Explore Scientific 68° Series 28mm Waterproof Eyepiece

Explore Scientific 68 Degree Series 28mm Waterproof Eyepiece - EPWP6828-01

Discover the Explore Scientific 68° Series 28mm Waterproof Eyepiece.

Crafted through advanced computer design and utilizing a blend of low dispersion and high refractive index optical glasses, coupled with robust multilayer deposition coatings.

This eyepiece from the Explore Scientific 68° Series 28mm is Argon-Purged and Waterproof, finely tuned to deliver outstanding contrast, resolution, and a pristine flat field.

Immerse yourself in a complete visual experience with their expansive 68° apparent field and generous eye relief.

The eyepiece maintain focus across varying focal lengths and feature a removable, foldable soft silicone rubber eyecup for added comfort during extended observations.

To safeguard the internal components, the eyepiece body is meticulously Argon-purged, ensuring they stay as immaculate as the day they were assembled.

Argon's larger atomic size, in contrast to Nitrogen, provides a more secure seal, reducing the risk of leakage and diffusion over time.

Its inert nature inhibits undesirable reactions with eyepiece components, extending their lifespan, and shields against chemical interactions with potential contaminants.

Moreover, Argon's lower thermal conductivity ensures a slower absorption of heat, buffering against rapid temperature changes in the optics.

This sealed environment effectively prevents internal fogging and the growth of contaminants like fungus between lens elements.

Cleaning is a breeze, without the risk of cleaning solution seeping between elements.

To ensure an impeccable seal, each eyepiece undergoes rigorous testing in one meter of water for 30 minutes.

Elevate your stargazing experience with the Explore Scientific 68° Series 28mm Waterproof Eyepiece.

Features:

• 68° Field of View: Immerse yourself in the night sky with the expansive 68° apparent field of view offered by this eyepiece. Perfect for capturing panoramic views and observing large celestial objects, it provides a wide, immersive perspective of the celestial landscape.

• 28mm Focal Length: With its versatile 28mm focal length, this eyepiece caters to a broad range of celestial objects and astronomical observations. Its adaptability makes it well-suited for various astronomical pursuits.

• Advanced Optical Design: The eyepiece boasts cutting-edge computer-designed optics, incorporating a combination of low dispersion and high refractive index optical glasses. This results in exceptional image quality, minimizing chromatic aberration and enhancing color fidelity.

• Durable Multilayer Deposition Coatings: Equipped with robust multilayer deposition coatings, the eyepiece optimizes light transmission, reduces internal reflections, and enhances contrast. This ensures clear, crisp views of celestial wonders.

• Argon-Purged for Waterproofing: Establishing a sealed environment, the argon-purged eyepiece shields internal elements from environmental factors. This safeguard prevents fogging, even in damp conditions, ensuring continued clarity during observations.

• High Contrast and Resolution: Meticulously optimized, the eyepiece delivers high contrast and resolution, enabling detailed scrutiny of celestial objects. This proves invaluable for discerning fine details on the lunar surface, planets, and deep-sky entities.

• Superior Flat Field Characteristics: Designed to uphold exceptional flat field characteristics, stars remain sharp and pinpoint across the entire field of view. This attribute is especially valuable for astrophotography and detailed visual observations.

• Long Eye Relief: Offering generous eye relief, this eyepiece guarantees comfort during extended viewing sessions. This is particularly appreciated by eyeglass-wearing observers, allowing for extended viewing without excessive eye strain.

• Parfocal Design: The eyepiece maintains focus near the same point across different focal lengths. This parfocal design streamlines the observing process, facilitating seamless transitions between eyepieces without frequent refocusing.

• Soft Silicone Rubber Eyecup: Featuring a removable and foldable soft silicone rubber eyecup, this eyepiece enhances comfort during extended observations. It provides a cushioned interface between the observer's eye and the eyepiece, reducing fatigue.

• Argon vs. Nitrogen Purging: With its larger atom size, argon offers superior sealing properties, minimizing the risk of leakage over time. Additionally, its inert nature prevents adverse reactions with eyepiece components, extending the lifespan of internal elements.

• Resilience to Temperature Changes: Argon's lower thermal conductivity ensures slower heat absorption, 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 28mm 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.
