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
| Description |
English: 4D motion of Hyades.
The movement of stars in -/+ 500 000 years. Animations for red-blue glasses.Slovenčina: 4D pohyb Hyád za milión rokov (-500 000 až 500 000).
Do tejto hviezdokopy patria hviezdy, ktoré vidíme približne v rovnakej vzdialenosti a smerujú do spoločného bodu na oblohe. Ich zdanlivý smer pohybu na oblohe je vo veľkej miere ovplyvnený blízkosťou antapexu, kde sa hviezdy akoby strácali v diaľach. Pozn.: 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. |
