Yeah thanks guys I'm all good for the true south alignment now.
So many different ways to calculate or observe true south.
Google tells me it's 1° 40' west of magnetic south here in Perth.
I'll have to compare that to my solar noon marked off of the hills hoist onto the fence.
Also, l stand well clear of metal objects when using my compass.
So for observational astronomy, once l dial in the first finder for the night l get myself lined up better and go from there.
