So in researching a few things I came across a 2016 page with Thomas Jacquin’s original setup.

I also came across the Alaskan Astro YT video on his All-Sky Raspberry Pi. Interesting approach. I do like using the PoE Hat to get connectivity and power, which runs to a larger all-weather box that has the PoE power hub, etc. He also 3D printed his enclosure, which is cool.
