All Explore Scientific telescope accessories are covered under our 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 submit it to Explore Scientific within 60 days. This program is also available to the person who receives your gift of an Explore Scientific telescope. You don't need to give them the purchase receipt, just remind them to fill out the registration and submit it to Explore Scientific and we will take care of the rest. 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. The 82° Series eyepieces come with a rubber eye-guard and as experienced astronomers know, eye comfort is critical when trying to observe at the visual limits of the telescope.
