How to use the star map

1. Because the map is looking down and the star map is looking up, the east-west direction of the star map is just the opposite of the map.

2. This means what angle to look at the star map on different dates. The starry sky is different at different times.

When using the star map, you need to first determine which season you are watching, as well as the specific time and latitude and longitude.

As long as the latitude is different, the stars you see are different. The stars seen at the same latitude are the same. The closer you get to the poles, the fewer stars you can see. You can see all the stars on the equator.
