Explore Scientific 82° Series 2" 24mm Waterproof Eyepiece

The 82° Series 24mm delivers expansive deep-sky views through a 2" barrel with the ultra-wide 82° field and lanthanum glass sharpness that the series is respected for. At 24mm, the true field of view is wide enough to frame large nebulae and open clusters while still providing enough magnification to show meaningful structure. Argon-purged waterproof construction and EMD coatings at $229 position it well against 2" wide-field competitors costing considerably more.

Key Features

• 2" barrel for maximum field of view and light throughput
• 82° apparent field of view — immersive ultra-wide framing for large deep-sky objects with surrounding star field context
• 6-element lanthanum glass optics — sharp, color-corrected images with strong performance even in fast telescopes
• Argon-purged waterproof housing — sealed and fog-proof for reliable performance in all weather conditions
• Enhanced Multi-Layer Deposition (EMD) coatings on all air-to-glass surfaces with edge-blackened elements for high contrast
• Fold-down silicone rubber eyecup with generous eye relief for comfortable extended viewing, including with eyeglasses

Ideal For

• Wide-field deep-sky observers framing large nebulae, open clusters, and galaxy groups with sharp, well-corrected optics across the immersive 82° field
• Dobsonian and large-aperture telescope owners where a 24mm 82° provides a beautifully wide, detailed view at moderate-low magnification
• Experienced observers who have compared wide-field options and recognize the 82° series' value proposition against Tele Vue Nagler-class alternatives
