What sets the Explore Scientific 68 Degree Series 16mm Argon Purged Waterproof Eyepiece apart is its combination of high-quality construction, long eye relief, and wide field of view. Designed for astronomy enthusiasts who value comfort and clarity, this eyepiece is perfect for extended celestial observation sessions.

The eyepiece boasts a 16mm focal length and a 68-degree apparent field of view, providing a panoramic view of the night sky. This wide-angle view is ideal for observing large celestial objects or areas, making your stargazing experience more immersive.

The eyepiece is also designed with long eye relief, making it a preferred choice for eyeglass wearers. With over 16mm of eye relief, you can comfortably observe the cosmos without straining your eyes.

The Explore Scientific 68 Degree Series Eyepiece is not just about comfort and view, it's also built to last. The eyepiece is argon purged and waterproof, making it rugged and durable enough to withstand outdoor environments. This feature ensures that your eyepiece remains fog-free and protected from the elements, providing clear, sharp images regardless of the weather conditions.

The 1.25" barrel size is compatible with most telescopes, making this eyepiece a versatile addition to your astronomy equipment. The eyepiece also features a rubber grip and folding eyecup for added comfort and ease of use.

Enhanced with EMD coatings, this eyepiece offers superb contrast, allowing you to see the faintest objects that your telescope is capable of. Whether you're a seasoned astronomer or a beginner, the Explore Scientific 68 Degree Series 16mm Argon Purged Waterproof Eyepiece is a valuable investment for your stargazing adventures.

  • Durable Coatings and Finishing Touch: Each element in your Explore Scientific 68 Degree Series 16mm eyepiece is fully multi-coated, resulting in bright, sharp images and every element has blackened edges to reduce internal reflections and increase contrast
  • Waterproof, Fog Proof Housing: The internal optics of 68 Degree Series 16mm eyepiece is housed in a gas purged, waterproof barrel that keeps them as pristine as the day they were manufactured
  • Tapered Barrel for Extra Security: The insert barrel of 16mm eyepiece is double tapered to allow smooth insertion, the wide dimension of the taper helps prevent the eyepiece from falling out of the telescope should the set screw holding it in place become loose
