today i took the chance to buy a used Nexstar 4SE (my first scope).
IIndilib server and web-manager are already up and running on my rpi 3 with raspbian. i had to compile indilib and third-party libraries from sources, since there were mismatching package dependencies with the latest raspbian. I was using kstars/ekos on macos and the indi-server on the rpi with the simulators (ccd, eqmod, nexstar gps) in the past few weeks, to test the software and see how all the stuff works. It is very impressive what you guys have created here. Now i'm trying to figure out on how to connect my mount.
Is it possible to connect the mount through the AUX port on the base, without using the handcontroller? Which driver i need to use (celestron nexstar, celestron gps) ?
I'm also planing to buy a guiding camera. Since the nexstar 4/5 mount doesn't have st4 port, does the driver/mount sopport pulse command for auto guiding?
I don't know the bit about not connecting via the hand-controller. I have Celestron SE here (for testing) and it works fine (connected to RPI3 via hand controller). You can use pulse-guiding with the driver. It is only one driver (GPS or Nexstar are just aliases, it's the same driver).
