It is a sturdy panhead for tripod which is used to install the POLARIE U on a camera tripod. When you desire an accurate polar alignment with the polar alignment scope PF-LII, you need to adjust the orientation of the POLARIE U as accurately as possible. The polar fine adjustment unit DX enables you to move the mounted POLARIE U little by little in the directions of up and down and side by side.
The quick-release clamp is on the top of the polar fine adjustment unit DX. It is designed to securely hold a quick release angle plate or attachment plate of the thin standard type. Attaching or removing the plate is convenient as you simply turn a single handle.
As the two M8 thread holes placed at an interval of 35mm is provided on the head, the quick-release clamp can be exchanged for the dovetail-plate mounting block sold separately. It allows for mounting a Vixen optical tube such as an FL55SS.
The detachable tripod adapter plate is provided on the bottom of the polar fine adjustment unit DX. The tripod adapter is compatible with either 1/4" and 3/8" thread screw and is attachable to commercially available camera tripods. Exchanging the tripod adapter with another type as supplied will fit on the tripod head of other Vixen tripods designed for astronomical telescopes.
The mounted camera is tilted from 0 degree (horizontal) to 90 degrees (vertical) freely by loosening the altitude clamp lever. The fine adjustments are available within the range of +/- 7.5 degrees. it is possible to turn the camera to downward as the panhead can be angled exceeding 90 degrees toward the opposite side.
Unfastening one side of the adjustment screw will allow fastening the screw on the other side to adjust the direction finely. The adjustment screws can be tightened using an Allen wrench to hold the POLARIE U and a camera tightly.
