Could be a lot of hard work and nothing but problems. I would be worried about the two seperate components moving in the ground. I opted for a concrete pier in my observatory. I dug a hole a lot larger and deeper than i required for the pier and filled it with concrete. Before the concrete set i pushed the pier cage into the concrete. Once the concrete set i placed the pier shutter over the rebar cage and concreted the pier. The result was an 12" diameter pier that is attached to an extremely large chunk of concrete. In two years there has been no movement of the pier yet. The pier is isolated from the observatory and it causes me hardly any vibration problems either. There are some plans of my pier design here: http://groups.yahoo.com/group/Roll_Off_Roof/files/Olympus%20Mons%20Observatory/Pier%20Dimensions/ Regards Stewart Waters -------------------- Meade LX200 GPS14" UHTC polar mounted in roll in roof observatory. http://tech.groups.yahoo.com/group/Roll_Off_Roof/ Post Extras       Entire thread Subject Posted by Posted on Building an observatory, links of interest.
