Allows attachment of camera to the 20mm weight shaft found on Vixen GP and Sphinx mounts. Because the Cameras weight is now helping counterbalance the Optical Tube, users are greatly appreciative of the fact they do not have to add MORE counterweights. Some use this to balance their Optical Tubes with Heavier cameras. Very multi-purpose.
