What do you think of astronomical maps?

Generally speaking, when looking at a map, it is up north, down south, left west and right east, but in Zuo Dong, it is up north, down south and right west. The north and south are the same, but the east and west are opposite.

At this time, just lift the map above your head, with the top facing north and the bottom-up direction consistent. Watch the star map at night, so prepare a flashlight, but it is best to put a red cloth on the flashlight and illuminate the star map with red light, so that your eyes will feel comfortable.

You can easily find the stars in the sky by using the star map. Hold up the map first and position yourself. Find a known star in the sky, then find this star on the map, and then find other stars from this star. You can also use a strong flashlight to shoot the beam into the sky, like a beam indicator, pointing to a star, so it looks much more eye-catching.
