Telesco Workshop presents the PCBU-EQ2 mount head base set, a world-first design built specifically to unlock the full tracking potential of Vixen's Polarie U star tracker. Astrophotography rewards precision, and this original Japanese accessory brings smooth, wobble-free rotation and equatorial-style balance handling to your portable tracking setup.
The set includes the main PCBU-EQ2 base, a 1 kg weight, and two 100L weight shafts. The base itself weighs just 400 grams and houses two internal bearings for fluid, play-free movement. With the rotation unlocked, even a shaft weighing only a few dozen grams will swing freely, so you can fine-tune your balance with real precision.
Mounting gear is straightforward thanks to two 1/4-inch camera screws, while a custom stainless steel knurled screw locks ball heads firmly in place without slipping. Dialing in the right balance between camera and weights, much like on a full equatorial mount, eases the strain on the Polarie U's drive, sharpens tracking accuracy, and makes framing your shots far less fiddly.
This item is brand new and in stock. Please note that the Vixen Polarie U unit itself is not included; it appears in the photos only to show how the set attaches.

The 400 g PCBU-EQ2 unit incorporates two internal bearings for smooth rotation and a backlash-free construction. It has two 1/4-inch camera screw mounting points on the camera plate sections, plus a custom stainless-steel knurled screw and side tightening hole for securely mounting a ball head or similar accessory. Balancing camera equipment and counterweights reduces the load on the Polarie U and helps achieve greater tracking accuracy.
