Explore Scientific 32mm 62° 2" Waterproof Eyepiece
If you're aiming to take full advantage of your telescope's 2" focuser for wide-field, low-power views, the Explore Scientific 32mm 62° Waterproof Eyepiece delivers beautifully. Designed for immersive deep-sky observing with excellent optical correction, this eyepiece brings expansive vistas and solid mechanical build quality together in a package that won’t empty your wallet.
Expansive 62° Apparent Field with True Wide-Field Views
The 62° apparent field of view gives you that wide-screen experience, offering noticeably more sky than standard Plössls or narrow-field designs. In a 32mm focal length, this eyepiece is a low-power powerhouse—excellent for large targets like the Veil Nebula, the Double Cluster, or simply sweeping the Milky Way.
Because it's a 2" eyepiece, you’re getting maximum true field of view possible in your scope without stepping into exotic ultra-wide territory or using focal reducers. It makes a perfect finder eyepiece, and a favorite for relaxing, wide-angle deep-sky observing.
Waterproof and Nitrogen-Purged for Durability
Like all of Explore Scientific’s eyepieces in this series, the 32mm 62° is fully waterproof and nitrogen-purged. That’s not just a nice bonus—it’s a serious feature for anyone observing in dewy conditions, humid climates, or who values long-term durability.
The internal optics are sealed against fogging and moisture, and you can safely clean the exterior without worrying about internal damage. This level of ruggedness is a rarity in eyepieces at this price point.
Fully Multi-Coated Optics with Crisp Contrast
All air-to-glass surfaces are fully multi-coated, helping deliver high light transmission and minimizing internal reflections. You’ll get bright, contrast-rich images with crisp star points and low scatter—ideal for deep sky, open clusters, and even lunar observing when paired with a good filter.
While optimized for visual performance in f/7 and slower scopes, it still performs admirably in faster instruments, with strong center sharpness and good off-axis correction. The field curvature and edge softness typical in wider 2" eyepieces are kept in check nicely for the class.
Sturdy Construction, Comfortable Eye Relief
The eyepiece body is all metal with a textured rubber grip, giving it a high-quality feel that’s also practical in cold or damp observing conditions. It features a twist-up rubber eyeguard for adjustable comfort, especially helpful when transitioning between eyeglasses and direct viewing.
With 22mm of eye relief, this eyepiece remains comfortable even during extended sessions, and it’s friendly for most eyeglass users.
Built for 2" Focusers—No Compromises
This is a true 2" eyepiece, so you’ll need a 2" diagonal or focuser to use it. But with that comes the benefit of a significantly wider true field of view compared to 1.25" eyepieces of similar focal length. It’s an excellent match for Dobsonians, large refractors, and SCTs with 2" visual backs.
It’s also threaded for 2" filters, so you can pair it with your favorite narrowband or broadband filters to enhance nebulae and dark-sky contrast.
Excellent Value in a True Wide-Field 2" Eyepiece
For visual astronomers who want expansive, low-power views in a rugged, reliable package, the Explore Scientific 32mm 62° 2" eyepiece delivers. Whether you’re using it as your primary deep-sky viewer or as a complement to a wider set, it offers premium features—like waterproofing and long eye relief—without a premium price tag.
