Does the constellation observation record have a direction?

Constellation observation records have directions. According to the relevant public information, the direction of the constellation observation record table is generally marked with the direction on the star map. By default, it is north and south, and Zuo Dong is due west. Hold the map above your head when you look at it, so that the direction on the map corresponds to the actual direction. First of all, we can determine the corresponding relationship between the stars on the star map and the actual starry sky according to the bright or special stars (such as Sirius and Polaris) or the arrangement of several star features (such as Beidou, Nandou, Seven Stars of Orion, Summer Triangle, Winter Triangle, Pegasus-Fairy Square, etc.). ), and then we can identify the constellation according to the star map. First find the brightest star in the constellation, and then according to the relative positions of the stars in the star map.
