Imagine observing the turbulent storms on Jupiter or the razor-sharp edges of Saturn’s rings with stunning precision. The Explore Scientific 52° Series 1.25" 3mm Waterproof Eyepiece is designed for serious astronomers who demand high-powered, ultra-detailed views of the cosmos. With a precise 3mm focal length, this eyepiece delivers magnifications of up to 405X on a telescope like the ED152 at f/8, or 160X with an ED80 at f/6, allowing you to explore planets, double stars, and bright deep-sky objects like never before.

Do you struggle with blurry or washed-out images when pushing your telescope to higher magnifications? The Enhanced Multi-Layer Deposition (EMD) Coatings on this eyepiece minimize reflections and increase light transmission, so you get sharp, bright, high-contrast visuals even when viewing faint objects. Its edge-blackened lenses eliminate stray light, making sure every detail of the celestial object stands out with exceptional clarity. Whether you’re watching the intricate cloud bands on Jupiter or the delicate structure of the Orion Nebula, you’ll enjoy a level of clarity that lesser eyepieces simply can’t match.

Unlike other high-powered eyepieces that limit your perspective, the 52° apparent field of view in this eyepiece ensures a broad, immersive view of the sky. Tracking fast-moving objects, like planets or the Moon, becomes much easier and more enjoyable with this wider field of vision. You’ll also appreciate the generous 15mm eye relief, making extended stargazing sessions far more comfortable. Whether you wear glasses or not, the fold-down eyecup provides flexibility, reducing eye strain and allowing you to focus on what really matters—the wonders of the universe.

Are you tired of fogged lenses or equipment damaged by moisture? The argon-filled, waterproof, and fog-proofconstruction ensures that your eyepiece performs perfectly, no matter the environment. Whether you're observing in a humid coastal region, during a dew-laden evening, or at a high-altitude location prone to temperature changes, this eyepiece is built to last. Its slip-resistant textured surface guarantees a secure grip, even in wet conditions, so you can confidently use it no matter where you are.

Best of all, the 1.25" barrel size ensures compatibility across a wide range of telescopes, from entry-level models to advanced setups, without the need for a Barlow lens or focal extender. It’s a powerful upgrade that enhances your telescope’s performance instantly, giving you access to high magnifications without complicating your setup. If you’re ready to transform your observations with high-powered, crystal-clear views, the Explore Scientific 3mm Eyepiece is the key to unlocking the universe’s finest details, no matter the conditions or equipment you have.
