Designed for deep sky adventurers and visual purists, the Explore Scientific 34mm 68° Series Eyepiece offers sweeping, immersive views with exceptional optical clarity and rugged durability. It's the perfect companion for observing large nebulae, dense star fields, and distant galaxies, providing a crisp, wide-field experience that captures the grandeur of the night sky.
Crafted with an advanced computer-optimized optical system, this eyepiece uses low-dispersion, high-refractive index glass combined with EMD (Enhanced Multi-Layer Deposition) coatings to deliver razor-sharp imagery, rich contrast, and flat field performance across the full 68° apparent field of view.
Its argon-purged, O-ring sealed construction makes it fully waterproof, protecting internal elements from fog, dust, and moisture. Each unit is submersion-tested at 1 meter for 30 minutes, ensuring long-term reliability in a wide range of observing conditions.
With a parfocal design, this eyepiece allows seamless transitions between focal lengths without constant refocusing. The generous 26.4mm of eye relief and removable flip-down silicone eyecup ensure maximum viewing comfort for all users, including eyeglass wearers.
