Vixen Polar Fine Adjustment Unit
The polar fine adjustment unit from Vixen not only permits a finer level of control over your Polarie Star Tracker, but also allows the Polarie to be attached to a normal tripod. It permits adjustment of ???????? 15 degrees to the polarie, and has counter-rotating thumb screws to make minute and precise adjustments. One full rotation of one of the thumb screws is a 5.7 degree adjustment. It will mount to a 1/4-20 or 3/8 inch tripod head, and it comes with the 3/8 inch adapter and a tool to change them. The top mounting is a quick release 1/4-20.
