Omegon® EQ-320 RA tracking motor
Thank you for choosing our “EQ-320” tracking motor for the right ascension axis.
Equatorial mounts are tracked in the right ascension axis (hour axis); this motor set can therefore
help you to comfortably observe the sky and gain your first experiences with astrophotography.
The tracking motor is connected to the worm shaft by means of a flexible shaft coupling instead of
the flexible shaft for the manual fine motion drive.
This is quickly done and the mount is ready for use in a minimum amount of time.
1. The parts of the motor set upgrade
Here you can see the different parts of the motor assembly.

1. Hand controller with connecting
cable;
2. Motor with mounting bracket and
flexible shaft coupling (pre-assembled);
3. Battery pack for 8 x AA 1.5V batteries
(batteries not included);
4. Connecting cable for connection of
the hand controller;
5. Connecting cable for connection to
the motor;
6. Allen key and hand controller bracket
for simple attachment to the tripod leg
(not illustrated).
1. First disconnect the flexible shaft (3, Fig. 2) from the shaft of the RA
worm gear drive by loosening the union nut (2, Fig. 2) and pulling off the
flexible shaft.
2. Pull out the small roll pin (4, Fig. 2) fitted through the worm shaft with
a small pair of pliers and remove the union nut as well.
3. Remove the two mounting screws (1, Fig. 2) from the housing of the
mount. Align the tracking motor with its mounting bracket with the
threaded holes of the mounting screws and at the same time push the
shaft coupling onto the shaft of the RA drive screw.

Figure 4
Align the tracking motor with its mounting bracket with the
threaded holes of the mounting screws and at the same time
push the shaft coupling onto the shaft of the RA drive screw.
First ensure that the clamping screws of the shaft coupling (1,
Fig. 3) are not protruding into the bore of the coupling.
4. Now screw the two mounting screws into the threaded
holes provided on the mount. Attention: Do not tighten the
mounting screws at this stage.
5. Clamp the flexible shaft coupling (1, Fig. 3) using the
clamping screws (2, Fig. 3) of the shaft coupling, then
carefully tighten the mounting screws.
6. Now connect the power supply to the motor set and your
mount is ready for use.
1. Remove the cover of the battery compartment and
place 8x AA 1.5V batteries into the respective slots.
Rechargeable batteries can also be used, although they
generally have a lower capacity than normal batteries.
2. Ensure that the flat contact side of the batteries, i.e.
the negative terminal, is facing towards the spiral
springs.
3. Alternatively, a mains power pack with at least 1.5A
and 12V and a matching plug can be used. Mains power
packs are available with a variety of plug adapters.
4. Connect the hand controller to the battery pack and
test the function by switching on the tracking system
from the battery pack.

The red LED (2) on the hand controller now lights up, indicating that the tracking motor is in
operation. It is now permanently in operation, and once attached to the mount it compensates for
the Earth's rotation.
3. Operation of the motor set, direction buttons and switching between north and south operation
If you are stargazing in the “Northern hemisphere", the N/S switch (2) must be in position “N” for
North. In the Southern hemisphere it should then be in position “S”.

NOTE
Align the equatorial mount as accurately as possible with the north celestial pole. The
less accurately the mount is aligned, the quicker your targets run out of the field of view
again.
NOTE
To reverse the direction, the N/S switch (3) must be turned to “S” in the Northern hemisphere and
to "N" in the Southern hemisphere. Once the object has been found and set, switch back to “N” or
“S”.
The permanent tracking speed is the “single
sidereal”.
With the Omegon motor set for the EQ-320 mount,
the motor speed can also be set to 4 further speeds,
2x, 4x, 8x and 16x sidereal. That considerably
simplifies the search for objects, as you can roughly
adjust the telescope to the position of the desired
object in the sky using the eyepiece in the telescope,
and then find the object or allow the telescope to
find the object using the speed buttons.
