The 1.25" diameter barrel 82° Series 8.5mm Eyepiece from Explore Scientific is engineered to deliver a wide field of view with a long eye relief, making it ideal for planetary and deep-space observations. Its long eye relief makes it extremely comfortable during long observation sessions while offering you the ability to utilize the averted vision techniques that allow you to see faint details of elusive objects like wispy nebulae and galaxies. Viewing comfort is also optimized for eyeglass wearers.

Proprietary EMD anti-reflective multi-coatings ensure bright, high-contrast images with true color transmission across the entire wide field of view. To keep internal reflections to a minimum and improve contrast, the inside of the barrel is blackened, as are the edges of the lenses, to minimize the scattering of light within the lenses themselves. A fold-down rubber eyecup prevents stray light from leaking into the eye, further boosting contrast.

All eyepieces in the 82° Series are parfocal, so there will be little to no need to refocus when moving from one focal length to the next. This 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.
