Whilst there’s a break in the poor weather this week and the Sun is out , I set up my gnomon ( shadow stick ) to mark the True Celestial South Line on my deck before the Dome arrives soon
The front and centre 250mm dia concrete piers under the deck were almost spot on aligned with the true south line ( about 4mm offset ) pretty happy about that as I took so much time setting them up before the deck was built and if they were way off there’s nothing I could do about except pull the deck apart and start all over again. I can breath a bit easier now .....
