How to use the active star map?

The active star map is used in this way: turn the disk above and align the time with the date, so that you can see the sky scene from the hollowed-out window. You can set any date and time to know what you can see when you go out any night of the year. Remember, when using the active star map, the outer edge of the window represents the 360 horizon around you.

The center of the map represents the zenith. If you want to see what is in the southern sky, you can face the south and draw an active star map with the "South" marked on the star map at the bottom. At this time, the constellation near the edge of the window will appear in the lower part of the sky, and the constellation between the center and the edge will be at a comfortable height. Now turn to the eastern sky and let the "East" of the active map point to the ground.

When turning north, turn the hand with the map 1/4 times (let "North" point to the ground). Then ... well, you must already know how to use the map!
