Hi Lars, The 8BitDo-N30 is a very small and light BT joystick that can be also wired via USB to the mount RPi server. I can control RA and DEC displacements, speed, park/unpark, mount stop. I can also control the focuser (in/out and motor stop). Actually, I mainly use it in visual mode. The main drawback of the BT operation is the auto off after few minutes that cannot be disabled.
