The solar noon shadow method of finding true south has worked extremely well for me at my 2 sites
After the first 2 star alignment I’m usually down to around 15 to 20 arc minutes straight off the bat from plonking the tripod down, levelling, setting home position and balancing.
After 2 or 3 iterations I’m down to less than 15 arc sec , my best has been 2 arc sec error
Initially I tried the compass magnetic declination method when I first bought the mount and I was way out all the time so I ditched the compass ( good quality Silver compass for mountaineering )
Can’t beat the good ol sun , never lets me down
Cheers
