Perfect for sweeping the night sky in comfort, the Explore Scientific 40mm 62° Series Eyepiece is engineered for deep-sky enthusiasts seeking maximum field coverage and relaxed viewing. As the longest focal length in the 62° line, it delivers breathtaking panoramic views of wide star fields, open clusters, and sprawling nebulae, all while offering extended eye relief that eyeglass wearers will appreciate.
Its 2-inch barrel supports the full 62° apparent field of view with zero vignetting, and the flat-field optical design ensures pinpoint sharpness across the entire image. Premium low-dispersion, high-index glass, EMD coatings, and edge-blackened elements work together to maximize contrast and reduce glare, helping you detect faint celestial details with ease—especially using averted vision.
The argon-purged, waterproof housing is sealed and submersion-tested to 1 meter for 30 minutes, providing long-term protection against fogging and environmental contaminants. Built for rugged field use with a flip-down rubber eyecup and durable, laser-engraved construction, this eyepiece is a reliable performer in any observing condition.
