Astronomical site-selecting instrument guide star device and working method thereof

Abstract

The invention discloses an astronomical site-selecting instrument guide star device and a working method thereof. The astronomical site-selecting instrument guide star device consists of a lens, a camera and guide star software, wherein an output signal is connected with an equatorial telescope. The astronomical site-selecting instrument guide star device is characterized in that an automatic guide adapter is arranged between the guide star software and the equatorial telescope. The automatic guide adapter is composed of a micro controller and a four-path switch switcher; the camera is used for continuously taking a candid photograph of the target area, and providing the candid photograph to the guide star software through a computer; the guide star software is used for processing the target area image, identifying a target celestial body, and sending the target celestial body position correction amount to the automatic guide adapter which controls the movement of the equatorial telescope. According to the astronomical site-selecting instrument guide star device disclosed by the invention, a star searching function and a star guide function share the same hardware, the device is simple; the target celestial body is automatically identified through an algorithm, and the astronomical site-selecting instrument is assisted to automatically search and point the target celestial body; the correction amount of target celestial body position is calculated in real time through the algorithm, and fed back to the equatorial telescope through the automatic guide adapter, so that the target celestial body is automatically tracked; when a telescope is caused to shake by wind load, the target celestial body also can be tracked.

Description

technical field [0001] The invention belongs to the field of photoelectric instruments, and in particular relates to an astronomical site selection instrument guide star device and a working method thereof for searching and automatically tracking celestial bodies. Background technique [0002] In view of the cost advantage of amateur equatorial astronomical telescopes, astronomical siting workers usually use them as monitoring devices for atmospheric turbulence. However, the geographical and meteorological conditions of the observatory site determine that it is necessary to modify and increase the functions of the amateur equatorial astronomical telescope, so that it can automatically find and guide stars and achieve long-term operation. [0003] On the one hand: At present, the guide star device uses a camera to collect the image of the target celestial body, and sends a correction signal to the equatorial mount or the tilt mirror system (also known as the tilt mirror ...

AI Technical Summary

Problems solved by technology

[0005] In summary, amateur guides can provide reference solutions, professional guides are very expensive, but they do not meet the needs of astronomical siting

That is to say, the main problems existing in the existing technology are: (1) professional guide star devices are very expensive, and relatively cheap guide star devices are more suitable for astronomical siting instruments; (2) amateur star guide devices cannot take into account star finding; (3) in the When the wind load is large, the guide star function of the amateur guide star device fails; (4) the current guide star device cannot ensure the long-term automatic operation of the astronomical site selection instrument, that is, the reliability is poor
