5.Adjusting the polar axis
Follow the instructions on the battery case to install the batteries
correctly, and insert the plug on the cable into the power socket
on the Skymemo RS. The LED on the tracker should turn on and
the motor should actuate.
Screw the reticle illuminator into the polar scope and insert the
plug on the cable into the reticle illuminator power socket on the
tracker. Fig.8
Turn the polar finder (focus adjustment) part of the polar scope
until the reticle pattern is clearly visible. The brightness of reticle
illumination can be adjusted by inserting a precision screwdriver
into the reticle illuminator intensity control in the tracker.
Move the tracker up/down and to the left/right to adjust the polar
axis. Fig.9 After the adjustment, tighten the clamps.
For details on how to adjust the polar axis, refer to the detailed
explanation on the page 8 and 9.
Remember to look into the polar scope before and after shooting
to confirm that the accurate polar alignment has been maintained.
The failure to do so may result in undesirable results.
You can use the above method to check the operation of the
tracker, but another way to check its operation is to put your ear to
the tracker and see if you can hear the motor sound.
6.Framing and Shooting
Hand controller
Normally with the Skymemo RS, it isn't necessary to touch the
unit upon shooting. However, if a guide telescope is used, insert a
hand controller plug into the hand controller socket on the tracker.
Stop and speed control is performed using the hand controller, but
half-speed is set with the half-speed operation selector switch on
the main panel.

Before
exposure
After
exposure
Loosen the RA attachment clamp and camera rotation clamps,
point to the target, and lock the clamps. To turn the view field, use
the rotation of a ball-head or the tripod mount ring attached to the
lens.
Also, remember not to use any setting that will change the
balance of the polar axis before and after the exposure, as shown
in the figure 10. Otherwise, shooting problems are likely to occur.
AF camera lenses and telephoto lenses using ED or fluoric are
not adjusted for infinity ( ). If any such lens is used, make
adjustments in advance using a fixed star, etc., found near the
shooting field.
Also note that, with an AF camera lens, even a very small force
can operate the focus ring. Accordingly, secure the ring using
tape, etc., before use.
