The 82° Series 11mm is a versatile high-power eyepiece with ultra-wide-field views that performs brilliantly on planets, the Moon, and brighter deep-sky objects alike. The 7-element lanthanum glass design delivers sharp, well-corrected images across the full 82° field — performance the community regularly compares to Tele Vue Naglers at roughly one-third the price. Waterproof and EMD-coated at $139.

Key Features

• 82° apparent field of view — immersive, ultra-wide views for effortless object tracking and a "spacewalk" observing experience
• 7-element lanthanum glass optics — sharp, color-corrected images with strong edge performance even in fast telescopes
• Argon-purged waterproof housing — sealed against moisture, fog, and humidity for all-weather reliability
• Enhanced Multi-Layer Deposition (EMD) coatings on all air-to-glass surfaces with edge-blackened elements
• Fold-down silicone rubber eyecup for comfortable eye relief during extended sessions
• 1.25" barrel fits standard focusers across all telescope types

Ideal For

• All-around observers who want a single high-power eyepiece that handles planets, the Moon, and bright deep-sky objects with an ultra-wide field
• Observers seeking Nagler-class performance at a fraction of the cost — the 82° series has earned a strong reputation for punching above its weight
• Fast-telescope owners (f/5 and below) where the 82° series' optical correction handles challenging focal ratios well
