Very clever idea to use the sun to find true North.
And to keep a mark once you find it.
I have been thinking of building a slab on the alignment.
I also use a Lieca Disto measure inclinometer to find the lattitude angle as I can not see the pole. And a DSLR astrotracer GPS to get a rough North in the field.
After that it is drift alignment to fine tune. That is simple and always reliable.
