Explore Scientific 68° Series 1.25" 24mm Waterproof Eyepiece

The 68° Series 24mm delivers wide, bright deep-sky views through lanthanum glass optics in a 1.25" barrel — framing large targets at low magnification with the sharpness and contrast that simpler optical designs cannot match. Argon-purged waterproof construction at $109 makes this an exceptional value for quality wide-field observing.

Key Features

• Multi-element lanthanum glass optics — dense crown, light crown, dense flint, and lanthanum glasses produce sharp, well-corrected images to the field edge
• 68° apparent field of view — expansive framing for large deep-sky objects while maintaining a 1.25" barrel format
• Argon-purged waterproof housing — sealed against moisture and fog for confident observing in any 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 for comfortable extended viewing
• 1.25" barrel — delivers wide fields without requiring a 2" focuser

Ideal For

• Deep-sky observers framing large open clusters, nebulae, and galaxy groups at low power through a 1.25" focuser
• Wide-field scanning of the Milky Way, star clouds, and extended objects like the Veil Nebula where the 68° field and lanthanum glass sharpness really shine
• 1.25" focuser owners who want the best optical quality available in their barrel format before stepping up to 2" eyepieces
