Explore Scientific 11mm 82 Degree Series 1.25 Inch Waterproof Eyepiece
Using advanced computer design, combinations of low dispersion and high refractive index optical glasses, and durable multilayer deposition coatings, Explore Scientific 82 Degree 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 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.
Each 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.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.
Limited Warranty is one year, which converts to the Explore STAR Transferrable Extended Life of the Product Warranty when product is registered within 60 days of purchase.
Developing our new eyepieces we wanted to take a fresh perspective and address several points. Our goal was to produce an ultra-wide angle design that provides pride of ownership at a great value:
Focus on Value - We invite direct comparison to any eyepieces on the market in their category.
Protection from the Outdoors - By making the eyepiece body argon-purged and waterproof eyepiece internal elements will remain as pristine as the day they were assembled. The sealed, dry environment is impervious to internal fogging and contaminants such as fungus growing in between the lens elements. Our waterproof eyepiece is easier to clean, and there is no risk of cleaning solution migrating from the top of the lens and seeping around edges to be trapped in between elements. To insure a perfect seal we test every eyepiece in one meter of water for 30 minutes.
Creating an Identity - We look at purchasing fine optical equipment as an investment, and it should be treated as such. With a unique serial number on each eyepiece we can track when a product was made, and the owner can document their equipment for insurance and warranty purposes.
Providing Peace of Mind - Explore Scientific stands behind our products with the free Explore STAR Transferrable Extended Life of the Product Warranty upon registration of the product. Want to trade or sell your eyepiece? You’ll get more value if its remaining warranty can be transferred to the new owner.
All Explore Scientific telescopes and 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 Explore STAR by simply filling out the product registration and submit it in 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, and we'll take care of the rest.
