Product Description

Explore Scientific 82° Eyepiece Set with Soft Sided Case

Explore Ultra-Wide Eyepieces - Comfort, Quality, Value. Explore Scientific 82° Series™ eyepieces, with their 82° apparent field of view, immerses you in a very comfortable ultra-wide field that naturally promotes relaxation at the eyepiece. When you relax your eyes and take in the scene displayed before you, it is much simpler to observe for more timeframes, and points of interest start to emerge that might not have been to obvious to you at the first look. Another extraordinary advantage of ultra-wide eyepieces is the simplicity with which you can observe, not directly at an object, but rather slightly to each side. This skill, known as averted vision vision, is particularly useful when looking at faint celestial objects since it exposes the part of your eye that is more sensitive to light, allowing fainter objects to appear. 

Protection from the Outdoors - By making the eyepiece body Argon-purged, the waterproof eyepiece internal elements will remain as pristine as the day they were assembled.

Argon particles are "bigger" than that of Nitrogen and in this manner they are less inclined to "leak" or diffuse their way through the seals over the life of the eyepiece. The atomic radius of Argon is bigger than Nitrogen by 0.13 angstroms and has a bigger atomic volume by 11.2 cubic centimeters/molecule. Argon additionally has superior inertness versus Nitrogen (i.e. forming few or no chemical compounds with other elements) that prevents adverse responses with eyepiece components  and 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 is impenetrable to internal fogging and contaminants, for example, fungus developing in the middle of the lens components. The waterproof eyepiece is simpler to clean, and there is no risk of cleaning solution from the top of the lens and seeping around edges to be caught in the middle of components. To safeguard an impeccable seal Explore Scientific tests each eyepiece in one meter of water for 30 minutes.
