When setting up a Celestron 8SE telescope with the StarSense Auto Align V1 (model 94005), it is important to connect it to the correct port. Based on available information, the StarSense should be plugged into the AUX port rather than the one labeled “Auto guide,” as using the latter could potentially damage the unit due to differences in wiring. However, the AUX port is currently occupied by the included Celestron WiFi module, leaving no available port for the StarSense. This raises the question of whether the Auto Guide port can safely be used instead or if an alternative connection method is required.
