Explore Scientific 14mm 62° Series 1.25" Waterproof Eyepiece
The Explore Scientific 14mm 62° Series eyepiece is an excellent choice for amateur and seasoned astronomers looking for a balance of wide-field performance, contrast, and long-term durability—all in a lightweight and affordable 1.25" format. This eyepiece offers a moderately wide 62-degree apparent field of view, providing an immersive visual experience without the bulk and weight often associated with ultra-wide designs.
A Balanced Field for Deep Sky and Planetary Viewing
With a 14mm focal length, this eyepiece hits a sweet spot for a variety of telescopes and observing targets. In medium to long focal length scopes, it provides a magnification range well-suited for resolving lunar detail, teasing out planetary surface features, and framing smaller deep sky objects like globular clusters, planetary nebulae, and bright galaxies. It also makes for a great mid-power eyepiece in faster telescopes, giving users clean star fields and pleasing contrast.
62° Apparent Field: Wide Enough, Without the Distortion
While some eyepieces chase ultra-wide fields at the cost of edge performance, the 62° Series from Explore Scientific keeps things well-corrected. The 62° apparent field is wide enough to give that “spacewalk” feel, but still easy to take in without excessive eye movement. For many observers, especially those transitioning from Plössls or other narrow-field designs, this field of view is a significant and satisfying upgrade.
Fully Multi-Coated Optics and Excellent Contrast
The 14mm 62° eyepiece features fully multi-coated optics, optimized to enhance light transmission across the entire visible spectrum. These coatings reduce internal reflections and light scatter, helping to boost contrast—particularly important when observing faint nebulae or the subtle banding on Jupiter. The internal baffling and blackened lens edges further assist in suppressing stray light, keeping your views as sharp and clean as possible.
Argon-Purged Waterproof Construction
Explore Scientific sets itself apart with its patented waterproof eyepiece design. This 14mm eyepiece is sealed and purged with inert argon gas to prevent internal fogging, resist fungal growth, and protect the optics from moisture and environmental contaminants. Whether you’re observing in a humid climate or want to rinse the eyepiece after a dusty star party, the waterproof design gives you peace of mind and long-term reliability.
Comfortable Eye Relief and Fold-Down Rubber Eyecup
With approximately 15mm of eye relief, the Explore Scientific 14mm 62° is comfortable for most users, including those who wear glasses. The included rubber eyecup can be folded down if needed, allowing eyeglass wearers to access the full field of view without hassle. The 1.25" barrel is threaded for standard filters, allowing easy use of light pollution, planetary, or UHC filters to enhance your views.
Designed for the Field—Built to Last
Like all eyepieces in Explore Scientific’s lineup, the 14mm 62° Series is built to perform under real observing conditions. Whether you're using it on a fast Dobsonian, a compact refractor, or a longer focal length SCT, it delivers consistently high performance across a range of telescope designs. Its durable construction, sealed optics, and field-ready design make it a smart choice for observers who want gear that can keep up with them under the stars.
If you're looking for a high-performance eyepiece that offers an expansive field of view, clean optics, and rugged durability at a modest price point, the Explore Scientific 14mm 62° is a compelling option. It brings modern eyepiece engineering to the everyday observer—no compromise required.
