Product Description

Explore Scientific 18mm 82º Argon Purged Waterproof 2" Eyepiece

This Explore Scientific 18mm 82º Argon-Purged Waterproof 2" Eyepiece has a focal length of 18 mm and a 2" barrel size.

Using advanced computer design, combinations of low dispersion and high refractive index optical glasses, and durable multilayer deposition coatings, Explore Scientific 82° Series extreme wide field eyepieces are 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. These eyepieces come 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.

Explore Scientific eyepieces are covered under a standard U.S.A. One Year Limited Warranty against defects with proof of purchase, but you can extend this limited warranty to five years by simply filling out the product registration and submitting it to Explore Scientific within 60 days.
