About Explore Scientific 92deg Argon-Purged 17mm Long Eye Relief Waterproof Eyepiece

Before you embark on your next stargazing adventure, consider the transformative experience offered by the Explore Scientific 92deg Series Argon-Purged 17mm Long Eye Relief Waterproof Eyepiece. This hyper-wide class ocular device is designed to redefine your visual astronomy experience with its ultra-wide eyepiece, offering unparalleled comfort, superior quality, and exceptional value.

The first time you peer through this 2" barrel eyepiece, you'll be astounded by the expansive, inky black sky that unfolds before you. The 92deg Series eyepiece is designed to make you feel as if there's nothing separating you from the vast universe. Its apparent field of view is near the maximum achievable for hyper-wide eyepiece designs, making celestial objects not only easier to locate but also remain in your field of view for extended periods. This feature is particularly beneficial for non-driven telescopes, as it minimizes the need for frequent adjustments.

One of the standout features of this 92deg Series Argon-Purged 17mm Long Eye Relief Waterproof Eyepiece is its facilitation of averted vision. This technique allows you to gaze slightly to the side of an object rather than directly at it, placing the image on a part of your eye that's more light-sensitive. This can significantly enhance your ability to observe faint objects in the night sky.

In addition, the eyepiece is argon-purged, ensuring waterproof performance and long-lasting durability. This makes it an ideal choice for astronomers who demand uncompromising quality and performance in all weather conditions. Experience the universe like never before with the Explore Scientific 92deg Series Argon-Purged 17mm Long Eye Relief Waterproof Eyepiece.
