I have recently upgraded my setup.

Gem 45
Edge 8HD
ZWO 294MC
ZWO 174MM Mini guide cam for Celestron OAG
Pegagus Ultimate PowerBox
RPi 4 with Stellarmate
Pegagsus Focus cube.
Dew Strips plus a heated dew shield when imaging.
Apple Airport express

All power from a single power supply providing power to the Ultimate PowerBox.
The RPi has a wired connection to an Airport Express.

I now run Kstars/ EKOS and Indi on the RPi. 

I can remove the losmandy plate on top of the scope and put it on my Esprit 100.
