The JMI Telescopes Piggyback Camera Mount allows you to attach any camera to the outside of your telescope. This can be done with altazimuth-mount scopes for shorter exposures of up to about 7 minutes, but for sharp pictures free of star drift that go beyond that time you'll need a properly aligned equatorial-mount telescope.
This version wraps around the optical tube assembly and works with Celestron's earlier C5 scopes with dual fork arms, C5/C5+ scopes with a single fork arm, C5-S, C5-SGT, CG-5, G-5, and NexStar 5/5i. It does not work with the NexStar 5SE; for that scope, instead choose JMI's "BRKTPIG6".
