Vixen Optic's PG Mount Head Set is offered here to allow you to mount a camera, the AP Photo Guider, and AP Star Tracker on their Advanced Polaris. The set is comprised of three components:
1: The Dovetail Slide Bar PG which accepts the camera
2: The Mount Head Unit onto which the dovetail bar mounts
3: the Mount Head Base which accepts the head unit and is used to attach the head and dovetail onto the AP mount
All three pieces feature holes that allow the use of the AP Polar Alignment Scope for increased alignment accuracy and improved tracking capabilities, and the mount head unit employs a friction control system that allows you to simply move the unit to wherever you want it and release it without using cables or clutches.
Advanced Polaris Clamp Mount Head Unit
Vixen Optics' Advanced Polaris Clamp Mount Head Unit is designed to attach the dovetail slide bar or dovetail tube plate onto the AP mount. Its unique friction-control system allows users to move the OTA laterally by hand and it stays in position when released, and an included AP Clamp Lever securely fixes the scope at the desired position on the head. This AP Clamp Mount Head Unit is compatible with the AP Clamp Mount Head Unit, but not with the AP Photo Guider. The unit has a center hole for use with the polar alignment scope.
Dovetail Slide Bar PG
Attach your camera onto the Vixen Optics Dovetail Slide Bar PGA using one of the three 1/4"-20 bolts, then mount the bar on a compatible 44mm Vixen-style saddle. This bar was primarily designed for use with the Advanced Polaris Photo Guider and AP Star Tracker, but will fit other mounts and saddles. An elongated hole in the center of the bar allows the camera to be balanced around the optional polar alignment scope.
Mount Head Base for Advanced Polaris Mount
Vixen Optic's Mount Head Base is an adapter that connects the Manual Slow Motion Control Module or DEC Motor Module with their Advanced Polaris Mount Head Unit or the AP Polar Axis Bracket and the Time-Lapse Adapter.
