Upgrading your telescope eyepieces is one of the most effective ways to improve sharpness, contrast and field of view, and this collection makes it easier to do for less. Browse current savings on Explore Scientific waterproof eyepieces, including popular wide-field and ultra-wide designs loved by visual astronomers.
Our eyepieces are designed with multi-coated optics and, in many series, waterproof and gas-purged construction to resist fogging and dust during long observing sessions. Whether you need a high-power eyepiece for the Moon and planets, a wide-field eyepiece for star clusters and nebulae, or long eye relief for comfortable viewing with glasses, these eyepiece deals are a great opportunity to build out your eyepiece case. Availability and pricing can change quickly, so check back often for the latest offers.
When shopping eyepiece deals, consider the focal lengths you are missing. Most observers benefit from a low-power eyepiece for finding objects, a medium-power eyepiece for galaxies and clusters, and a high-power eyepiece for the Moon and planets. Check whether your telescope accepts 1.25-inch or 2-inch eyepieces, and consider long eye relief if you observe with glasses. Explore Scientific eyepieces are compatible with refractors, Newtonian reflectors, Dobsonians and Maksutov-Cassegrain telescopes, making a sale an ideal time to fill gaps in your collection.
