Explore Scientific 68 Degree Series 34mm Waterproof Eyepiece - EPWP6834-01

Presenting the Explore Scientific 68° Series 34mm Waterproof Eyepiece.

Utilizing advanced computer design, a blend of low dispersion and high refractive index optical glasses, and robust multilayer deposition coatings, the Explore Scientific 68° Series 34mm Argon-Purged Waterproof eyepiece meticulously crafted for superior performance.

This eyepiece are optimized to deliver high contrast, exceptional resolution, and an impeccably flat field, providing an immersive viewing experience.

With a generous eye relief and a wide 68° apparent field of view, this eyepiece offer a full-immersion visual encounter.

Parfocal ensuring consistent focus across various focal lengths, and include a removable, foldable soft silicone rubber eyecup for observer comfort, recognizing the importance of eye comfort in pushing the boundaries of visual observation.

Designed to withstand the elements, the eyepiece body is Argon-purged, safeguarding the internal elements.

Argon, with its larger atomic size compared to Nitrogen, minimizes the risk of leakage and diffusion over time.

Its inert nature prevents unwanted chemical reactions, preserving the internal components and protecting against interactions with contaminants.

Additionally, Argon's lower thermal conductivity buffers against rapid temperature changes, maintaining stable optical performance.

The sealed, dry environment prevents internal fogging and the growth of contaminants like fungus between lens elements.

Cleaning is hassle-free, with no risk of cleaning solution seeping between elements.

To ensure a perfect seal, each eyepiece undergoes rigorous testing in one meter of water for 30 minutes, providing confidence in its waterproofing capabilities.

Explore Scientific 68° Series 34mm Waterproof Eyepiece combines optical excellence with durability for an elevated stargazing experience.



  • 68° Apparent Field of View: This eyepiece offers an expansive 68° apparent field of view, providing a wide and immersive perspective of the night sky. Its generous field of view is particularly advantageous for observing large celestial objects and capturing breathtaking panoramic views of celestial landscapes.
  • 34mm Focal Length: With a focal length of 34mm, this eyepiece provides a versatile viewing experience suitable for a wide range of celestial objects and astronomical observations.
  • Advanced Optical Design: Employing state-of-the-art computer design, the eyepiece integrates a combination of low dispersion and high refractive index optical glasses. This ensures exceptional image quality with minimized chromatic aberration and improved color fidelity.
  • Durable Multilayer Deposition Coatings: Equipped with robust multilayer deposition coatings, this eyepiece enhances light transmission, reduces internal reflections, and optimizes contrast, resulting in clear, crisp views.
  • Argon-Purged for Waterproofing: The eyepiece undergoes Argon purging, creating a sealed environment that effectively shields the internal elements from environmental factors. This ensures the eyepiece remains free from fogging, even in damp conditions.
  • High Contrast and Resolution: The eyepiece is meticulously optimized to deliver high contrast and resolution, enabling detailed observations of celestial objects. This is particularly crucial for discerning fine details on the lunar surface, planets, and deep-sky objects.
  • Superior Flat Field Characteristics: Designed to maintain excellent flat field characteristics, this eyepiece ensures that stars remain sharp and pinpoint across the entire field of view. This feature is invaluable for astrophotography and detailed visual observations.
  • Long Eye Relief: Offering generous eye relief, the eyepiece provides comfort for extended viewing sessions. This is especially appreciated by observers who wear eyeglasses, as it allows for comfortable viewing without excessive eye strain.
  • Parfocal Design: The eyepiece maintains focus at nearly the same point regardless of the selected focal length. This parfocal design streamlines the observing process, enabling smooth transitions between different eyepieces without the need for frequent refocusing.
  • Removable and Foldable Soft Silicone Rubber Eyecup: Including a removable and foldable soft silicone rubber eyecup, this eyepiece enhances comfort during extended observing sessions. This feature provides a cushioned interface between the observer's eye and the eyepiece, reducing fatigue.
  • Argon vs. Nitrogen Purging: Argon gas, being larger than Nitrogen atoms, offers enhanced sealing properties, minimizing the risk of leakage over time. Additionally, Argon's inert nature prevents adverse reactions with eyepiece components, thereby extending the lifespan of internal elements.
  • Resilience to Temperature Changes: Thanks to Argon's lower thermal conductivity, it absorbs heat at a slower rate, buffering against rapid temperature fluctuations. This feature helps maintain stable optical performance, even in environments with varying temperatures.
  • Rigorous Water Testing: Each eyepiece undergoes thorough testing in one meter of water for 30 minutes to ensure a perfect seal, providing added confidence in its waterproofing capabilities.
  • Included Accessories: Included in the Explore Scientific 68° Series 34mm 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.
