Explore Scientific 92° ED Series 9mm Waterproof EyepieceUltra wide field eyepieces at the 92 class have traditionally been heavy, expensive, and limited to a few focal lengths.

Ultra-wide-field eyepieces at the 92° class have traditionally been heavy, expensive, and limited to a few focal lengths. The Explore Scientific 92° ED Series 9mm Waterproof Eyepiece delivers a 92° apparent field of view with extra-low dispersion glass, waterproof argon-purged construction, and long eye relief — immersive panoramic viewing without the weight premium of older ultra-wide designs.
The ED glass reduces color fringing that plagues standard ultra-wide eyepieces, especially at the field edges where chromatic aberration is most visible. At 92°, the apparent field is wide enough to create a genuine sense of being immersed in the star field rather than looking through a window. The waterproof, argon-purged housing is built for all-night sessions regardless of humidity or dew conditions.
Key Features
- Extra-low dispersion glass — minimized chromatic aberration for clean, high-contrast views across the full 92° field
- 92° apparent field of view — among the widest available, creating a truly immersive observing experience
- Waterproof and argon-purged — sealed against moisture and internally fog-proof
- Long eye relief — comfortable for extended sessions and eyeglass-compatible
- 2" barrel — maximum light throughput and field stop diameter for ultra-wide-field performance
- Enhanced multi-layer deposition coatings on all air-to-glass surfaces
Ideal For
High magnification with an immersive, ultra-wide field — planetary detail surrounded by context. The 92° field transforms the observing experience — targets fill the eyepiece rather than floating in empty space. An ideal upgrade for Dobsonian owners, deep-sky visual observers, and anyone who values the immersive experience of panoramic astronomical viewing. Compatible with any telescope accepting 2" eyepieces — simply drop in and observe.
