Mfr. Part: EPWP8211-01
Description
Using advanced computer design, combinations of low dispersion and high refractive index optical glasses and durable multilayer deposition coatings, Explore Scientific 82deg. 11mm Argon-Purged Waterproof Eyepiece is optimized to produce high contrast, high resolution and superior flat field characteristics. The visual effect of this eyepiece with its long eye-relief and 82deg. 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.
This eyepiece is meticulously assembled into precision machined metal lens barrels that maintain the perfect alignment of the optical train for years of rugged use in the field. This eyepiece comes with a twist-up rubber eye-guard that raises 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 as well as the edges of the lenses are flat black to minimize the scattering of light within the lenses themselves.
