rate it as NOT comfortable to look through because of this, and takes a bit of getting used to, but once you do, it performs brilliantly.
