Product Details
GSO’s SuperView eyepieces are known for delivering wide-field clarity at an affordable cost, making them a favorite among astronomy hobbyists. With a generous 60° field of view, this 50mm model is ideal for deep-sky exploration and wide-sweeping views of the night sky.
These eyepieces are designed to minimize chromatic aberration and distortion while maintaining sharpness across the field. The 5-element lens design, fully multi-coated optics, and blackened edges work together to enhance brightness and contrast.
A fold-down rubber eyeguard improves comfort during extended viewing, and a textured rubber grip ensures secure handling. The eyepiece is threaded to accept standard 2-inch filters and comes with two protective end caps.
