Transform Your Viewing Experience

The Explore Scientific 100° Series Eyepiece not only offers a hyper-wide field of view but also introduces ease and comfort to your stargazing adventures. Its vast apparent field of view not only presents a panoramic spectacle but also relaxes the eye, allowing for longer, more detailed observation sessions. Observers can utilize averted vision techniques more effectively, revealing faint celestial wonders with surprising clarity.

Durability Meets Innovation

Every eyepiece in the 100° Series is rigorously tested, ensuring resilience against water ingress up to 1 meter for 30 minutes. The argon-purging process prevents internal fogging and maximizes the longevity of the coatings, ensuring that each viewing experience is as breathtaking as the first.

Your Companion in the Quest for the Cosmos

Whether you're scanning the Milky Way's edges or exploring distant galaxies, the Explore Scientific 100° Series Eyepiece is your reliable companion. It’s more than just an eyepiece; it’s your portal to the universe.
