I use an EQDir cable and that works really well. And therefore I don't know very well how to use Ekos with the SynScan Legacy driver. To my best of knowledge no star align with the hand controller is needed. Just start up the mount, enter the site details (longitude, latitude, time, time zone) and then switch to PC Direct mode. That part is essential. Then you can start Ekos and Ekos will take care of the rest. Once again, this is to my best of knowledge so I may be wrong.

My setup is mobile, so I need to set it up every time I want to use it. This means that the polar alignment needs to be done every time as well. Once this is done, the goto usually is not very accurate. So I use the Align tab in Ekos to improve the pointing using plate solving. See
