Bresser EXPLORE SCIENTIFIC 82 Ar Eyepiece 4.7mm (1.25)

Explore Scientific 82 Series Extreme Wide Field Eyepieces

Explore Scientific 82 Series extreme wide field eyepieces are optimized to deliver high contrast, high resolution, and superior flat field characteristics.

Visual Experience

The visual effect of these eyepieces with their long eye-relief and an 82° apparent field of view provides a full-immersion experience. The relaxed eye position facilitates the use of the averted vision technique to study faint details across a vast field of view.

Comfort Features

The 82 Series eyepieces include a twist-up rubber eye-guard adjustable to the observer's preferred height, enhancing comfort during extended observation sessions. Eye comfort is critical for observing at the visual limits of telescopes.

Design and Coating

To minimize internal reflections, all internal surfaces of the eyepiece barrel and the edges of the lenses are flat black, reducing light scattering within the lenses. All 82 Series eyepieces are fully multi-coated and feature edge-blackened lenses to maximize contrast.
