If you are planning on running the setup from a linux box, then you might want to consider a Celestron or iOptron mount, which have more mature support via INDI (which is the linux equivalent of ASCOM).
check out for supported devices:

Also suggest you have a look at Ekos, which works together with KStars to provide a front end for telescope and camera control, autoguiding etc
