COMPOUND TYPE PLANETARIUM SYSTEM, INDIVIDUAL OPTICAL TYPE CELESTIAL BODY PROJECTOR AND CELESTIAL BODY PROJECTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a compound type planetarium system, an individual optical type celestial body projector, and a celestial body projection method capable of reproducing displacement of respective celestial bodies, and also a proper motion because of passage of long years, by freely changing a view point, in a state of maintaining a real and clear starry sky.SOLUTION: The invention comprises plural individual optical type celestial body projectors 40 comprising a function for projecting a dot-state celestial body image on a prescribed coordinate on a dome screen. When plural celestial bodies are projected on the dome screen, among the plural individual optical type celestial projectors 40, the individual optical type celestial projectors for projecting the respective celestial bodies are selected and allocated, and during the projection, the allocation is kinetically changed. Even when coordinates of the respective celestial bodies are changed on the dome screen, the starry sky can be reproduced in a wide range on the dome screen, relative to a case in which the celestial bodies are projected by specific individual optical type celestial body projectors.SELECTED DRAWING: Figure 6
