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
