  • "I just recently purchased my first E.S. telescope after owning a couple fantastic E.S. eyepieces. I have the 6.7mm & 30mm 82° eyepieces and they are my go-to picks for wide field and high power. They are a perfect match for my new E.D.127mm refractor." - Greg McKay

    The Explore Scientific 30mm 82 Degree Series Waterproof Eyepiece is often referred to as a benchmark-quality eyepiece by experienced deep sky observers. It's generous 22mm of eye relief provides the eye comfort desired by deep-sky observers, and still provides the 82 degree apparent field of view even with eyeglasses on. Using advanced computer design, combinations of low dispersion and high refractive index optical glasses, and durable EMD Enhanced Multilayer Deposition coatings, this Explore Scientific Argon-Purged 82° Series™ ultra wide field eyepiece is optimized to produce high contrast, high resolution, and superior flat field characteristics.

    The visual effect of these eyepieces with their long eye-relief and their 82° apparent field is truly a full-immersion experience. Your eye is relaxed, allowing you to easily use the "averted vision" technique to study faint details across a huge field-of-view. Explore Scientific 82° Series™ eyepieces, with their 82° apparent field of view, immerses you in a very comfortable ultra-wide field that naturally promotes relaxation at the eyepiece. When you relax your eyes and take in the scene presented before you, it is much easier to observe for longer periods of time, and details begin to materialize that may not have become apparent to you at first glance. 

    Use with the Explore Scientific 2X Focal Extender (2.0-inch O.D.) to double the magnification of this eyepiece (making it an effective 15mm focal length) while maintaining the same eye relief and apparent field.
