Explore Scientific 25mm 100 Degree Series Argon-Purged Waterproof Eyepiece EPWP10025-01

Explore Ultra-Wide Eyepieces - Comfort, Quality, Value. The Explore Scientific 100° Series eyepieces are hyper-wide class oculars that can transform your visual astronomy experience. You may be startled at the amazingly wide expanse of inky black sky you behold the first time you bring your eye to a 100° Series eyepiece, and after awhile, you may even forget that you have an eyepiece between you and the universe! With an apparent field of view that is close to the maximum for hyper-wide eyepiece design, objects are not only easier to locate, but for non-driven telescopes the object will stay in the field of view for a very long time before any adjustments need to be made. Another great benefit of hyper-wide eyepieces is the ease with which you can gaze, not directly at an object, but slightly to either side. This skill, called using averted vision, is especially helpful when observing faint objects, because using averted vision puts the image on a part of your eye that is more sensitive to light, allowing you to see fainter images.

Hyper-Wide 100° Apparent Field of View: Provides an expansive, panoramic visual experience for an immersive stargazing experience. Averted Vision: Facilitates the use of averted vision to enhance the visibility of faint objects by focusing on a more sensitive part of the eye. Ease of Use: Objects stay in the field of view for extended periods, especially with non-driven telescopes, reducing the need for constant adjustments. Argon-Purged and Waterproof: Sealed and purged with dry argon gas for superior moisture protection and longevity. Tested to withstand submersion down to 1 meter for 30 minutes. Fully Multi-Coated Optics: All surfaces are multi-coated to maximize light transmission and contrast for clearer, brighter images. Edge-Blackened Lens: Helps improve contrast by reducing light scatter at the edges of the lens. Durable Design: Built to last with high-quality construction, making it ideal for both casual and serious astronomers.
