Explore Scientific 100 Degree Series 9mm Waterproof Eyepiece - EPWP1009-01

Introducing the Explore Scientific 100° Series 9mm Waterproof Eyepiece, a remarkable addition to the world of ultra-wide eyepiece that will revolutionize your celestial exploration.

This hyper-wide class ocular redefine the boundaries of visual astronomy, offering an immersive experience like no other.

When you peer through a 100° Series eyepiece, you'll be astonished by the vast expanse of velvety black sky that stretches 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.

The apparent field of view of the 100° Series 9mm eyepiece approaches the upper limit for hyper-wide eyepiece design, making object location a breeze.

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

Furthermore, this hyper-wide eyepiece empower you with the ability 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 9mm Waterproof Eyepiece delivers comfort, quality, and exceptional value for astronomers seeking an extraordinary viewing adventure.

Prepare to be captivated by the cosmos like never before.



  • 100° Apparent Field of View: Boasts an extraordinary 100-degree apparent field of view. This vast field not only provides observers with a panoramic visual experience but also promotes relaxation of the eye. This relaxation allows astronomers to concentrate on subtle celestial details for extended periods without discomfort, making it ideal for immersive and prolonged stargazing sessions.
  • 9mm Focal Length: With a 9mm focal length, this eyepiece offers a versatile magnification level suitable for a wide range of celestial observations. It strikes a balance between magnification and field of view, making it ideal for detailed lunar and planetary observations, as well as deep-sky exploration.
  • Argon-Purged Waterproof Design: Each eyepiece features an internally sealed and purged design with inert, dry argon gas. This innovative construction ensures that the eyepiece remains waterproof, preventing moisture or fogging from affecting the optical elements. This design not only enhances the eyepiece's durability but also prolongs the life of the internal coatings, preserving optical performance.
  • Rigorous Water Testing: To guarantee its waterproof capabilities, the eyepiece undergoes thorough testing by submerging it in water up to a depth of one meter for a duration of 30 minutes. This rigorous testing procedure assures users of the eyepiece's ability to withstand various environmental conditions, including damp or humid observing environments.
  • Fully Multi-Coated Optics: Multiple layers of anti-reflective coatings have been applied to each optical surface. These coatings 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: To further enhance image quality, the optical elements of the 100° Series eyepieces are edge-blackened. This process reduces internal reflections and stray light, resulting in increased contrast and improved image sharpness. The elimination of unwanted light artifacts ensures that celestial objects appear with exceptional clarity.
  • Precision-Machined Metal Construction: 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: Compatible with a variety of 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 can deliver remarkable views of the cosmos.
  • Included Accessories: Included in the Explore Scientific 100° Series 9mm Waterproof Eyepiece package are protective eyepiece caps, comfortable soft silicone rubber eyecups, a secure eyepiece pouch/case for storage, and a limited 1-year warranty for added peace of mind.
