Hello Grant,
You might want to look at Solar Eclipse Workbench: https://github.com/AstroWimSara/SolarEclipseWorkbench I haven’t used it myself but the underlying control software is gPhoto2 which I have used to good effect via a PERL script running on a Raspberry Pi. I can also fire my camera (Canon 70D) via an interface from the Pi to the remote shutter release socket.
