Electronic star-finding mirror, astronomical telescope, and electronic star-finding computing device

Abstract

The invention discloses an electronic star-finding mirror, which is used for assisting a main telescope of an astronomical telescope to find a target object. The electronic star-finding mirror comprises an imaging unit and an optical lens, wherein the imaging unit comprises an optical lens and is used for imaging the target sky area; an image sensor disposed on a focal plane of an optical lens ofthe imaging unit for sensing an image of a target day region obtained by the imaging unit; and a calculation unit that receives the image from the image sensor and is configured to perform the following processing based on the image: extracting a star point in the image; and identifying the star point in the image to obtain the name and/or the equatorial coordinate of the star point by matching the star point with the star table database. The application also discloses an astronomical telescope comprising the electronic star-finding mirror and an electronic star-finding computing device whichis used for matching with an electronic star-finding mirror. Compared with the traditional optical finder, the electronic star-finding mirror is more convenient for operation and use.

Description

technical field [0001] The present invention generally relates to the field of astronomical telescopes, and in particular, relates to an electronic finder for assisting a main telescope of the astronomical telescope in finding a target celestial body, an electronic finder computing device and an astronomical telescope including the electronic finder. Background technique [0002] A traditional optical finderscope is mounted on the main telescope and is an independent small telescope consisting of an objective lens and an eyepiece, usually containing a crosshair. Its main function is to guide the main telescope to the target to be observed. The principle is that the field of view of the optical finder is relatively large, so it can be used by the user to find the observed target in a large range. Thereby guiding the main telescope to move to the observation target. [0003] The cross hair is used to superimpose the center position indicator on the scene observed by the user...

AI Technical Summary

Problems solved by technology

[0005] In addition, the traditional optical star finder can only indicate a central position, and it needs to be adjusted before finding the star so that its optical axis coincides with the optical axis of the main telescope, so it is not convenient to use

Especially for observers who do not have astronomical foundation, the optical finder cannot assist the observer to find the target celestial body that needs to be observed
