The 68° Series 16mm uses a multi-element lanthanum glass optical design that delivers noticeably sharper, higher-contrast views than simpler eyepiece designs. At 68°, the field of view is meaningfully wider than standard Plössl or 52° eyepieces — you see more sky in every glance. Argon-purged waterproof construction and EMD coatings at $109 make this a serious mid-range performer.
Key Features
- 6-element lanthanum glass optics — dense crown, light crown, dense flint, and lanthanum glasses work together for sharp, color-corrected images across the field
- 68° apparent field of view — a significant step up from 52° designs, providing wide, immersive views that make tracking objects easier
- Argon-purged waterproof housing — sealed against moisture, fog, and humidity for reliable all-weather performance
- 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 eye relief during extended sessions
- 1.25" barrel fits standard focusers on all common telescope types
Ideal For
- Deep-sky and planetary observers who want a medium-power eyepiece with wider, sharper views than basic designs can offer
- Observers upgrading from Plössl or 52° eyepieces — the jump to 68° with lanthanum glass is immediately noticeable
- All-around use at star parties, outreach, or personal sessions where a single versatile eyepiece needs to perform well on multiple targets
