Hi. I'll have a go at this since I am a happy SA and Kstars user.

it seems from this page

www.indilib.org/individuals/devices/telescopes/skywatcher.html

that the non-2i SA does not support goto. Just try if the driver labelled wifi works, if not go for the one which is actually a simulator (last item in table in the link above). In that case you just have to rotate by hand. At the very least you can supply the mount with power via usb.

Wherher or not you can get Ekos to rotate the RA, polar alignment is a dream with this setup. I never use the polar scope. i first do a rough PA around polaris, then a second one (or 2,3,4 attempts until I am happy) once I am in focus and on target. It works well to polar align other parts of the sky. I rotate in the direction that is most convenient and never think about the meridian with this mount. Just make sure that scope and cables are in a reasonable place so I can image for hours after without snagging or crashing

Camera: try the canon dslr driver. hopefully works without installing anything else than Kstars.

you can also use plate solving with this setup(actually required for PA to work) This works very well and convenient for example if you need to be accurate when combining images from multiple sessions. but it takes some setting up. Get the right astrometry files downloaded, correct sensor size and focal length etc. It is pretty well documented and there are many 'mouse-over' tips within Ekos. Sometimes the mount reports dec of 0 which can trip up the plate solving, most common fix for me when it fails is to Right click in the Kstars planetarium roughly where scope is pointing and click sync.

Hope you can get this to work.
Cheers
Hnastro
