What is the map of the stars?

There are four seasons on the map: spring, summer, autumn and winter. There are two in each season: one is the starry sky facing north, and the other is the starry sky facing south. In other words, one is from the north and the other is from the south. When you look at the stars, you use the North Star Map facing the North Station and the South Star Map facing the South Station. These two pictures are synthesized at the zenith from the east and west, which is the whole starry sky on the horizon.

The lines between the stars are added for the convenience of identifying the stars, but there are no such lines in the starry sky. On the star map, bright stars are big and dark stars are small, and the name is the name of the constellation. Passing through the brighter part of the starry sky is the general outline of the Milky Way.
