Explore Scientific 52 Degree Series 6.5mm Waterproof Eyepiece - EPWP5265-01

Introducing the Explore Scientific 52° Series 6.5mm Waterproof Eyepiece.

This mid-range, high-power eyepiece, such as the 6.5mm, plays a pivotal role in smoothly transitioning between magnifications to achieve the optimal view of celestial objects.

Observing at higher powers demands a convergence of factors: impeccable atmospheric conditions, precisely collimated telescope optics, proper acclimation of the telescope to ambient temperature, and considerations of the object's brightness and size.

While the challenges are significant, the rewards of experiencing razor-sharp views at high power are truly indelible.

The Explore Scientific 52° Series 6.5mm Eyepiece exemplify flat-field, multi-element optics that revolutionize your visual astronomy encounters.

Boasting a wide 52-degree apparent field of view, these eyepieces offer exceptional value without compromising quality, surpassing similarly priced Plossls in both comfort and value.

Moreover, these eyepieces excel in providing outstanding contrast and ease of observation, particularly when employing averted vision—a technique that involves subtly diverting your gaze from the object.

This skill proves invaluable when discerning faint celestial objects, as it directs the image to a more light-sensitive part of your eye, enabling the detection of even the faintest details.



  • 52° Apparent Field of View: Dive into a panoramic 52-degree apparent field of view, capturing an expansive celestial vista with a single glance. This immersive perspective enriches the observation of celestial objects, providing a comprehensive and visually stimulating experience.
  • 6.5mm Focal Length: Balancing versatility and precision, the 6.5mm focal length delivers an ideal level of magnification for a diverse range of astronomical observations. It affords a comfortable view of extended celestial objects like star clusters and galaxies, while also revealing intricate details of planets and lunar features.
  • EMD (Enhanced Multi-Layer Deposition): The Explore Scientific 52° Series Eyepiece is enhanced with EMD coatings, embodying Enhanced Multi-Layer Deposition. This specialized coating process elevates light transmission and diminishes internal reflections, resulting in crisper images with heightened contrast and enhanced color fidelity.
  • Waterproof - O-Ring Sealed Argon Gas Purged: Crafted to withstand the elements, this eyepiece features a robust waterproof design. It is fortified with O-ring seals, establishing a secure, moisture-resistant barrier against water, dust, and debris. Moreover, it is infused with argon gas, further reinforcing its resistance to internal fogging and moisture-related damage.
  • Rigorous Water Testing: Subjected to rigorous evaluation for waterproof proficiency, this eyepiece endured a 30-minute submersion under one meter of water without any compromise in performance. This certification affirms its suitability for various weather conditions, including damp or rainy environments.
  • Removable Flip-Down Style Soft Silicone Rubber Eyecup: Equipped with a detachable flip-down style soft silicone rubber eyecup, this eyepiece ensures comfort and effectively shields against stray light, elevating the overall viewing experience. Additionally, its removable design allows for customization based on the observer's preferences.
  • Edge Blackened: Boasting edge-blackened optics, this eyepiece undergoes a process that darkens the edges of the lens to reduce internal reflections and intensify contrast. This refinement minimizes stray light, resulting in superior image quality, especially in scenarios with pronounced contrasts between bright and dark areas.
  • High-Quality Optics: Meticulously crafted with precision, this eyepiece hosts top-tier optics engineered to deliver exceptional views of celestial objects. The lenses meet stringent standards, with their optical surfaces meticulously polished to minimize aberrations and maximize light transmission.
  • Durable Construction: Designed for resilience, this eyepiece embodies a robust construction capable of withstanding the rigors of outdoor use. Its sturdiness ensures it can endure transportation, handling, and exposure to diverse environmental conditions, all without compromising its optical performance.
  • Threaded Barrels for Filters: Furnished with threaded barrels, this eyepiece empowers users to affix standard astronomical filters. This functionality enables the customization of the viewing experience, allowing for the enhancement of specific colors or the reduction of light pollution in accordance with the observer's preferences and target object.
  • Comfortable Eye Relief: Providing ample eye relief, this eyepiece facilitates extended periods of observation without inducing eye strain. This feature is particularly valuable for eyeglass wearers, ensuring they can maintain a full field of view without the need to remove their glasses.
  • Included Accessories: The accessory ensemble accompanying the Explore Scientific 52° Series 6.5mm 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.
