Let’s Dive into Explore Scientific 30mm 100-Degree 3in Series Argon-Purged Waterproof Eyepiece
The Explore Scientific 30mm 100-Degree 3in Series Argon-Purged Waterproof Eyepiece promises a breathtaking, immersive stargazing experience. Boasting a massive 100-degree apparent field of view and a robust, waterproof design, this eyepiece aims to bring deep-sky objects to life with exceptional clarity and contrast. Explore Scientific has a reputation for quality optics at reasonable prices, but this eyepiece is a significant investment, raising the stakes for delivering on its promises.
My journey to this eyepiece began with a frustrating realization: my existing collection felt like looking through portholes. I craved a truly immersive view, something that would pull me into the cosmos rather than just showing it to me. I’d read about the 100-degree eyepieces and the “spacewalk” experience they offer, and I was determined to find one that could live up to the hype.
Unboxing the Explore Scientific eyepiece was a moment. The sheer size and weight (82.9oz/2353g) immediately conveyed a sense of quality and robustness. The finish was smooth and professional, and the overall impression was of a premium piece of optical equipment, instilling confidence in the product from the start.
I considered the Tele Vue 31mm Nagler Type 5 and the APM UFF 30mm 82-degree eyepiece. Ultimately, the Explore Scientific won me over with its combination of a wider field of view (100 degrees vs. 82) and its waterproof, argon-purged construction, which offered peace of mind against moisture and internal fogging. I was willing to gamble that this Explore Scientific eyepiece would provide a superior viewing experience.
My first impression was a mix of excitement and slight intimidation. The size was considerable, requiring a sturdy telescope and mount. I hoped the views would justify the physical demands and steep price.
Real-World Testing: Putting Explore Scientific 30mm 100-Degree 3in Series Argon-Purged Waterproof Eyepiece to the Test
First Use Experience
My first test was conducted at a dark sky site in the high desert of Nevada. The skies were clear, with excellent seeing conditions, making it ideal for testing the eyepiece’s light-gathering capabilities and wide field of view. The Explore Scientific eyepiece delivered an immediately noticeable improvement in image brightness and sharpness compared to my standard 2″ eyepieces.
The waterproof construction proved its worth when a light dew began to form. While others were scrambling to protect their eyepieces, I continued observing, confident that the Explore Scientific was sealed against moisture. The 19mm eye relief made for comfortable viewing, even with my eyeglasses on.
There was a slight learning curve associated with the ultra-wide field of view. I initially found myself getting “lost” in the vastness of the image, but quickly adjusted to scanning the field of view and appreciating the context of the celestial objects. The only issue encountered on the first night was a slight kidney-beaning effect, a common artifact in ultra-wide eyepieces, but this was minimized by careful eye placement.
Extended Use & Reliability
After several months of use across various locations and atmospheric conditions, the Explore Scientific eyepiece continues to impress. It has become my go-to eyepiece for observing large nebulae and star clusters. The vast field of view allows me to appreciate the full extent of these objects in a single glance.
The eyepiece has shown no signs of wear and tear. The anodized aluminum body is scratch-resistant, and the multi-coated lenses remain pristine. I’ve been careful to store it in a padded case when not in use, further contributing to its longevity.
Cleaning the eyepiece is simple, requiring only a microfiber cloth and a gentle lens cleaning solution. The sealed design prevents dust and moisture from entering the interior, reducing the need for frequent cleaning. Compared to my older eyepieces, the Explore Scientific eyepiece delivers noticeably sharper images, especially at the edges of the field of view. It has significantly enhanced my observing sessions.
