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 25mm 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

Low-power, ultra-wide scanning of large-scale deep-sky structures and the milky way. 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.

Good gift, and conversation starter with teenager
Format: Paperback
My 14 yr old really liked the gift, and he's not a reader. I do make it interactive, ask him questions and have conversations. I recommend.

Bought this as a gift for my son and it’s been a great addition. It naturally opens up conversations between us without feeling forced, which I really appreciate. It’s engaging, thoughtful, and something we actually look forward to using together. Definitely a meaningful gift if you’re trying to connect more with your kids.
