Great piece for the price, no regerts!

New to star gazing and watched a video on this piece and ordered it. Not disappointed! The piece is very sturdy and well constructed, nebule and galaxies are VERY cool, great for "sky surfing!"

The Explore Scientific 62 Degree Series 40mm Long Eye Relief Argon-Purged Waterproof Eyepiece epitomizes the fusion of comfort, quality, and value for the discerning astronomer. Crafted with precision, this high-quality eyepiece is a testament to durable and reliable astronomical gear, designed to elevate your stargazing adventures. Its expansive 62-degree apparent field of view offers a panoramic experience, immersing you in the vastness of the night sky, while the near parfocal design minimizes the need for focus adjustments when switching between eyepieces.

Innovative in its construction, this eyepiece boasts a flat-field multi-element design that ensures sharpness across the entire field, enhancing your view of celestial wonders. The user-friendly feature of long eye relief provides exceptional comfort, especially for observers who wear glasses, allowing them to enjoy extended viewing sessions without strain. The argon-purged interior prevents internal fogging, an essential quality for maintaining clear and crisp images even in damp or humid conditions.

The robust build of this eyepiece ensures it can withstand the rigors of frequent outdoor use, making it a durable companion for your telescope. Its waterproof nature not only protects it from the elements but also makes it a reliable choice for astronomers who demand equipment that can perform in various environments.

Moreover, the eyepiece's excellent contrast capabilities and ease of use enhance the technique of averted vision. This skill, crucial for spotting faint objects, is facilitated by the eyepiece's ability to project images onto the more light-sensitive regions of your eye, revealing the elusive beauty of nebulae and galaxies.

Whether you're a novice enjoying the thrill of "sky surfing" or an experienced observer seeking to delve deeper into the cosmos, the Explore Scientific 62 Degree Series 40mm Long Eye Relief Argon-Purged Waterproof Eyepiece is a stellar choice that promises to bring the universe closer to you, one starry night at a time.
