Seamless Magnification Control: A simple twist of the zoom housing adjusts focal length from 8mm-24mm; Ideal for planetary clusters, lunar details, and deep-sky nebulae observation
Extended Eye Relief for Eyeglass Users: 15 to 18 millimeter eye relief; The foldable rubber eye cups also eliminate any stray light; Whether you wear eyeglasses or not; you are guaranteed a good field of view at a comfortable viewing distance
Versatile for All Observers: Wide 40 degree to 60 degree apparent field of view adapts to planetary and deep-sky targets. Precision stepless zoom mechanism outperforms fixed focal length eyepieces
Utilizing the 2X Barlow Lens with a longer focal length eyepiece allows you to achieve the same high magnification while benefiting from a larger exit pupil; This configuration typically results in reduced eye strain and improved viewing comfort
Some telescopes will not focus properly without barlow to get infinity focus; Barlow lens will solve the problem; Allows connection of a SLR/DSLR or mirrorless camera to a telescope; works as a camera lens to capture images of the night time sky
