Explore Scientific 52 Degree Series 10mm Waterproof Eyepiece - EPWP5210-01

Discover the Explore Scientific 52° Series 10mm Waterproof Eyepiece. For amateur astronomers, the 10mm focal length is a pivotal addition to your collection.

It marks the transition from medium to higher power eyepieces, making it ideal for observing fainter deep sky objects lacking the brightness needed for higher magnifications.

The 52° Series 10mm Eyepiece are flat-field, multi-element oculars that redefine your visual astronomy experience. A Blend of Comfort, Quality, and Value.

Offering an expansive 52-degree apparent field of view, these eyepieces provide remarkable value without compromising quality, outperforming similarly priced Plossl eyepieces.

A significant advantage lies in their ability to enhance contrast and facilitate effortless observations, not by directly staring at an object but by slightly shifting your gaze to either side.

Known as averted vision, this technique proves invaluable when observing faint celestial objects.

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: Immerse yourself in an expansive 52-degree apparent field of view, capturing a broader celestial vista in a single glance. This immersive perspective enhances the observation of celestial objects, offering a rich and encompassing visual experience.
  • 10mm Focal Length: Striking a balance between versatility and detail, the 10mm focal length delivers an optimal level of magnification for a diverse range of astronomical observations. It provides a comfortable view of extended objects such as 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 fortified with EMD coatings, representing Enhanced Multi-Layer Deposition. This specialized coating process heightens light transmission and reduces internal reflections, resulting in images that are crisper, with higher contrast and enhanced color accuracy.
  • Waterproof - O-Ring Sealed Argon Gas Purged: Engineered to withstand the elements, this eyepiece features a robust waterproof design. It is fortified with O-ring seals, forming a secure, moisture-resistant barrier against water, dust, and debris. Additionally, it is charged with argon gas, further bolstering its resistance to internal fogging and moisture-related damage.
  • Rigorous Water Testing: Rigorously evaluated for waterproof proficiency, this eyepiece endured a 30-minute submersion under one meter of water without any performance degradation. This certification attests to its suitability for various weather conditions, including damp or rainy environments.
  • Removable Flip-Down Style Soft Silicone Rubber Eyecup: The eyepiece is equipped with a removable flip-down style soft silicone rubber eyecup. This eyecup provides comfort and effectively blocks out stray light, elevating the overall viewing experience. Furthermore, its removable design allows for customization based on the observer's preferences.
  • Edge Blackened: The eyepiece boasts edge-blackened optics, a process that darkens the edges of the lens to reduce internal reflections and enhance contrast. This refinement minimizes stray light, resulting in superior image quality, especially in situations with stark contrasts between bright and dark areas.
  • High-Quality Optics: Crafted with exacting precision, this eyepiece hosts top-tier optics designed to deliver exceptional views of celestial objects. The lenses meet stringent standards, with their optical surfaces polished to minimize aberrations and maximize light transmission.
  • Durable Construction: Purpose-built 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: Equipped with threaded barrels, this eyepiece enables users to attach standard astronomical filters. This functionality allows for the customization of the viewing experience, enabling the enhancement of specific colors or the reduction of light pollution in accordance with the observer's preferences and target object.
  • Comfortable Eye Relief: Offering comfortable 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.
