Problems with Universe2go:

What should I do if the real stars and the digital image in Universe2go+ are not correctly aligned?
1) Avoid possible sources of error: The compass can be disturbed by any metal object near it. Are you standing on a balcony with metal railing or next to a car or to another metal object?

2) Always aim for bright stars to start with, and then switch from these to smaller stars. Do not turn through 180 degrees in a single sweep, but start by targeting nearby stars one after the other.

Only half of the screen is active, the other half is black.
Universe2go offers the following options:

• Monocular vision with one eye
• Binocular vision with both eyes

If you select the setting for one eye, you will see the screen either with the right eye or the left eye. The free eye has a clear view of the night sky. Tip: select this setting if you have problems with stereo vision or want to share Universe2go+ with a group.

For a stereo view, select “both eyes” in the settings. Now you must also enter your individual interocular distance so that you do not see double images.

You can switch between single-eyed and double-eyed viewing by activating or deactivating “both eyes”.

How can I recalibrate the compass of my iPhone?
When you point at stars with Universe2go+ and your iPhone, do you notice a certain misalignment? An inaccuracy that you did not notice before? In this case it can help to recalibrate the built-in compass. Close the compass and Universe2go+ apps and exit them completely. Then restart the Universe2go+ app.

The display is frozen while the audio is describing an object.
This is intended to prevent you from getting a stiff neck, for example, when you have to look at the zenith for 2 minutes while listening. However, you can cancel the speech output by gently shaking the viewer.

I see double images (that is, the left eye’s image cannot be matched with that of the right eye).
In this case, your interocular distance (also known as pupillary distance) is not set correctly in the app. Please call up the option “Eyes” in the app menu under “Settings”, then select the option “Distance”. Now select the appropriate pupillary distance for you or try out different settings. Tip: if you pass Universe2go+ around a group, it is better to choose monocular vision (so turn off “both eyes” in the settings). Then it is not necessary for each observer to change the pupillary distance settings before they can use the viewer.

The screen does not appear in the centre of the glasses or is offset.
Check the position of your smartphone in the slot and position it as centrally as possible.
