This file is a stereogram. Stereograms are stereoscopic images or animations which combine left and right frames showing slightly different visual angles to allow for 3D perception.
The stereogram uses an anaglyphic method of stereoscopic 3D presentation which is unspecified or unrecognized by this template. (If a suitable option is available, please add or correct the parameters to indicate the type of anaglyph used.) Some type of two-color 3D glasses are recommended to view this image correctly. |

Summary edit
| Description |
English: The movement of stars of spectral classes B and A around the apex (left) and antapex (right) in -/+ 200 000 years.
Slovenčina: Vlastný pohyb hviezd spektrálnych tried B a A na oblohe za -/+ 200 000 rokov.
Na obrázku vidíme vlastný pohyb mladých modrých hviezd na oblohe. Zobrazené sú hviezdy do 8 mag. Na pohybe týchto hviezd sa vlastne odzrkadľuje pohyb nášho Slnka v galaxii. Vidíme, že za veľmi krátku dobu existencie týchto hviezd sa ich pohyb len málo rozladil. |

Poznámka. Na prezeranie tejto animácie sú potrebné 3D okuliare s farebnými filtrami červená-zelená, príp. sa dá dosiahnuť uspokojivý výsledok aj červeno-modrými okuliarmi, pritom záleží aj na poradí farieb: červenú farbu treba mať pred ľavým okom, zelenú alebo modrú pred pravým. Hĺbka 3D priestoru je modifikovaná logaritmicky, t.j. hviezdy, ktoré sa nám javia na dvojnásobnú vzdialenosť, sú v skutočnosti vzdialené až 10-násobne.
