I have an INDI server with a SkyWatcher AZEQ6 mount connected that works perfectly with KStars, so the communication and the server is properly installed.
I am now trying to do some test with python to control the mount with the PyIndi library but I haven't succeed even in a simple slew script.
As far as I understood the following script should slew to Vega, but it doesn't do anything neither it returns any error.
What am I doing wrong?
