The 82° Series 8.5mm LER hits the sweet spot of magnification and field width for high-power deep-sky observing, with Long Eye Relief that keeps extended sessions comfortable. The 82° field frames planetary nebulae, globular clusters, and tight galaxy groups with surrounding context that narrower eyepieces lose. Lanthanum glass optics and waterproof construction at $139 make this a standout value.

Key Features

• 82° apparent field of view — ultra-wide framing that provides context around your target and makes object-finding intuitive
• Long Eye Relief (LER) design — comfortable working distance for long sessions and easy eyeglass compatibility
• 7-element lanthanum glass optics — precision glass delivers sharp, color-corrected images to the field edge
• Argon-purged waterproof housing — sealed against moisture and fog for reliable all-weather observing
• Enhanced Multi-Layer Deposition (EMD) coatings on all air-to-glass surfaces with edge-blackened elements
• Fold-down silicone rubber eyecup and 1.25" barrel for standard telescope compatibility

Ideal For

• Deep-sky observers who want high-power views of planetary nebulae, globular clusters, and compact galaxy groups within an ultra-wide field
• Planetary observers who prefer moderate-high magnification with more sky context than standard eyepieces provide
• Eyeglass wearers who value the LER design for comfortable, full-field access at shorter focal lengths
