Description
The Explore Scientific 68° Series 20mm Waterproof Eyepiece is an argon-purged, wide-field eyepiece built for astronomers who observe in the field, where fogging and moisture are real risks to an eyepiece's internal elements.
The 68° apparent field and long eye relief make for a full-immersion view at the eyepiece, and the design is parfocal with the rest of the 68° Series so you stay close to focus when swapping focal lengths.
- 68° Apparent Field: wide-field optical design for a full-immersion viewing experience.
- Argon-Purged Waterproof: argon-purged sealed housing tested underwater for 30 minutes at one meter of depth to guard against internal fogging and fungus.
- Parfocal Design: stays close to focus across the 68° Series when swapping between focal lengths.
- Eyecup: removable, foldable soft silicone rubber eyecup for observer comfort.
