1. Overview
PoleMasterTM - a high precision, easy to use
electric polar scope.
Achieving a high precision polar alignment is
not an easy feat. You may spend tens of
minutes, if not hours, to have a good polar
alignment. After you get everything ready and
begin taking exposure, you bumped the mount,
and you have to restart from the beginning. An
iOptron’s Center-balanced Equatorial Mount
(CEM), such as CEM25 and CEM60, which
equipped with an all time accessible polar
scope, will allow you to make a quick and
precise polar alignment in a few minutes.
However, you still need to bend yourself, or
knee down on the ground to perform the polar
alignment
The most straight forward way for polar
alignment is just to find the true north point and
match its position with the rotation center of
your R.A. axis. The PoleMaster
polar scope employs this idea. This device can
be installed on front of the R.A. axis. It use a
highly sensitivity camera to capture the image
of northern sky. The sensitivity is much higher
than the naked eye, so it can see not only the
Polaris but also those faint stars nearby.
Based on the locations of these stars, it can
calculate the position of the true position of
North Pole. With some sophisticated methods
the PoleMaster can also detect the rotation
center of the R.A. axis. It will mark the two
points on the computer screen, one is the R.A.
rotation center, the other is the virtual polar
point. Adjust the mount and let them overlap
then the pole is well aligned.
PoleMaster
TM
electronic polar scope provides
a quick and easy solution. It gives you a direct
and simple way to align with the pole. Within
two minutes you could obtain a very high polar
alignment precision up to 30 arcsec.

2.3. Focusing PoleMaster Polar Scope
Each PoleMaster’s lens is focused manually
before shipping from factory. Shall the needs
for refocusing arises, e.g., stars are not
sufficiently small and tight, please follow the
steps below to focus the lens:
1) Point the PoleMaster on bright stars
2) Holder the front protective tube by
rotation and turn CCW to remove it
3) Use a M1 hex key to unscrew the set
screw (focus locking screw) on the side
of the lens barrel
Push the ZEQ25 mounting adapter all the way
into the ZEQ25 polar scope opening. Turn the
socket head screw clockwise to tighten the
ZEQ25 mounting adapter.
4) Turn the lens slowly until the star is well
focused
5) Retighten the set screw and reinstall
the protective tube removed.
3. Install the Software and Use
the Polar Scope
There are two software need to be
downloaded: One is Camera Driver that will
provide the interface between the PoleMaster
Camera and your computer. The other is the
PoleMaster application software that will help
you to do the polar alignment.
1) Download and save PoleMaster camera
driver on your computer. Install it by click
on the downloaded file;
5
2) Download and save PolaeMaster polar
alignment application software on your
computer. Install it by double click on the
downloaded file. There will be a
PoleMaster icon on your computer desktop
3) The software supports the southern
hemisphere. You may display a star
template for either northern or southern
hemisphere by pulling down the Tool
menu.
3) Setup your equatorial mount at Zero
Position (or Up North Park Position).
Roughly level the mount (precise leveling
via bubble is not needed). Point towards
the north as you normally do during polar
alignment process, if you are located in
northern hemisphere. Adjust the mount
latitude to match your location.
4) Launch PoleMaster application. Click on
the Connect button on the top menu bar. If
the PoleMaster is connected to the
computer correctly, the other function
buttons, such as Region Selection, will be
turning active. Select your region and
adjust the camera Exposure and Gain to
display many stars near the Polaris. As
PoleMaster has a very large field of view
(FOV) of 11ºX8°, Polaris should be readily
shown on screen which should the
brightest star in the FOV;
5) The application will assist you to confirm
the Polaris (or Sigma Octane) using the
Template from the Tools pull-down menu.
6) Follow the on screen instructions to
perform coarse (Rough) polar alignment.
The accuracy achievable in this stage is
around a few arcminutes. Now you can
start to observe;
7) If a higher alignment precision is needed,
follow the on-screen instructions to perform
fine polar alignment. The maximum
alignment accuracy achievable after this
stage is 30 arcseconds.
Note:
1) Current version is suitable for use from
November 2015 till June 2016.
2) The software has an option to correct
the atmospheric refraction effect at low
latitude. If you are at latitude lower than
30°, you may activate the correction
from Tools pull-down menu.
4) Under severe light pollution sky or
when transparency is low, PoleMaster
may fail to perform plate solving when
some faint target stars are invisible.
4. Maintenance and Servicing
4.1. Maintenance
The PoleMasterTM electronic polar scope is
designed to be maintenance free, except the
camera driver and/or application firmware
upgrade. Do not drop the camera. Do not plug
the camera using a different cable. Clean the
lens only with lint-free cloth and optical lens
cleaner, when needed. Use a damp cloth to
clean the camera outside. Do not use solvent.

6. FAQ
6.1. Why the calculated pole position is
jumping slightly?
Atmospheric agitation will cause the star
position changed a little and cause the results
jumping slightly. You can watch the most
common position of the calculated positions
and based on this position to adjust the mount.
In a low signal to noise condition, such as the
background light pollution is heavy or a lot of
cloud which will cause the star control is not
good, the calculation random error may
increase and the jumping will be bigger than
expected.
determined by calculation while rotating the
mount.
6.3. How to use in low latitude area?
At low latitude, the atmospheric refraction will
cause the Pole Position not on the geometric
position we are seeing. This effect has been
taken into account when calculating the Pole
Position in version V108 and later.
6.4. When use the mouse to click on the
star, do I need to move the mouse onto
the star precisely?
No, you don’t need to. The software will
calculate the star position rather than use the
mouse cursor XY position
6.5. Why some star is not round?
The lens used in PoleMaster is working at
maximum F-STOP. It has some optic
aberration and will cause some star not round.
However, it usually won’t affect the calculation
because the software use the weighted
centroid algorithm to determined the star
position.
If the jumping is very big, or sometime all over
the image, you need to check if there are
correct stars in the two green rectangle box.
Make sure the correct stars are in
them.
6.2. When installing PoleMaster, does it
need be parallel to the R.A. rotate axis?
No, it does need. Approximately aligned to the
RA axis is ok. The rotating center is
6.6. When using the PoleMaster, should
I stop the mount RA tracing?
No. It is best to keep the mount tracing while
using the PoleMaster.
