The Bresser's 70°-Series 15mm Eyepiece provides users with an easy and affordable upgrade to standard 1.25" diameter barrel Plossl eyepieces. Its 70 apparent field of view gives users a broad view of the sky while the five-element lens configuration and anti-reflection fully multicoated optics maximize light transmission to ensure the brightest possible images with minimal distortion across the entire field of view. A fold-down rubber eyecup prevents stray light from leaking into your eye's peripheral vision, a textured collar provides a non-slip grip when handling it, and a double-tapered barrel enables smooth insertion and removal from the focuser.
