Star guide!Developed primarily for use in prime focus deep-sky imaging or astrophotography with Schmidt-Cassegrain telescopes Celestron's Radial Guider is compact and sleek in design. It allows you to photograph and guide through the optical tube assembly of your telescope simultaneously ensuring the highest-quality images. It virtually eliminates differential flexure too because guiding and photographing both take place through the telescope.The radial guider is compatible with Celestron's C5 C8 C9¼ C11 and C14 telescopes and comes with a unique prism-angle adjustment screw. It must be used with a guiding eyepiece camera T-Ring and drive corrector (dual axis preferred). It's primarily for use with catadioptric telescopes but it also works on refractor telescopes having adequate back focus.Celestron's radial guider is a tremendous improvement over conventional off-axis guilders. Not only does it enable you to vary the angle of the prism but it maintains a fixed camera orientation while offering users the freedom to move the guiding eyepiece radially about 135 degrees.The Celestron radial guider is a must-have accessory for all astrophotographers and imagers!Shoot the planets with the Celestron NexImage Solar System Imager
