program/software to calculate the pole star position.
Press the power switch on the mount to turn the SkyGuider
polar scope cover in the back and polar axis cover in front. (If you are not using the DEC Mounting
Bracket, you have to remove the Camera Mounting Block and ball head to expose the polar
scope.) Look through the polar scope eyepiece. If you can not see red polar scope dial or a large tick
mark is not on top, release RA Clutch Disk slightly. Rotate the RA axis until you see the red LED
illumination and/or adjust one of the large tick mark to the top. Lock the RA axis. Adjust the eyepiece
to bring the reticle dial in focus.
Adjust the mount in altitude (using Latitude Adjustment Knob) and azimuth (Azimuth Adjusting
Knobs) directions to place Polaris in the same position on the Polar Scope Dial as indicated on your
iPhone/iPad screen. In this case, the Polaris will be located at a radius of 40.2' and an angle of 00
hour 18.4 minute.
If you feel the polar scope LED is not bright enough, or too bright, you can adjust it. Press and
hold the Function Button
button again until the LED beneath the " " is on. Now you can press ◄ or ► to adjust the polar
scope illumination intensity.
When done light intensity adjustment, double check the LED under letter "S" to make sure the
correct hemisphere is selected.
Now you are ready to track the sky! Point the camera to the sky you are interested in.
