Are you running a "client version" of KSTARS?
Read here (from INDI forum/website):
Ekos does all the heavy lifting and it is STRONGLY recommended to run it on a separate computer (laptop or workstation). Which is where the networking comes in: A Raspberry Pi runs INDI server, running all the drivers for your AP and "serving" them to Ekos. Ekos is typically run on a more powerful (than a Pi) remotely networked PC. Ekos is where you set up your AP session: target, plate solving, tracking, focusing, and of course imaging - and MUCH more. If you have the hardware, Ekos can probably run it. Ekos (which again, is built into the Kstars planetarium program) is the nerve center controlling all your gear.
