This zoom eyepiece is designed for astronomers who value both optical performance and comfort during extended viewing sessions. It features up to eight lens elements arranged in four groups, with all internal surfaces fully blackened to reduce internal reflections. The use of ED-glass, including Lanthanum elements, helps minimize chromatic aberration and ensures balanced light transmission. Additional lens elements are included to reduce the spherical aberration of the human eye, helping to prevent the "black-out" effect and providing a more stable image.
