The Explore Scientific 5.5mm 62° Series Eyepiece delivers razor-sharp high magnification in a compact, waterproof design—perfect for revealing intricate planetary features, lunar surface detail, and compact deep-sky objects like planetary nebulae and double stars. With a 62° apparent field of view and 12.9mm of eye relief, it offers an immersive experience that balances powerful performance with comfortable viewing.
Optimized for visual clarity, this eyepiece uses flat-field optics, edge-blackened lenses, and EMD (Enhanced Multi-Layer Deposition) coatings to enhance contrast, reduce glare, and preserve brightness—making it an excellent choice for averted vision techniques when hunting faint details.
Whether you're pushing magnification limits under stable skies or building a compact travel kit, the 5.5mm eyepiece combines optical excellence with durable construction, including a waterproof, argon-purged body that resists fog and contamination.
