82° Series Waterproof Eyepiece
$139.00
Super-Wide 82° Views with Generous Eye Relief
The 82° Series delivers a super-wide apparent field alongside generous eye relief, a rare combination that makes extended observing sessions comfortable even at high magnification.
Advanced computer optical design combines low-dispersion, high-refractive-index glasses with durable Enhanced Multilayer Deposition (EMD) coatings and flat-black internal barrel surfaces for superior contrast and flat-field performance edge to edge.
The ultra-wide field makes averted vision techniques effortless for teasing out faint detail in globular clusters, planetary nebulae, and comets, while eight focal lengths cover everything from high-power planetary work to expansive deep-sky views.
