I use 4 adjustable feet as my driveway has a splaid slope , 3 adjustable feet don’t quite achieve perfect level
I also set my OTA in the home position pointing true north along its centre axis I have 2 small 5mm alignment holes in the driveway 3 metres apart which designate true north ( solar noon meridian line using shadow method and Stellarium solar noon time ) This is not a critical requirement but I do it anyway
You spend time and do all the prep work right and your Goto is really accurate with these Skywatcher Synscan Goto dobs. Once you manually slew and nail your first alignment star spot on ( I use an Orion 20mm 70deg illuminated retinal eyepiece ) and then select your second star , the scope ends up really close with just a minor tweak. After that your off and running all night with excellent goto and tracking
Cheers
