Product Description

Explore Scientific's 82° Series argon-purged waterproof extreme wide field eyepieces are optimized to produce high contrast, high resolution, and superior flat field characteristics. They use advanced computer design, combinations of low dispersion and high refractive index optical glasses, and durable multilayer deposition coatings to provide a visual effect that is truly a full-immersion experience. The long eye relief 82° Series eyepieces come with a removable and foldable soft silicone rubber eyecup 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.

Sealing the eyepiece body and then purging it of all moisture with argon, assures that the eyepiece internal elements will remain as pristine and waterproof as the day they were assembled.

Argon atoms are "larger" than that of nitrogen and therefore they are less likely to "leak" or diffuse their way through the seals over the life of the eyepiece. Argon also has superior inertness vs nitrogen (i.e. forming few or no chemical compounds with other elements) that prevents adverse reactions with eyepiece components and therefore extends the longevity of the internal components. It also prevents chemical reactions with other elemental contaminants that may be introduced through a weakened seal. And, finally because argon is less conductive of heat than nitrogen, argon cools slower, thereby buffering the effects of rapid temperature changes of the optics.

The sealed, dry environment of the Explore Scientific 82° eyepiece is impervious to internal fogging and contaminants such as fungus growing in between the lens elements. The 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.

This Explore Scientific 82° eyepiece kit includes 1.25" 82° 6.7mm, 11mm, 18mm argon-purged waterproof eyepieces, a 2" 82° 30mm argon-purged waterproof eyepiece, plus a soft sided case with space for additional eyepieces and accessories as shown in the feature image above. These eyepieces come individually boxed in Explore Scientific's famous Will Tirion star map boxes along with the soft-sided case inside an outer box.

I bought this set of eyepieces as my first set of "Quality" eyepieces. I have not been disappointed. The quality of construction and the perfection of the optics are great and the eyepieces have added immensely to my enjoyment of the hobby. (Posted on 10/23/2019)

I bought this set for use with my ES 102mm FCD-100 APO refractor and couldn't be happier with the quality. The field of view is ideal and the views are spectacular. The bag offers great protection for the eyepieces and just enough extra space for some other small miscellaneous items I frequently use. (Posted on 10/24/2018)
