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 the side-by-side cross-view method. The left frame shows the right eye's perspective, and the right frame the left eye's perspective. It might be possible to view this image without a viewing device by crossing your eyes to visually combine the frames. |

English: Pleiades - the movement of stars in -/+ 200 000 years.
To view this picture you need cross-eyed viewing.
Slovenčina: Pohyb M45 za 400 000 rokov (-200 000 až 200 000 rokov).
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.: hĺbka 3D priestoru je modifikovaná logaritmicky, t.j. hviezdy, ktoré sa nám javia na dvojnásobnú vzdialenosť, sú v skutočnosti vzdialené až 10-násobne. Na prezeranie animácie treba zvládnuť tzv. škuľavé pozeranie. |
