Problems solved by technology

The existing methods of making cable star cards have relatively single functions: a set of cable star cards can only use a single method to identify stars, which is extremely inconvenient for users who have mastered other methods of star identification

Embodiment Construction

[0037] In order to make the purposes, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention:

[0038] like Figure 1-Figure 5 Shown: a method for making a Soxing card, which mainly includes the following steps:

[0039] S100: Because the positions of the star image points on the Soxingka star map are all fixed, in fact, there will be slight differences in the apparent positions of stars in different years and months, so the average position of each star needs to be calculated. Since the annual apparent positions of stars change slightly in a 4-year cycle, the astronomical calendar of the year between two adjacent leap years (such as 2002 and 2006) can be used to query the astronomical calendar of each star in each month. A method of averaging ...

Abstract

The invention discloses a star finder manufacturing method which comprises the steps of: calculating the average position of each common star in the year; projecting the average position of each common star on two bottom plates respectively by adopting positive-axis azimuthal equidistant projection, and marking a right ascension graduated ring, an equator image, an ecliptic image and a mean sun graduated ring on southern and northern bottom plates; converting horizontal coordinates of each node of a horizontal coordinate net into equatorial coordinates, and protecting the coordinates on a transparent plate to be taken as a transparent coordinate net piece; and marking a minus 6-degree altitude parallel ring and a local mean time graduated ring on the transparent coordinate net piece. By adopting the manufacturing method of a star finder provided by the invention, the manufactured star finder can be used for selecting and recognizing stars by a minus 6-degree altitude line method, a vernal equinox local time angle method and a local mean time method, so that a user who masters different star selecting and recognizing methods can conveniently use the star finder, and more star selecting and recognizing methods can be achieved compared with the star finder manufactured by the traditional method.

Description

technical field [0001] The invention relates to a method for making a star observation tool, in particular to a method for making a Soxin card. Background technique [0002] Soxing card is a kind of star observation tool for observers to select and recognize stars. Usually a set of soxing card contains two floors of north and south and thirteen pieces of transparent horizon coordinates for both north and south. It is used for star selection and star recognition by the surveyor between 0°-60°. The existing methods for making Soxing cards have relatively simple functions: a set of Soxing cards can only use a single method to recognize stars, which is extremely inconvenient for users who have mastered other methods of star recognition. SUMMARY OF THE INVENTION [0003] The present invention addresses the above problems, and proposes a method for making a Soxing card with the following steps: [0004] S100. Query the astronomical calendar of the year in the middle of two adj...
