The plate holder is compatible with attachment plates
of the standard thin type. It fits the bottom of a POLA-
RIE U and a Quick release angle plate also.
The mount head can be tilted freely between the
elevation of 0 degree to 90 degrees by loosening the
altitude clamp. It is possible to move the mount head
to the opposite side by 35 degrees over 90 degrees.
It allows you to finely move the mount head in the
altitude direction by turning the altitude fine adjust-
ment bolts.
Turning one side of the fine adjustment bolts will push
the mount head while loosening the other side of the
fine adjustment bolt. The fine adjustment range is
about +/- 7.5 degrees.
6) Camera Screw Socket
The PFA Unit DX comes equipped with the 3/8” to 1/4”
thread convert adapter and is therefore attached to
commercially available camera tripods with a 1/4” or
3/8” camera thread screw. Remove the covert screw
adapter with the supplied MS screwdriver if you use a
camera tripod with the 3/8” thread screw.
The camera tripod adapter on the bottom of the PFA
Unit DX can be exchanged for the supplied disc tripod
adapter that is compatible with Vixen’s tripods for
astronomical telescopes such as the APP-TL130,
ASG-CB90, and SXG-HAL130.
7) Altitude Clamp Presser Adjustment Screw
The torque of the altitude clamp lever is adjusted with
the supplied 2.5mm Allen wrench. Adjust the pressure
of the altitude clamp according to the size or weight of
the equipment installed on it.
4) Azimuth Clamp Lever
5) Azimuth Fine Adjustment Bolts
The mount head can be turned freely 360 degrees in
the azimuth direction by loosening the azimuth clamp.
Use the azimuth fine adjustment bolts to move the
mount head in the azimuth direction. Turning one side
of the fine adjustment bolt, push the pan mount head
while loosening the other side of the fine adjustment
bolt. The fie adjustable range is about +/- 7.5
degrees.

Attaching the Polar Fine Adjustment Unit DX to a Vixen’s tripod
Azimuth Bolts
Setting Up
The POLARIE U star tracker is shown here by way of
example.
3) Bring the POLARIE U star tracker over the plate
holder and attach it to the plate holder.
4) Make sure that the attachment base of the POLARIE
U and the plate holder fits snugly. Then, tighten the
lock screw securely.
The fine adjustment bolts are used for polar alignment in
your setup of the POLARIE U.
A pair of the altitude fine adjustment bolts is to adjust
the elevation of the polar axis to be parallel to the
Earth’s axis.
A pair of the azimuth fine adjustment bolts is to adjust
the direction of the polar axis to be angled to the Earth’s
axis.
Loosening one side of the adjustment bolt will allow you
to tighten the adjustment bolt on the other side to move
the mount head for fine adjustments.
1) Unfasten three socket head cap screws of the camera
tripod adapter on the bottom of the PFA Unit DX with
the supplied 2.5mm Allen wrench.
2) Take off the three socket head cap screws and
remove the camera tripod adapter from the PFA
Unit DX.
3) Replace with the disc tripod
adapter for the astronomical
telescope’s tripod.
4) Fasten the disc tripod adapter securely with the three
socket head cap screws that were taken off in step 2)
5) Now the PFA Unit DX becomes attachable to tripods
for Vixen’s astronomical telescopes. The APP-TL130
tripod shown by way of example.
Moving the Altitude and Azimuth Bolts Manually for Fine
Adjustments
Unfasten the two socket head cap screws on the plate
holder of the PFA Unit DX with the supplied 5mm Allen
wrench to remove the plate holder. The two socket head
cap screws are M8 screws placed at an interval of 35mm.
This allows for attaching the Dovetail-plate Mounting
Block sold separately. With the use of it, you will be able
to install a short optical tube such as the FL55SS
telescope on the PFA Unit DX.
