Celestron 11 Pound counterweight for Celestron CGEM equatorial mount

This Celestron 11 pound counterweight lets you balance heavy accessory loads (such as a photoguide scope, accessory dovetail, mounting rings, and a camera) mounted on a Celestron telescope using a Celestron CGEM computerized go-to equatorial mount. It will also let you balance a heavy non-Celestron scope installed on the Celestron CGEM mount (which comes with only one 11 pound counterweight as standard equipment). A hand-tighten knob holds the counterweight in place on the mount's declination shaft. It also works with any mount having a 0.75" diameter couinterweight shaft. It will not work with the 1.25" counterweight shaft CGEM DX mount, which uses 22 pound counterweight #1742.
