Why shutdown the homelab in the first place? Are you trying to save on power consumption?
The other idea I had was to use another lower power device spoofing the server’s Mac. But it seems like it would require an ethernet hub and those don’t really exist anymore.
It’s taking a video and doing aligning/stacking of the frames like you said. Not taking an actual long exposure in the sensor. Most photos on modern phone cameras in low light are done this way. There’s a cool paper by google on their algorithm.
