You can easily add a second auxiliary port to your Celestron mount with the Celestron AUX Port Splitter. This parallel adapter plugs into the AUX or hand controller port of your computerized telescope and splits it into two, allowing you to connect the Celestron StarSense AutoAlign, or another peripheral device, to your telescope and still keep the hand controller plugged in. Please note: This cable is compatible only with CG-5 mounts
