    Why Buy From Backyard-Planet

    Explore Scientific 68° Series Waterproof Eyepiece

    Using advanced computer design, combinations of low dispersion and high refractive index optical glasses, and durable multilayer deposition coatings, Explore Scientific 68° Series Argon-Purged Waterproof extreme wide field eyepieces are optimized to produce high contrast, high resolution, and superior flat field characteristics. These eyepieces' visual effect with their long eye-relief and their 68° visual field is truly a full-immersion experience of the night sky when looking through this eyepiece.

    The 68° Series eyepieces are parfocal- meaning they focus at near the same point regardless of the focal length you select. They come with a removable and foldable soft silicone rubber eyecup for the comfort of the observer. As experienced astronomers know, eye comfort is critical when observing the visual limits of the telescope.

    Features:

    • The sealed, dry environment is impervious to internal fogging and contaminants such as fungus growing between the lens elements. 
    • Our waterproof eyepiece is easier to clean, and there is no risk of cleaning solution migrating from the top of the lens and seeping around edges to be trapped in between elements. 
    • To ensure a perfect seal, we test every eyepiece in one meter of water for 30 minutes.

    Available Sizes: 16mm, 20mm, 24mm, 28mm, 34mm, and 40mm
