Quick question, why the spacers in the last image? Why not have the piece of timber flat against the top of the tripod?
I'm having trouble finding a straight piece out here too, I wonder if aluminium would work...

The POM is not an absolute reference; it is calibrated relative to the position of my Takahashi EM200 and tripod in our back garden, so when I travel to another site, using the POM I will be able to set up the tripod in daylight to within ±1º of the SCP in azimuth.
Future enhancements may include a bubble level to set the altitude accurately as well.
