Thanks Duncan, I haven't even been able to look through the scope yet while its on the new pier... however giving the pier a good wack only results in vibrations for less than a second as felt by my hand. I feel the weak point for vibration will be my cheap EQ head etc and not the pier.
ie: Even if my pier settles very quickly its possible other less rigid parts of my system will continue to wobble for a little longer. However this should be LOADS better than the tripod, and my main aim was faster, easier set up
Cheers,
Dave
