With its 66-degree apparent field of view, this 6mm Orion Expanse Telescope Eyepiece will definitely turn up the Wow! factor in your deep-sky observing experiences. Imagine taking in high magnification views of your favorite celestial objects with a wonderfully wide 66-degree view. With an Expanse 6mm eyepiece in your focuser, you can!

Expanse oculars have big eye lenses and great eye relief (13mm to 17mm). Eyeglass wearers can view the entire field without removing their glasses. All eyepiece elements are fully coated, with the outer lens multi-coated for additional light transmission. The 1.25" aluminum barrel is threaded for filters and internally blackened to eliminate internal scattering. And its fold-down rubber eyeguard enhances contrast by blocking stray light.
