There was a paper issued by a guy in the US about pier design.
As I recall its the diameter of the tube that is more important than the steel thickness. 250mm diameter tube is a lot more stable than thicker 165mm tube. So you want maximum diameter.
The usual design is a large pier/base that is heavy and supports the steel or concrete pier (as wide as possible) and then a levelling plate so you can get perfectly level mounting for your scope.
You want the pier isolated from the floor if you were planning to do a slab floor (I like pavers instead of slabs, less heat retention, no vibration transmission and easy to lay).
