The 68° Series 34mm combines a long focal length, 2" barrel, and lanthanum glass optics for expansive deep-sky views with the edge-to-edge sharpness that serious observers demand. At this focal length, the 68° field frames large swaths of sky — sweeping through star clouds, open clusters, and extended nebulae becomes a genuine pleasure. Waterproof construction and EMD coatings at this price point make it a strong value against higher-priced competitors.

Key Features

• 2" barrel for maximum field of view and light throughput at long focal lengths
• Multi-element lanthanum glass optics — dense crown, light crown, dense flint, and lanthanum glasses deliver sharp, well-corrected images to the field edge
• 68° apparent field of view — wide, immersive framing ideal for large deep-sky targets and rich star fields
• Argon-purged waterproof housing — sealed against moisture, fog, and temperature changes for reliable all-season performance
• Enhanced Multi-Layer Deposition (EMD) coatings on all air-to-glass surfaces with edge-blackened elements for contrast
• Fold-down silicone rubber eyecup with generous eye relief for comfortable extended viewing, including with eyeglasses

Ideal For

• Wide-field deep-sky observers who want to frame large nebulae, open clusters, and Milky Way star fields with sharp, well-corrected optics
• Dobsonian and large-aperture telescope owners where a 34mm provides comfortable low-power views with enough magnification to show structure in extended objects
• Milky Way scanning and rich star field sweeping where the combination of brightness, field width, and lanthanum glass sharpness is at its best
