You have to find true south, then use azimuth to rotate to the correct position
I use my solar noon shadow method to find true south and mark a permanent line
Works really well , anywhere
Used it at 4 different locations

PS: Prior to using the solar noon shadow method , I did use a quality Silva compass with magnetic declination and a long flat strip of aluminium mounted on top of the tripod and found to many variations in readings for true south at my different sites. Im assuming the magnetic was affected by the surrounding compositions of mineral or ore deposits in the substrate or subsoil
The one good thing about the solar noon shadow method, the Sun doesn’t lie , it’s accurate wherever you decide to plonk your mount down ( unless your in the Antarctic or on the equator)
