Star Calibration - Omegon Universe2go Instructions Manual

3. Have you permitted Universe2go to
access the microphone?
Note: If the calibration is unsuccessful,
you can measure your interpupillary
distance with the aid of a ruler and
enter it directly into the settings.

on operation.
Note: Nearby metal objects (fences,
pipes, cars, etc.) can adversely affect
the accuracy of the compass in your
Smartphone. You should be several
metres away from any metal objects in
order to ensure precise calibration of
your Universe2go.

2.3 Star calibration

2.3.1 Standard star calibration
10
For Universe2go to be able to
precisely display the real positions of
astronomical objects, three bright
stars need to be targeted.
Note: Please make sure that the cover
of the Star Viewer has been removed,
otherwise you will not be able to see
any stars.
A. If you look at the night sky though
Universe2go, you will see a green
targeting circle and some stars, which
also have green borders. You can see
the name of the stars above them.
Aim at one of these stars, positioning
it in the centre of the targeting circle.
Calibration will commence as soon
as the star is held, motionless, in the
targeting circle. You will see a circular
progress bar, which forms a complete
ring around the star after a successful
calibration.
After calibrating this star, a small red 1
(or, later, a 2 or a 3) will appear on the
display.
B. Now calibrate the second and third
stars, using the same procedure.
After star calibration, you will receive
information regarding current sensor
quality.
If the sensor quality is reported as
being poor, try the following:
Compass is inaccurate:
1. Change your position and ensure no
metal objects are in the vicinity.
2. Repeat the star calibration using a
different star.
Make sure you do not use a star that
is either too near the horizon or too
near the zenith (directly overhead) .
Select stars that are as far as possible
away from each other.
3. Use the "Expert calibration" or
"Compass fine adjustment" in the app
(Android only) .
Gravitation sensor is inaccurate:
Make sure that the Universe2go is
sitting securely on your nose during
calibration. Any vertical movement of
the Star Viewer on your nose during
calibration can lead to poor sensor
quality.
2.3.2 Star calibration with compass
fine adjustment (Android only)
This type of calibration is of use if the
compass is very inaccurate.
