Claim:
1. An automatic astronomical observation method comprising providing an automatic astronomical observation system and the steps of automatic star finding, automatic focusing and image storing, wherein, said automatic astronomical observation system comprises: an astronomical telescope, a star finding servo motor for driving the astronomical telescope, and a control system, wherein a focusing servo motor is connected to a lens regulation mechanism of the astronomical telescope; a CMOS sensor used for obtaining a starry sky image is disposed on the astronomical telescope; said control system comprises a control chip, a gyroscope, a memory, and a WIFI communication interface; said control chip is electrically connected to the CMOS sensor, the gyroscope, the memory, and the WIFI communication interface; a handheld device provided with a WIFI communication interface is disposed by being fitted to the control system; and a GPS module is disposed in the control system or the handheld device; said automatic star finding step comprises: getting geographic coordinates and a time information of a current position by the GPS module, checking and obtaining a current sky map using the handheld device; sending a sky map of a celestial body to be observed to the control system from the handheld device; the control system obtains information from the gyroscope for determining an inclination of a tube; according to a deviation between the current position of the tube and a direction pointing to the celestial body to be observed, the control system controls a move of the star finding servo motor, to adjust a horizontal position and an angle of elevation of the tube, to find the star automatically; and said automatic focusing step comprises: the control system controls the CMOS image sensor to obtain an image signal; the image signal is transmitted to the handheld device via the WIFI communication interface; the handheld device processes the image signal, for planets in a solar system, using a maximum value of a high-frequency component of the image signal as a focus aim, for extrasolar stars, using a maximum contrast as the focus aim, the handheld device sends focus information to the control system via the WIFI communication interface for controlling the movement of the focusing servo motor, to focus automatically.
