The Explore Scientific 6.5mm 82° Series Long Eye Relief Eyepiece offers high magnification power with outstanding visual comfort, thanks to its generous 16.8mm of eye relief—a key feature for eyeglass wearers who want to take in the full field without strain.
With its 6.5mm focal length, this eyepiece is ideal for viewing planetary detail, lunar terrain, tight double stars, and bright deep-sky objects under excellent seeing conditions. It delivers high-resolution, contrast-rich views, making it perfect for close-up exploration of features like Jupiter’s belts, Saturn’s Cassini Division, or nebular structure in rich star fields.
Crafted with low-dispersion, high-index optical glass, each element is fully multi-coated with Enhanced Multi-layer Deposition (EMD) coatings and edge-blackened to reduce glare and maximize contrast. The 82° apparent field of view offers an immersive, wide-angle experience that promotes averted vision techniques for observing faint detail at the edge of visibility.
Built to withstand tough observing environments, the eyepiece is argon-purged and O-ring sealed, ensuring waterproof, fog-resistant, and contaminant-proof performance. It’s rugged, easy to clean, and engineered for years of crisp, reliable viewing.
