Celestron’s Universal Piggyback Mount is a simple astronomical accessory that can help you produce stunning photographs of the night sky. It allows you to attach a DSLR camera and a lens (or CCD/CMOS camera and a lens with one or both having a tripod attachment) to any Celestron SCT/EdgeHD optical tube assembly and take advantage of the fact that your telescope has a dual-axis motor drive. When your telescope is running with the camera attached, you can take longer exposures without star trails, and capture details in objects that would have been impossible had your camera been attached to a photographic tripod or a telescope without a drive system.
Experiment with different camera lenses and subjects. Some photographers love to capture comets with a relatively long, fast lens, and the Milky Way, as well as a myriad combination of terrestrial and celestial scenes, are yours for the taking when you own a Celestron SCT, a piggyback mount, a DSLR camera, and a couple of lenses.
