Hi-- I have a C14 on a Losmandy GM200 mount which sits on top of a Le Sueur 7" pier. The pier is attached to three large bolts suck into an 18" concrete cylinder in the ground. The botttom of the pier does not actually touch the concrete, but is bolted slightly above it using a pair of nuts...this is used for final leveling. I am noticing some vibration from my drive which was not present when I used a tripod. I'm trying to figure out if the vibration is coming from the 7" pier itself or the way it is bolted above the concrete. If its the pier, I may be able to damp the vibrations by filling the pier with sand or concrete without compromising the bolts and leveling nuts. Anybody else have any experience with this kind of thing ??
Thanks,
Dan
