Thank you all for your kind advice. I'm considering buying a device on which to try driving Nexus DSC using the INDI protocols. Since I am a "noob" to Raspberry Pi, I'm strongly considering buying a Stellarmate dedicated device in order to start with a platform which I know is working out-of-the-box and then experimenting with adapting the configuration to my purpose.
Questions: I know Raspberry Pi 4 is in Beta for Stellarmate. How close is Raspberry Pi 4 / Stellarmate to stable for my use case? Any date for a (dedicated hardware )RPi4 / Stellarmate release? I see online some folks are getting tremendous performance boosts by booting from an SSD attached through USB3. Anyone have experience with that approach?
