Explore Scientific 82° Series 30mm Waterproof Eyepiece

The Explore Scientific 82° Series 30mm Waterproof Eyepiece is an ultra-wide eyepiece built for observers who want a super-wide apparent field with generous eye relief at upper-medium magnification. It's aimed at anyone observing globular clusters, planetary nebulae, or initial planetary detail, where the 82° field promotes relaxed, extended viewing. Precision-machined metal barrels and enhanced multilayer coatings keep the optical train aligned for years of field use.

• 82° apparent field of view: Generous eye relief creates a full-immersion view that supports the averted-vision technique for faint detail.
• Waterproof, argon-purged construction: Built to hold up to field conditions including moisture.
• Precision metal lens barrels: Maintains optical alignment for years of rugged use.
• Flat-black internal surfaces: Minimizes internal reflections and light scattering within the eyepiece.
• Compatible with Explore Scientific Focal Extenders: Doubles, triples, or quintuples magnification while retaining native apparent field and eye relief.
