With the Explore Scientific 68 Degree Series 34mm Argon-Purged Waterproof Eyepiece, you can elevate your astronomical observation experience to new heights. This high-quality eyepiece is meticulously designed for astronomy enthusiasts who value longer eye relief and a wider field of view, surpassing the capabilities of traditional Plossl or Orthoscopic style eyepieces.

Ideal for eyeglass wearers, this eyepiece features an extra-long eye relief, allowing you to keep your glasses on while observing comfortably. The 2-inch barrel and 34mm focal length make it a versatile choice for both terrestrial and celestial observation, offering a broad and immersive view of the sky.

This rugged eyepiece is not just about performance, it also boasts durability and resilience. It's waterproof and argon-purged to prevent internal fogging, ensuring clear and sharp views even in humid conditions.

The eyepiece is further enhanced with EMD coatings for superior contrast, enabling you to discern the faintest objects that your telescope can detect. The rubber grip and folding eyecup add to its user-friendly design, making your stargazing sessions more enjoyable and less strenuous.

In essence, the Explore Scientific 68 Degree Series 34mm Argon-Purged Waterproof Eyepiece is a perfect blend of functionality, comfort, and durability, designed to optimize your telescope's performance and enhance your observation experience.
