  1. The large ball pivot in the center of the base plate of the DDM160 pier is difficult to align when mating the pier to the base plate. The female part of the pivot tends to lock in place at an angle. This prevents the pier from resting on the two cylindrical side supports which are welded to the base of the pier. Any tips on how to prevent this? Thanks, Robert W. Williams
  2. Hi all, I am now planning the construction of a permanent observatory near Madrid. I have preselected the DDM85 mount and I would like to share with you some doubts. - Which method do you used to interface the concrete pillar with the mount?. In some observatories I saw the typical 3 long screws embedded in the concrete to which an intermediate levelling plate (not provided) is attached and over this the DDM85 plate. I find this setup not satisfactory since is connecting your extremely well machined (and expensive) mount over something that can be affected by differential thermal expansions etc. - What do you think is the best way to interface this mount to the concrete pillar? - Is that crutial the leveling of the mount?. After all the polar axis in independently adjusted. - I am thinking about a 3.5 meter pillar of 40cm in diameter with 1x1x1 basement. Do you think is adequate? - Is there anybody using Linux to control de mount. Any plans to support it from ASA? Many thanks in advance, Pedro
