Explore Scientific 82 Degree Series 14mm Waterproof Eyepiece - EPWP8214-01

Introducing the Explore Scientific 82° Series 14mm Waterproof Eyepiece.

This eyepiece offers a popular focal length in the upper-medium power magnification class, combining a super-wide apparent field with generous eye relief.

It excels in various applications, from observing globular star clusters to planetary nebulae and even the intricate cloud structures near the nuclei of comets.

Additionally, it enables initial observations of planets and, when paired with proper filtration, allows for the study of active regions on the sun.

Crafted with precision and using advanced computer design, this eyepiece employs a blend of low dispersion and high refractive index optical glasses, along with durable enhanced multilayer deposition coatings.

These features optimize contrast, resolution, and flat field characteristics, ensuring a superior viewing experience.

The 82° apparent field provides a full-immersion visual effect, promoting relaxation at the eyepiece and allowing for extended observation sessions.

This eyepiece also facilitates the use of averted vision, enhancing the perception of faint details across a wide field of view.

Meticulously assembled with precision machined metal lens barrels, each eyepiece maintains perfect optical alignment for years of rugged field use.

Explore Scientific 82° Series Waterproof Eyepiece

To minimize internal reflections, all internal surfaces and lens edges are coated in flat black.

Explore Scientific's 82° Series 14mm Waterproof eyepiece offer a combination of comfort, quality, and value, immersing observers in an ultra-wide field of view that enhances the overall observing experience.

With relaxed eyes, extended observation periods become effortless, and previously unnoticed details come into view.

Additionally, the eyepiece's design allows for easy off-center gazing, a technique known as averted vision, which proves invaluable when observing faint celestial objects.



  • 82° Apparent Field of View: The Explore Scientific 82° Series 14mm Waterproof Eyepiece boasts an impressively wide apparent field of view, providing observers with an expansive, immersive visual experience. This wide field of view is particularly advantageous for capturing large celestial objects and allows for sweeping views of the night sky in a single frame.
  • 14mm Focal Length: With a focal length of 14mm, this eyepiece strikes a balance between magnification and field of view. It is an excellent choice for observing a variety of celestial objects, including globular star clusters, planetary nebulae, and the intricate features near the cores of comets. This focal length also enables initial observations of planets and, with proper filtration, provides the opportunity to study active regions on the sun.
  • Advanced Optical Design: Employing cutting-edge computer design techniques, this eyepiece incorporates a combination of low dispersion and high refractive index optical glasses. This results in exceptional image quality with minimized chromatic aberration and improved color accuracy. Observers can expect clear, high-contrast views with true color representation.
  • Durable Multilayer Deposition Coatings: The eyepiece is equipped with robust multilayer deposition coatings. These coatings play a pivotal role in enhancing light transmission, reducing internal reflections, and optimizing contrast. The outcome is sharp, well-defined images with impressive clarity and detail.
  • Argon-Purged for Waterproofing: The eyepiece undergoes a rigorous Argon-purging process, creating a sealed environment that effectively protects the internal optical elements. This ensures the eyepiece remains free from internal fogging, even in damp or humid conditions. The use of Argon gas provides a superior seal, minimizing the risk of leakage and offering long-lasting waterproofing.
  • High Contrast and Resolution: The eyepiece is engineered to deliver high levels of contrast and resolution, making it an invaluable tool for detailed observations of celestial objects. This feature is crucial for discerning fine details on the lunar surface, planets, and deep-sky objects, providing observers with clear and distinct views.
  • Superior Flat Field Characteristics: Maintaining excellent flat field characteristics, this eyepiece ensures that stars remain sharp and pinpoint across the entire field of view. This characteristic is particularly valuable for astrophotography and detailed visual observations, allowing for accurate representations of celestial objects.
  • Long Eye Relief: The eyepiece offers generous eye relief, a feature that enhances comfort during extended viewing sessions. This is especially appreciated by observers who wear eyeglasses, as it allows for comfortable viewing without the need for excessive eye strain.
  • Parfocal Design: The eyepiece is engineered to maintain focus near the same point regardless of the focal length selected. This parfocal design streamlines the observing process, allowing for smooth transitions between different eyepieces without the need for frequent refocusing.
  • Removable and Foldable Soft Silicone Rubber Eyecup: The eyepiece includes a removable and foldable soft silicone rubber eyecup, which adds to the observer's comfort during extended periods of use. This feature provides a cushioned interface between the observer's eye and the eyepiece, reducing fatigue and enhancing the overall viewing experience.
  • Argon vs. Nitrogen Purging: Argon gas, with its larger atomic size compared to Nitrogen, 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: Argon's lower thermal conductivity ensures slower heat absorption, which helps buffer against rapid temperature fluctuations. This feature helps maintain stable optical performance, even in environments with varying temperatures.
  • Rigorous Water Testing: To guarantee impeccable waterproofing, each eyepiece undergoes thorough testing in one meter of water for 30 minutes. This stringent process provides added confidence in the eyepiece's ability to withstand varying environmental conditions and ensures its long-term reliability.
  • Included Accessories: The accessory ensemble accompanying the Explore Scientific 82° Series 14mm Waterproof Eyepiece includes protective eyepiece caps, comfortable soft silicone rubber eyecups, a secure eyepiece pouch/case for storage, and is complemented by a limited 1-year warranty, ensuring heightened peace of mind for users.

                                                              I was looking for another eyepiece for the telescope purchased for my grandson. But even though I am familiar with basic telescope equipment, I still had more questions. Through a series of quickly returned emails I was able to make an excellent choice which my grandson loves. Prompt service and quality materials at a fair price. I was very impressed with their personal service. Top notch!
