The 2" diameter barrel 120°-Series 9mm Eyepiece from Explore Scientific gives you an apparent field of view that goes beyond ultra-wide angle, but with a short focal length. This combination of AFoV and focal length produce expansive images of the night sky at high magnification. Objects stay in your field of view for extended periods, reducing the need for adjustments that can cause vibrations.

Anti-reflective multicoated optics ensures bright, high-contrast images with true color transmission across the entire hyper-wide field of view. The eyepiece features a textured surface for a sure-grip when changing it out, argon-filled body for water and fogproof performance when used in extreme temperatures and climates, and a double-tapered barrel for smooth insertion and removal from the focuser.
