Astronomical telescope video CCD automatic guiding method

Abstract

This invention relates to one space telescope visual frequency CCD automatic guide method, which comprises the following steps: fixing visual frequency CCD in guide lens cylinder and main lens cylinder; through CCD image process getting space object image; rotating CCD to make the space image parallel along X direction and rectascension or declination for space object imaging by CCD; computer uses visual frequency to catch image for guide according to visual image and its changes.

Description

technical field

[0001] The invention belongs to the field of astronomical telescope research and manufacture, in particular to an astronomical telescope video CCD automatic star guiding method for automatic star guiding of celestial bodies. Background technique

[0002] Astronomical telescopes need to observe a celestial body stably for a long time. To achieve high precision, automatic star-guiding methods and equipment are necessary. At present, there are three methods for the automatic guidance of celestial bodies.

[0003] 1. Photocell automatic guide star. Its disadvantage is that it is basically unusable for dark celestial bodies such as stars due to too low energy, and it is very unstable for bright celestial bodies such as the sun. It is very sensitive to the brightness of the sun, cloud cover, skylight, etc., and its accuracy is very low, so it has basically been eliminated ;

[0004] 2. Linear array CCD or bar CCD automatic guide. Its shortcomings are: the recei...
