The second version of iOptron's SkyTracker Ball Head is an independently-adjustable pan and tilt mounting platform for the SkyTracker Camera Mount. The included 2.25 x 1.5" quick release plate has a series of non-marking pads to protect the base of the SkyTracker from scratches, and the 1/4"-20 mounting screw has a foldable D-ring to secure the SkyTracker to the QR plate without tools. Redundant plate locks and a 1.5" aluminum ball provide this head with the features needed to help keep your rig from accidentally slipping off the mounting system.
