Rated 5 out of 5

Superb Eyepiece

I?ve always wanted a 100 degree FOV eyepiece and I finally invested in the explore scientific 100 degree 20mm and 9mm eyepieces and my only regret is that I didn?t buy these sooner. The views are incredible. You can literally move your entire head up/down, left/right while looking through these eyepieces and it?s like looking out the window of a space shuttle?there?s essentially no noticeable field of view like you would see when using narrow FOV eyepieces. These eyepieces have taken my observing to new levels. I?d highly recommend the investment?you get what you pay for and these are worth every penny.

For the avid astronomer seeking an unparalleled stargazing experience, the Explore Scientific 9mm 100deg. Series Argon-Purged Waterproof Eyepiece stands out as a premium choice. Engineered with precision, this eyepiece incorporates a sophisticated blend of low dispersion and high refractive index optical glasses, alongside durable multilayer deposition coatings. The result is an eyepiece that delivers exceptional contrast, razor-sharp resolution, and a superior flat field that eliminates optical aberrations.

The expansive 100-degree apparent field of view of this eyepiece engulfs you in a truly immersive observation experience, akin to gazing out of a spacecraft window. With its generous long eye-relief, astronomers can comfortably observe celestial wonders for extended periods without eye strain. The eyepiece's design is further enhanced by a removable and foldable soft silicone rubber eyecup, which provides additional comfort and aids in blocking stray light.

Durability is also a key feature of the Explore Scientific 9mm eyepiece. It is argon-purged to prevent internal fogging and is waterproof, ensuring performance in all weather conditions. This makes it an ideal tool for astronomers who demand reliability and clarity, regardless of the environment.

Whether you're exploring the intricate details of the lunar surface, the swirling storms of Jupiter, or the majestic rings of Saturn, this eyepiece is designed to elevate your observational capabilities. Its wide-angle performance is especially beneficial for viewing expansive celestial phenomena, such as the sprawling arms of distant galaxies, the delicate filaments of nebulae, or the dense star fields of the Milky Way.

In summary, the Explore Scientific 9mm 100deg. Series Eyepiece is a high-quality, durable, and reliable accessory that offers innovative features and user-friendly design.
