The Explore Scientific 82° 2-Inch Waterproof Long Eye Relief Eyepiece Series delivers immersive wide-field views, exceptional optical performance, and durable weatherproof construction for serious visual observers. Designed with an expansive 82-degree apparent field of view, these eyepieces provide a space-walk experience ideal for deep-sky exploration, lunar detail, and planetary contrast.

Every eyepiece in this lineup features fully multi-coated optics, edge-blackened lenses, long eye relief, and precision-machined housings.
