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

Introducing the Explore Scientific 100° Series 25mm Waterproof Eyepiece, a remarkable addition to the world of ultra-wide eyepieces set to revolutionize your celestial exploration.

These hyper-wide class oculars redefine the boundaries of visual astronomy, providing an immersive experience like no other.

As you peer through a 100° Series eyepiece, you'll be astounded by the vast expanse of velvety black sky stretching before you.

It's an unparalleled feeling of direct connection with the universe, where the eyepiece virtually disappears, leaving only the celestial wonders in your sight.

With an apparent field of view approaching the upper limit for hyper-wide eyepiece design, locating objects becomes a breeze.

Even for non-driven telescopes, celestial objects remain comfortably within view for extended periods before any adjustments are necessary.

Moreover, these hyper-wide eyepieces empower you to observe celestial objects not by gazing directly at them, but by slightly diverting your gaze to the side.

This technique, known as averted vision, proves especially valuable when observing faint objects.

Averted vision directs the image to a more light-sensitive part of your eye, enhancing your capacity to detect even the faintest celestial details and elusive targets.

Incorporating cutting-edge optical technology, precision craftsmanship, and a robust waterproof design, the Explore Scientific 100° Series 25mm Waterproof Eyepiece delivers comfort, quality, and exceptional value for astronomers seeking an extraordinary viewing adventure.

Get ready to be captivated by the cosmos like never before.



  • 100° Apparent Field of View: Experience an extraordinary 100-degree apparent field of view, providing observers with a panoramic visual feast while promoting eye relaxation. This enables astronomers to focus on subtle celestial details for extended, discomfort-free stargazing sessions.
  • 25mm Focal Length: Striking a balance between magnification and field of view, this eyepiece's 25mm focal length offers versatile viewing suitable for a wide range of celestial observations. Ideal for detailed lunar and planetary study as well as deep-sky exploration.
  • Argon-Purged Waterproof Design: Each eyepiece is internally sealed and purged with inert, dry argon gas, ensuring waterproof performance. This innovative design safeguards against moisture and fogging, enhancing durability and extending the life of internal coatings.
  • Rigorous Water Testing: Thoroughly tested by submerging in water up to one meter for 30 minutes, guaranteeing waterproof capabilities even in damp or humid observing environments.
  • Fully Multi-Coated Optics: Multiple layers of anti-reflective coatings maximize light transmission while minimizing glare, reflections, and internal scattering. Resulting in exceptionally clear, bright views with enhanced contrast.
  • Edge-Blackened Optics: Enhancing image quality, the optical elements undergo edge-blackening, reducing internal reflections and stray light. This leads to increased contrast and improved image sharpness, ensuring celestial objects appear with exceptional clarity.
  • Precision-Machined Metal Construction: Meticulously crafted with precision-machined metal components, ensuring durability and longevity for years of stargazing adventures. The robust design maintains optical alignment for consistent performance.
  • Threaded Barrels: Accommodating filters, the threaded barrels enhance observations by adding various astronomy filters, allowing astronomers to customize their viewing experience for specific celestial targets and conditions.
  • Comfortable Eye Relief: Providing comfortable eye relief for observers wearing eyeglasses, allowing for relaxed and immersive viewing without the need to remove eyeglasses.
  • Wide Compatibility: Compatible with various telescope types and mounts, making it a versatile addition to any astronomer's equipment arsenal. Whether you have a refractor, reflector, or catadioptric telescope, this eyepiece delivers remarkable views of the cosmos.
