Abstract
A method of automatically tracking and photographing a celestial object, includes inputting latitude information, photographing azimuth angle information and photographing elevation angle information of a photographic apparatus; inputting star map data of a certain range including data on a location of a celestial object from the latitude information, the photographing azimuth angle information and the photographing elevation angle information; calculating a deviation amount between a location of the celestial object that is imaged in a preliminary image obtained by the photographic apparatus and the location of the celestial object which is defined in the input star map data; correcting at least one of the photographing azimuth angle information and the photographing elevation angle information using the deviation amount; and performing a celestial-object auto-tracking photographing operation based on the corrected at least one of the photographing azimuth angle information and the photographing elevation angle information.
