Optimize your setup to run smoothly and the way you want—even with a third-party (i.e., non-Celestron) computerized telescope mount. This cable provides power to the AUX ports on your Celestron Smart DewHeater Controller. Plug this AUX port cable into one of your controller's 12V DC power outputs and one of its AUX ports. When you switch the controller on, the cable provides power to run accessories through the controller's other AUX port(s), such as the SkyPortal WiFi Module (for wireless PC connection) or the Celestron Focus Motor. Note: If you already use a Celestron mount, you do not need to purchase this AUX port cable. The AUX cable connection to your mount already provides power to the AUX ports.
