The Explore Scientific 62° Argon-Purged Waterproof Eyepiece Series delivers high-quality telescope eyepieces for immersive, wide-field astronomical observing. With a 62° apparent field of view and fully multi-coated optics, these eyepieces provide bright, sharp images with excellent contrast, ideal for observing the Moon, planets, star clusters, nebulae, and other deep-sky objects.

Each eyepiece is argon-purged, waterproof, and O-ring sealed to resist moisture and internal fogging, ensuring consistent optical performance in varied observing conditions. The 1.25″ barrel size fits most standard telescope focusers, and the textured grip ensures secure handling during observations.

Available focal lengths range from 5.5 mm for high-power planetary viewing to 40 mm for expansive, low-power deep-sky views, making this series ideal for building a complete eyepiece set or selecting the perfect magnification for your telescope.
