Quote:Hello Kevin,For what it's worth, I have been using a 14" LX200 on that same wooden pier for almost eight years now. I removed the wooden wedge (still have it somewhere, I think) and modified the pier to accept an APT wedge.At this particular time I am not using a CCD camera, but the pier had nothing to do with ditching the camera (using a photoelectric photometer now - see an article I wrote here on CN recently). When I was imaging, the pier was never an issue. Wind was almost always the culprit, when elongated started showing up. Autoguiding took care of most of the other issues associated with long focal length imaging - which is just plain hard no matter what kind of equipment you're using. The pier is still hollow, I haven't seen the need to fill it with sand yet. As far as dampening time goes, well I try to avoid hitting the darn thing in the first place. It has always kind of bothered me that people go around thumping their scopes all the time. "Doctor ... it hurts when I do this!"Pat

Quote:The sticking point to a pier for me always comes down to the need to get 5 feet below the surface to avoid frost heaves.
Quote:If it weren't for you and Uncle Rod I would have not built that wonderful pier. I had just never thought that something as important as a pier could be built from wood.
