I thought about using concrete as a pier but decided against it. I am sure I read on another thread that a concrete pier will have more flex than a metal one. ( Don't quote me on this, I might have it backwards). I am sure there would be someone here that can clarify this.
As far as vibrations go, filling the pier with some sort of dampening material might work. I am not sure if this needs to be done or not. I will have to wait till I get the mount and the telescope setup and trial it.

I watched a video on vibration and myths associated with some mounts especially DIY that there are a few features that create more vibration than concrete or simply proper construction. Mind you this is an issue with some high end mounts and hard for me know if this is relevant if you use a low cost (EQ5/EQ6) mounts.
I for the life of me can't find the video as usual, but it uses simple holes in the base for mounting not elongated. Fins travelling from the bottom to the top and vary for form and cut off triangle (to prevent single resonance). and also does not use extended bolts for the mount cap (again resonance). Maybe someone else can find it.
The video was shown by an mount designer (can't remember the name) but mentioned in the video he knew that he was not going to worry about the DIY market which is the primary reason for creating the video.
