72° ED Series Telescope Eyepieces: Wide Field and High Clarity Viewing

The Explore Scientific 72° ED Series pairs extra-low dispersion (ED) glass with a wide 72-degree apparent field of view, delivering sharp, high-contrast images with excellent color correction. ED glass helps minimize chromatic aberration, so stars stay crisp and planetary details such as Jupiter's cloud belts and Saturn's rings appear clean and true to color.

Available in a range of focal lengths in 1.25-inch and 2-inch barrel sizes, the 72° ED Series covers high-power lunar and planetary viewing through wide-field deep-sky observing. Each eyepiece is built with waterproof construction to resist fogging and dust, and its comfortable field makes it easy to take in the full view without straining. For observers who want premium optical performance and a generous field of view in one versatile eyepiece line, the 72° ED Series is an outstanding addition to any refractor, reflector or Dobsonian telescope.

The 72° ED Series is a strong choice for observers who split time between planetary and deep-sky observing and want one consistent eyepiece line that excels at both. Shorter focal lengths deliver crisp, color-accurate planetary detail, while the 25mm, 30mm and 40mm 2-inch versions provide wide, sweeping views of the Milky Way. They pair especially well with apochromatic ED refractors, where the combination of ED objective and ED eyepiece glass produces exceptionally clean images. As one of our newest eyepiece series, the 72° ED line represents Explore Scientific's latest optical design and coating advancements.
