I recently purchased a Raspberry PI 4 and installed the Astroberry operating system with a collection of astrophotography imaging tools installed that make it possible to use a low-power Raspberry Pi computer at a properly configured telescope, either in the field or in a observatory.
The software provides a ready platform for controlling your telescope mount, cameras and peripherals using the INDI software to connect the hardware to the associated software packages that come with Astroberry.
The Astroberry software can be downloaded from: https://www.astroberry.io.
This video provides a good introduction to interested folks who want to try Astroberry and integrate it into their observatory and astrophotography rigs.
