Hi Leo
Thanks for posting
That was me, I put it together including procedures about 6 years ago now
The Sun never lies no matter where you are on the planet
Stellarium will give an accurate solar noon time when the Sun traverses past the meridian. You can also google it as well
Hint : The more accurate your set up and markings are the closer to the south meridian line you will be and hence closer to the SCP.
I use fine builders string for setting up the shadow stick plus an Accumaster digital level. A builders bubble level just can’t give you fine accuracy.
One important trick is to ensure your ground is fairly level otherwise you could be many degrees off.
Cheers
Martin
