2" Barrel

Two-inch telescope eyepieces open up the widest true fields of view your telescope can deliver. The larger barrel allows for bigger field stops, which means low-power eyepieces in this size can frame large nebulae, open clusters, the Andromeda Galaxy and long stretches of the Milky Way in a single view. Explore Scientific's 2-inch eyepieces are designed for telescopes equipped with 2-inch focusers and diagonals, including many refractors, Newtonians and Dobsonians.

Our 2-inch eyepieces feature waterproof, gas-purged construction and multi-coated optics for bright, high-contrast views and dependable performance in dew and changing temperatures. Ultra-wide designs from our 82°, 92° and 100° Series deliver an immersive viewing experience, while long-focal-length options serve as ideal finder or sweeping eyepieces. If you want to get the most out of your telescope's aperture and enjoy truly panoramic views of the night sky, a quality 2-inch wide-field eyepiece is one of the best upgrades you can make.

Before choosing a 2-inch eyepiece, make sure your telescope has a 2-inch focuser or a 2-inch diagonal, and consider the eyepiece's weight and balance on your mount. Many observers pair one low-power 2-inch eyepiece for wide views with a set of 1.25-inch eyepieces for higher magnification, using a 2-inch diagonal with a 1.25-inch adapter to switch easily between them. On fast Newtonian reflectors and Dobsonians, adding a coma corrector sharpens stars toward the edge of the wide field. Explore Scientific's 2-inch eyepieces are a proven way to get the most dramatic deep-sky views from any capable telescope.
