To maximize the benefits of the iOptron polar scope
for polar alignment, you need to know where the
Polaris is in the northern (Sigma Octantis in southern)
hemisphere. You may find this information via an
iPhone/iPad app (Search iOptron Polar Scope in
Apple iTune store). As shown in a screen shot of an
iPhone, on August 10, 2016, 17:50:18 in Boston, USA
(Lat N42°30’28” and Long W71°08’49”), the Polaris
Position is 00hr 18.4m and Radius is 40.2min (the
green cross on the chart).
Adjust the mount in latitude (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
center round button
until the LED under letter “S”
start to blink. Release
button. Press and hold
button again until the LED beneath the “
” is on.
Now you can press ◄ or ► button 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.
