iOptron's Super View 68° 30mm Eyepiece features a large 2" diameter barrel to fit into larger focusers and accessories. The long focal length produces a moderate to low magnification on most OTAs, providing a wide 68° apparent angle of view and a long 22mm eye relief to present you with an immersive and seemingly panoramic viewing experience of the night skies. This experience is further refined with fully multi-coated optics and blackened lens elements, which maximize light transmission and limit internal light diffraction to ensure bright and clear views with accurate color and improved contrast. Its housing is made of a lightweight and durable aluminum alloy, with a textured rubber collar to provide sure handling even in cold weather or while wearing gloves, and a fold-down rubber eyecup for comfortable use with or without eyeglasses.
