"The wedge mount in the image above provides elevation on a horizontal axis and rotation on a vertical axis, it only requires those two planes of adjustment to align with Polaris.  The adjustment has to be very fine. Impossible with a conventional video head or even worse a ball head.  A large geared head would not be stable enough."
