Zusammenfassung:PROBLEM TO BE SOLVED: To obtain an imaging apparatus which can image a celestial body in a stationary state only by fixing the apparatus without using an equatorial telescope.SOLUTION: Control means calculates a movement locus of a celestial body image relatively moving with respect to an imaging apparatus due to the rotation of the earth from inputted positional information, imaging azimuth information and imaging height information, and controls drive of a subject image movement mechanism on the basis of the result of calculation to constantly maintain the position of the celestial body image on the imaging element constant. The control means, after a release switch included in the imaging apparatus is turned on as a trigger to perform imaging while maintaining the position of the celestial body image on the imaging element constant, and before the start of exposure of the imaging, receives inputs of positional information, imaging azimuth information and imaging height information, and performs calculations for the exposure while maintaining the position of the celestial body image on the imaging element constant. 【課題】赤道儀を使用せずに、固定するだけで天体を静止した状態で撮影できる撮影装置を得る。【解決手段】制御手段は、入力された位置情報、撮影方位情報及び撮影高度情報から、地球の自転によって撮影装置に対して相対移動する天体像の移動軌跡を演算し、それに基づいて被写体像移動機構を駆動制御して、天体像の撮像素子上での位置を一定に維持する。制御手段は、撮影装置に備えられたレリーズスイッチが天体像の撮像素子上での位置を一定に維持しながらの撮影を実行するトリガーとしてオンされた後、当該撮影の露光開始前に、位置情報、撮影方位情報及び撮影高度情報の入力を受けて、天体像の撮像素子上での位置を一定に維持しながら露光する為の演算を実行する。【選択図】図5
