Explore Scientific 100 Degree Series 3-inch 30mm Waterproof Eyepiece - EPWP10030-01

Presenting the Explore Scientific 100° Series 3" 30mm Waterproof Eyepiece, a pinnacle of hyper-wide class oculars designed to revolutionize your visual astronomy experience.

This eyepiece redefine boundaries, offering an astonishingly wide expanse of the celestial canvas.

The initial gaze through a 100° Series eyepiece is akin to a cosmic revelation, where the eyepiece seemingly vanishes, leaving only the boundless universe in view.

Boasting an apparent field of view nearing the upper limit for hyper-wide designs, object location becomes seamless.

Even in non-driven telescopes, celestial objects remain comfortably framed within the field of view for extensive periods before necessitating any adjustments.

A remarkable advantage of hyper-wide eyepiece lies in their facilitation of averted vision, allowing you to subtly shift your gaze.

This technique, leveraging the more light-sensitive area of your eye, proves invaluable when observing faint celestial entities, enabling you to discern even the most delicate intricacies.

Moreover, the Explore Scientific 100° Series 3" 30mm Waterproof Eyepiece features a precision-engineered 3" barrel, ensuring seamless compatibility with large-format eyepiece holders.

This enables seamless integration with telescopes equipped to accommodate larger eyepieces.

Each eyepiece undergoes rigorous internal sealing and purging, utilizing dry, inert argon gas.

This process ensures waterproof performance, preventing internal fogging and safeguarding against particulate intrusion and fungal growth.

It further enhances the eyepiece's durability and extends the life of internal coatings.

To validate their waterproof capabilities, every 100° Series eyepiece undergoes a stringent submersion test, enduring water depths of up to one meter for a duration of 30 minutes.

Incorporating cutting-edge optical technology, precision craftsmanship, and a robust waterproof design, the Explore Scientific 100° Series 3" 30mm Waterproof Eyepiece stands as a testament to the brand's commitment to providing astronomers with unrivaled viewing experiences.

Whether you're an experienced stargazer or an enthusiastic beginner, this eyepiece is poised to elevate your observations to new heights, offering comfort, quality, and extraordinary value in one celestial package.



  • 100° Apparent Field of View: The eyepiece offers an extraordinary 100-degree apparent field of view, providing observers with a panoramic visual experience that immerses them in the celestial landscape. This wide field not only enhances aesthetics but also promotes relaxation of the eye, enabling astronomers to focus on subtle celestial details for extended periods without discomfort.
  • 30mm Focal Length (3-inch): With a 30mm focal length, this eyepiece is designed for large-format eyepiece holders, ensuring seamless compatibility with telescopes equipped to accommodate larger eyepieces. The generous focal length strikes a balance between magnification and field of view, making it suitable for a wide range of celestial observations, including detailed lunar and planetary study, as well as deep-sky exploration.
  • Argon-Purged Waterproof Design: Each eyepiece undergoes a meticulous internal sealing and purging process with inert, dry argon gas. This innovative design not only ensures waterproof performance, preventing internal fogging, but also serves as a safeguard against the intrusion of fine particulates and fungal growth. Additionally, this construction maximizes the lifespan of the internal coatings, preserving optical performance and durability.
  • Rigorous Water Testing: To validate their waterproof capabilities, every 100° Series eyepiece undergoes a rigorous submersion test. Each eyepiece is submerged in water up to a depth of one meter for a duration of 30 minutes. This stringent testing procedure guarantees the eyepiece's ability to withstand various environmental conditions, including damp or humid observing environments.
  • Fully Multi-Coated Optics: The optical elements of the 100° Series 3" 30mm Waterproof Eyepiece feature multiple layers of anti-reflective coatings. These coatings are applied to each optical surface to maximize light transmission while minimizing glare, reflections, and internal scattering. The result is exceptionally clear and bright views of celestial objects with enhanced contrast.
  • Edge-Blackened Optics: The optical elements of the eyepiece undergo an edge-blackening process, further enhancing image quality. This process reduces internal reflections and stray light, leading to increased contrast and improved image sharpness. The elimination of unwanted light artifacts ensures that celestial objects appear with exceptional clarity.
  • Precision-Machined Metal Construction: Each eyepiece in the 100° Series is meticulously crafted with precision-machined metal components. This construction ensures durability and longevity, making these eyepieces reliable companions for years of stargazing adventures. The robust design also maintains optical alignment, guaranteeing consistent performance over time.
  • Threaded Barrels: The eyepiece barrels are threaded to accommodate filters, allowing users to enhance their observations by adding various astronomy filters. This feature enables astronomers to customize their viewing experience and adapt to specific celestial targets and conditions.
  • Comfortable Eye Relief: The eyepiece provides comfortable eye relief, accommodating observers who wear eyeglasses. This extended eye relief allows for relaxed and immersive viewing without the need to remove eyeglasses, enhancing the overall observing experience.
  • Wide Compatibility: The Explore Scientific 100° Series 3" 30mm Waterproof Eyepiece is compatible with a variety of telescope types and mounts, making it a versatile addition to any astronomer's equipment arsenal.
