Explore Scientific 82 Degree Argon Eyepiece 24mm 2 Inch

Explore Scientific 82 degree series extreme wide field eyepieces are optimized to produce high contrast, high resolution, and superior flat field characteristics. Ideal for low power, widefield work, this 24mm 82 degree 2 inch design is completely waterproof, meaning it will not fog up in moist conditions, is impervious to dew and can even be cleaned and rinsed underwater. The visual effect of these eyepieces with their long eye-relief and their 82 degree 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. The 82 degree Series eyepieces come with a twist-up rubber eye-guard that raise to the desired height for the comfort of the observer, and as experienced astronomers know, eye comfort is critical when trying to observe at the visual limits of the telescope. To keep internal reflections to a minimum, all internal surfaces of the eyepiece barrel are flat black, as well as the edges of the lenses themselves to minimize the scattering of light within the lenses themselves.
