Hello All,
I am trying to accomplish what appears to be a similariler rig as what was achieved by Avocette. I currently have a RPi4 4Gb with a powered USB3 4 port mini hub which is powered by the Celestron battery unit. The hub is connected to the USB port of the headless RPi4. My new ZWO ASI120MC-S camera connects via USB3 to the hub. Also, my Celestron NexStar mount connects via USB2 to the hub. Since the mount gets its power from a Celestron battery unit, it should not put a load on the hub. The only device that may put a load on the hub is the camera. Based on this configuration, should I be able to power the RPi4 from a 10KmAh/5V battery pack?
