Now you can use your heavier astrophotography and imaging rigs on a Polarie Star Tracker camera mount with this Vixen Optics Heavy Loading Kit. This kit enables heavier payloads to be properly mounted and balanced for smooth vibration-free tracking over extended periods of time without overloading the motors and gears. It includes the Multi Mounting Block, Dovetail Slide Bar DD, Fine Adjustment Unit, Quick Release Angle Plate, and Panorama Clamp, plus a 1kg (2.2 lb) counterweight and a counterweight bar.
Vixen Optics Polarie Multi Mounting Block
The Vixen Optics Polarie Multi Mounting Block replaces the stock camera mounting block that shipped with your tracking unit to allow the use of Vixen-style dovetail bars and plates to increase its usability. When used with the optional Dovetail Slide Bar, Counterweight and bar, and a photo head a counterweight system is created that effectively doubles the payload capacity to about 14 pounds. The design of the mounting block permits the permanent installation of the optional PFL Polar Scope to make it easier to align the Polarie tracker during set up.
Vixen Optics Polarie Dovetail Slide Bar DD
Designed to properly balance heavy loads like large-format DSLR bodies with long telephoto lenses or OTAs on their Polarie tracking head, the Vixen Optics Polarie Dovetail Slide Bar DD fits onto their optional Multi Mounting Block saddle. Your gear fits on one end using your own camera head or the optional Quick Release Panorama Clamp, while the opposite side accepts the optional counterweight bar for proper balancing. To aid in precise balancing, the bar can be positioned anywhere in the saddle by simply loosening the dovetail clamps and sliding the bar as required. To conserve weight without sacrificing strength, the bar is made of a lightweight and strong aluminum alloy. Only the bar is offered here, all other accessories need to be obtained separately, including the primary Polarie tracking head, and all the optional gear attaches to the bar via 1/4"-20 mounts.
Vixen Optics Polar Fine Adjustment Unit
Purpose-built for the Polarie Star Tracker system, Vixen Optics' Polar Fine Adjustment Unit allows you to precisely align your Polarie for better tracking and sharper imaging. This unit mounts on any 1/4"-20 or 3/8"-16 tripod head, and the Polarie mounts onto the included 1/4"-20 quick release plate on top of it. With the unit in-place, you are able to make minute adjustments to the orientation of the Polarie's polar alignment, with one rotation of the thumb screws moving it 5.7 degrees and a total adjustment range of ±15 degrees. The Polar Fine Adjustment Unit has a payload capacity of 15.4 pounds, so it can easily handle the Polarie plus larger DSLR and lens systems.
Vixen Optics Polarie Quick Release Angle Plate
Designed to fit their Polarie Quick Release Panorama Clamp, the Vixen Optics Polarie Quick Release Angle Plate provides an easy and stable way to attach your camera or smaller OTA onto the tracking system counterbalance rig. Using this clamp-plate combination brings the camera body closer to the center of gravity while adding much more strength and stability versus conventional ball heads.
The plate has a standard 1/4"-20 mount for cameras and other optics with a clearance of 0.4-3.5" (1-9cm) from the mount to the angle. Both parts of the plate, the long main side and shorter perpendicular piece, have a dovetail to enable the camera to be mounted vertically or horizontally as the situation or user's preference requires.
Vixen Optics Polarie Quick Release Panorama Clamp
When used with the Dovetail Slide Bar and Quick Release Angle Plate, the Vixen Polarie Quick Release Panorama Clamp completes a support system to quickly and easily mount a DSLR or smaller OTA onto the tracking head. The clamp attaches to the end of the slide bar via a 1/4"-20 mount and accepts the QR plate using a simple dovetail.
Vixen Optics Supplementary Counterweight Bar
Use Vixen Optics' Supplementary Counterweight Bar to balance between a camera and their AP Photo Guider for more stable tracking. Your camera is attached on one side of the Dovetail Slide Bar PG, and this counterweight bar is attached on the other side to hold the optional counterweight.
