Explore Scientific Eyepiece 82° Ar 8,8mm 1.25"

Utilizing state-of-the-art computer design, a blend of low dispersion and high refractive index optical glasses, and robust multilayer deposition coatings, Explore Scientific's 82° Series extreme wide-field eyepieces are finely tuned to deliver outstanding contrast, resolution, and a flat field.

The immersive effect of these eyepieces, with their extended eye-relief and expansive 82° apparent field, offers a truly engrossing experience. Your eyes relax, enabling effortless utilization of the "averted vision" technique to explore faint details across an expansive field-of-view.

Each eyepiece undergoes meticulous assembly into precision machined metal lens barrels, maintaining perfect optical alignment for enduring field use. Featuring a fold-up rubber eye-guard for customizable comfort, these eyepieces prioritize observer comfort, crucial for prolonged astronomical observation.

To minimize internal reflections, all internal surfaces of the eyepiece barrel and lens edges are coated in flat black, reducing light scattering within the lenses.

Outdoor protection is assured with argon-purged and waterproof construction, ensuring internal elements remain pristine against fogging and contaminants. This waterproof design facilitates effortless cleaning without the risk of cleaning solution seepage between lens elements.
