92° ED Series Telescope Eyepieces: Immersive Deep Sky Viewing

The Explore Scientific 92° ED Series combines an immersive 92-degree apparent field of view with extra-low dispersion (ED) glass for sharp, high-contrast and color-accurate images. Designed in a 2-inch barrel size, these eyepieces are ideal for telescopes with 2-inch focusers and diagonals, letting you frame large nebulae, galaxies and rich Milky Way star fields with breathtaking context.

ED glass helps control chromatic aberration so stars remain crisp across the wide field, while waterproof construction protects the optics against dew, fogging and dust during long observing sessions. The 92° ED Series is an excellent choice for Dobsonian telescopes, Newtonian reflectors and refractors where a wide, immersive view brings deep-sky objects to life. If you want the panoramic feel of an ultra-wide eyepiece with the clarity that ED glass provides, the 92° ED Series delivers premium performance for serious visual astronomers.

Because the 92° ED Series uses a 2-inch barrel and a large field stop, it is best suited to telescopes with 2-inch focusers or diagonals and mounts with enough capacity for larger eyepieces. On fast Newtonian reflectors and Dobsonians, a coma corrector helps keep stars pinpoint all the way to the edge of the immersive field. Observers often pair a 92° ED eyepiece for wide-field deep-sky viewing with 72° ED Series eyepieces for higher magnification, creating a matched set with consistent ED performance across every focal length.
