I too have dayglo orange fingernail polish marks on the driveway (now accented with Halloween glow in the dark paint, that I illuminate with my UV torch before set up). The tripod legs I leave in the levelled for position setting etc. If I then check the head alignment with my special made compass bar I find my greatest alignment error to be VERY small - almost always out in azimuth only
I have since moved to a new dark spot at home (but much more limited sphere), so a new alignment routine required. Doing a 3 star align is a cow there, but I persist
