Sky chart is an ancient star chart, which is used to predict weather, solar terms and time. It is drawn according to the distribution and movement of the stars in the sky, and it is one of the important tools of ancient astronomy and astrology in China. Drawing the sky disk map requires certain astronomical knowledge and computing power. Here is a simple drawing method.

First, you need to prepare some tools and materials, including: astronomical telescope, star map, calculator, pen and paper. Then, according to the season and time to be painted, choose the appropriate observation point and determine the observation time. Generally speaking, star mapping needs to be done at night, because only at night can the stars in the sky be clearly seen.

Next, observe the stars and constellations in the sky with an astronomical telescope. When observing, we need to pay attention to the position and motion law of the stars, as well as their relative positions and distances. Then, according to the observation results and the star map, the coordinates and trajectories of the stars are calculated by a calculator. This step requires a certain amount of computing power and astronomical knowledge, because the coordinates and trajectories of stars are precisely measured and calculated.

After calculating the coordinates and trajectories of the stars, you can draw them on the star map with pen and paper. When drawing, we need to pay attention to the relative position and distance between the stars and their tracks in the sky. At the same time, the sky map should be adjusted and revised according to the changes of seasons and time.

Finally, a complete chart can be obtained by sorting out and perfecting the drawn chart. In the process of drawing the star map, we need to pay attention to details and accuracy, and we also need some patience and perseverance. Only in this way can we draw an accurate, clear and beautiful sky chart.

In a word, the sky chart is an ancient star chart used to predict weather, solar terms and time. Drawing the sky disk map requires a certain amount of astronomical knowledge and computing power, as well as patience and perseverance. By drawing the sky chart, we can better understand the movement law and distribution of stars in the sky, and can also better predict the future weather and solar terms changes.
