A Technological Marvel for Astronomical Exploration

Leveraging cutting-edge computer design and the finest optical materials, the 68° Series 34mm Eyepiece delivers a full-immersion visual experience, making it easier than ever to explore the night sky. The wide field of view not only enhances your ability to observe faint celestial objects but also supports the use of averted vision techniques, allowing you to perceive the subtlest details with ease.

Advanced Protection for Pristine Observations

The argon-purged construction of the eyepiece ensures that internal optics remain unaffected by external conditions. Argon's superior properties, including its larger atomic size and lower thermal conductivity, provide an optimal environment for the optics, minimizing the risk of internal fogging and thermal fluctuation impacts.

Maintenance Made Simple

Tested rigorously to guarantee a waterproof seal, this eyepiece is built for easy maintenance and durability. The design prevents contamination and simplifies cleaning, ensuring that your views remain clear and breathtaking, observation after observation.
