Description
The Explore Scientific 68° Series 40mm Waterproof Eyepiece is built for astronomers who want a wide, immersive view that survives outdoor conditions. It suits visual observers who leave gear set up outside for extended sessions and want internal optics protected from moisture and fungus. An argon-purged, sealed design keeps the eyepiece performing like new for years.
- Argon-Purged Waterproof Design: Sealed and argon-purged to resist fogging, leaks, and internal fungus growth, tested submerged for 30 minutes.
- 68° Apparent Field of View: A wide 68-degree apparent field gives a full-immersion viewing experience.
- Parfocal Across Focal Lengths: Stays in near focus when switching between eyepieces of different focal lengths in the same series.
- 31mm Eye Relief: Long eye relief with a removable, foldable silicone eyecup keeps viewing comfortable.
