Embodiment Construction

[0047]The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention and the accompanying drawings. Apparently, the described embodiments do not limit the present invention.

[0048] For this reason, the present invention provides a method for synchronizing the equatorial mount for ground-based observation of the moon. With the help of a large field of view finder mirror, the coordinate system of the equatorial mount is automatically synchronized before each lunar data collection, ensuring the pointing accuracy of the spectrometer to the moon. It meets the needs of ground-based automatic observation of the moon. It mainly includes the recognition of the real-time image position of the moon, the calculation of the offset between the position of the moon image and the alignment position, the correction of the moon pointing in the direction of right ascension, the correction of the moon p...

Abstract

The invention relates to an equatorial telescope synchronization method, aims to solve the technical problems of large manpower consumption and large precision error caused by the fact that an equatorial telescope synchronization correction method in the conventional astronomical observation field adopts a manual observation and adjustment method, and provides a foundation moon-to-moon observationequatorial telescope synchronization method. The method employs a finderscope to recognize the geometry center of the moon through image processing; the equatorial telescope can be synchronized without strictly aligning a slit type spectrograph with the optical axis of the finderscope, and a minimum circumscribed circle algorithm adopted for identifying the geometry center of the moon is not influenced by the lunar phase, and the center of the lunar sphere can be accurately identified without judging the lunar phase; the equatorial telescope is synchronized through the geometry center of themoon, additional star map data is not needed, and the synchronization method is accurate, simpler and more convenient.

Description

technical field [0001] The invention relates to a method for synchronizing an equatorial mount, in particular to a method for synchronizing an equatorial mount for ground-based observation of the moon. Background technique [0002] As a highly stable radiation source, the moon is of great significance to carry out ground-based lunar observations and establish a full lunar phase cycle lunar radiation model for on-orbit calibration of the moon. Such as figure 1 , the ground-based lunar observation system is composed of slit-type spectrometer 01, large-field finder mirror 02, equatorial mount 03, and industrial computer 04. The equatorial mount 03 is used as a turntable, and the slit-type spectrometer 01 is installed on the equatorial mount 03 Above, the starfinder 02 is fixed on the slit-type spectrometer 01, and the starfinder 02 and the slit-type spectrometer 01 move synchronously under the drive of the equatorial mount 03, wherein the slit-type spectrometer 01 is used to c...
