More of a pier question new
      #5721880 - 03/09/13 09:41 AM

I've seen round piers and square piers bolted to monolithic blocks of concrete but what about a simple steel I-beam, sized to carry the load of mount and equipment. It could be sunk right into the wet concrete and leveled with minimal fuss. It would be brutally strong. Not sure about vibration. Has this been tried and discarded?

There is a cool review from years ago about the different materials you can use for a pier. What it comes out with is that the larger your diameter, the better it will dampen. So, you find most people go that route.

Honestly, I have a wood pier, and I get FWHM 2.0 in my images... There are a few examples around here of it.

Use what you got or what you know. Your telescope won't know the difference.

An I-beam sunk in concrete will be difficult to modify. (Other than to shorten by using a cutting torch. If you have welding skills then go for it! Steel piers can at least be removed and hauled off to a welding shop for making changes.
