Optimize your setup in such a way that it runs smoothly and according to your wishes even with a computer -aided telescope bracket of a third party (i.e. not from Celestron). This cable supplies the AUX connections on your Celestron Smart Devheater Controller with electricity. Put this AUX connection cable into one of the 12 V-DC power outputs of your controller and one of its AUX connections. When you switch on the controller, the cable delivers electricity to operate accessories via the other AUX connections of the controller, such as: B. the Skyportal WiFi module (for wireless PC connection) or the Celestron Focus Motor. Note: If you are already using a Celestron mount, you do not have to buy this AUX connection cable. The AUX cable connection to your bracket already supplies the AUX connections with electricity.
