The new pier adapter rotates on a bearing surface for ultra-smooth operation. This allows you to lock the mount down with no need to loosen the base during azimuth adjustment. This option is especially recommended for use in the field. You may wish to purchase two or more of these assemblies to install on separate piers. Perhaps you have a permanent observatory and a portable pier for traveling to dark sky sites.
