Product Description

Explore Ultra-Wide Eyepieces - Comfort, Quality, Value. The Explore Scientific 100° Series™ eyepieces are hyper-wide class oculars that can change your visual astronomy observation. You might be amazed at the amazingly wide field of inky dark sky you see the first occasion when you put your eye to a 100° Series eyepiece, and after awhile, you might even forget the fact that you have an eyepiece in the middle of you and the cosmos! With an apparent field of view that is near the maximum for hyper-wide eyepiece design, objects aren't only simpler to find, but for non-driven telescope the object will remain in the field of view for a long time before adjustment are needed.

Another awesome advantage of hyper-wide eyepieces is the simplicity with which you can look, not directly at an object, but slightly either side. This skill, called averted vision, is particularly useful when observing faint objects, since utilizing averted vision puts the picture on a piece of your eye that is more sensitive, allowing detection of fainter objects.

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.
