The 2" diameter barrel 82°-Series 18mm Eyepiece from Explore Scientific is a wide-field telescope eyepiece 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 multicoated 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 82° 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.
- Wide exit pupil and long eye relief ensure comfortable long-duration observation through your telescope
- Fold-down eyecup prevents peripheral light from leaking into your eye, causing blurring and dimming of the image
