Explore Scientific 52° LER Eyepiece 3mm Ar

1. Long Eye Relief (LER): This eyepiece features a generous eye relief, providing a comfortable viewing experience, particularly beneficial for observers wearing spectacles. It allows for sustained observation without eye strain.

2. Argon-Purged Design: The optical elements are housed in an Argon-purged and sealed body. This prevents internal fogging, protects against moisture ingress, and ensures the lenses remain free from dust and fungal growth, preserving optical performance over time.

3. 52° Apparent Field of View: With a 52-degree apparent field of view, the eyepiece delivers a wide, immersive observation experience, making it easier to locate and track celestial objects while providing a broad perspective.

4. Advanced Optical Coatings: Each optical surface is fully multi-coated, enhancing light transmission across the visible spectrum. This results in brighter, higher-contrast images with excellent color fidelity and minimal internal reflections.

ABOUT THE EXPLORE SCIENTIFIC 52° LER EYEPIECE 3MM AR

The Explore Scientific 52° LER Eyepiece with a 3mm focal length offers a unique combination of performance and comfort for serious amateur astronomers. Unlike standard eyepieces, its Long Eye Relief (LER) design provides a generous distance between the eye and the lens, making observations significantly more comfortable, especially for eyeglass wearers. The 52° apparent field of view delivers crisp, high-contrast images of celestial objects, from planetary details to lunar craters. The innovative Argon purging prevents internal fogging and moisture ingress, ensuring the optical elements remain pristine and free from environmental degradation over time. This meticulous construction contributes to its mechanical precision and long-term reliability. Intended for deep-sky observation and high-magnification planetary viewing, this eyepiece excels in revealing fine details. The use of original Explore Scientific accessories and spare parts is highly recommended to prolong the lifetime and maintain the optical performance of this product.
