Is it better to use constellation or 720 rotation for globe?

This is called an astrologer. The first mechanical miniature of the solar system was made by hand according to the clock manufacturing technology.

The mechanical astrologer in Gotha Museum is made by David Hahn) 1780 Duke Ernst II.

Direct mechanical optical projection planetarium is gradually familiar with the definition of planetarium at present: planetarium, sun, moon, its stars, planets and literary objects are projected to show darkroom, and hemispherical screen planetarium simulates starry cloth in the same room and position. The combination with media makes the demonstration of planetarium special.

Important planetariums project celestial bodies other than stars and the sun, and various planetary planetariums can simulate the projection of constellation portraits, making the demonstration more interesting.

Bring an astrologer and a screen so that you can watch the astrologer's demonstration outside the museum.
