My observatory is soon to begin construction.... need to build the pier first, then an 1800x2400 roll off roof obs around it.
This is my design for the pier - I am going for a bolt down metal job for portability (relative portability I suppose!).
All steel will be 5mm thick, and will be galvanised after fabrication.
Any comments? - I am making the ribs very long as the pier is long, as I want it a metre off the obs floor for comfort, and since the obs will be on short posts it needs to be higher still.
What size plug of concrete do people think I should attach this thing to.... I was going to go about 600x600 by however deep I could get (600-750 or so).... should that be enough??
Ordered the pipe today!
