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 purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the drawings in the embodiments of the present invention:

[0038] Such as Figure 1-Figure 5 Shown: a kind of manufacturing method of cable star card, mainly has the following steps:

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

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 manufacturing method of a star observation tool, in particular to a manufacturing method of a cable star card. Background technique [0002] The cable star card is a star observation tool for observers to select and recognize stars. Usually, a set of star cable cards includes two floors in the north and south and thirteen transparent horizontal coordinate grids for north and south, which can be used for latitude interfering It is used for star selection and star recognition by surveyors between 0°-60°. The existing methods for 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. Contents of the invention [0003] The present invention is aimed at the proposal of above problem, and the manufacture method of a kind of Suo Xing card that proposes has f...
