About Explore Scientific 52 Degree Series Eyepiece

Take your astronomical observations to new heights with the Explore Scientific 52 Degree Series 20mm Waterproof Eyepiece. Crafted with precision and durability, this high-quality eyepiece is designed to enhance your visual astronomy experience, offering a flat-field, multi-element design that delivers exceptional clarity and contrast.

With a generous 52-degree apparent field of view, this versatile eyepiece allows you to observe large celestial objects or vast landscapes with ease. Its wide-angle lens provides a broader perspective, transforming your stargazing sessions into immersive experiences.

One of the standout features of this rugged eyepiece is its waterproof construction. Whether you're observing the night sky amidst the dewy evening air or near a body of water, this eyepiece is built to withstand wet and humid conditions, ensuring uninterrupted viewing.

The Explore Scientific 52 Degree Series 20mm Waterproof Eyepiece also promotes the use of averted vision, a technique that involves gazing slightly to the side of your target object. This method utilizes the part of your eye that's more sensitive to light, enabling you to perceive fainter images with greater detail.

In comparison to a similarly priced Plossol, this eyepiece offers superior quality and value, making it an excellent choice for both amateur astronomers and seasoned stargazers. Experience the night sky like never before with the Explore Scientific 52 Degree Series 20mm Waterproof Eyepiece.
