Explore Scientific 82° 4,7 mm extreme wide field eyepiece is optimized to produce high contrast, high resolution, and superior flat field characteristics.

The visual effect of this eyepiece with his long eye-relief and his 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° eyepiece comes 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.

Explore Scientific 82° 4,7 mm is fully multi-coated and edge-blackened to produce maximum contrast.
