Hi,
I'm new to Astro Berry and astrophotography in general.
I have AB installed on a Pi4 with a EQ5 tracker and a simple 4" refractor scope.
To cut down on the number of wires etc. I want to use 2 x Pi3A's with HQ cams attached on the scope (1 for photos and 1 for the polar alignment).
I am struggling to find a way to connect the 3A's to my Pi4. I know i need to setup some form of camera streaming over IP from the 3A's to the 4, but am having problems trying to find a decent howto on setting up the HQ cameras and then connecting them to AB via IP.

Scope -> Pi3A(1) with HQ cam -> WiFi -> Pi4
Polar alignment -> Pi3A(2) with HQ cam -> WiFi -> Pi4

Any hints/tips or links to howtos would be great.

You might want to take a look at this: indilib.org/support/tutorials/159-indi-on-multiple-devices.html

Support for the HQ camera is in development and I'm not sure if using multiple HQ cameras is supported with that method.
