Remove all the stars from the sky.

Looking at the starry sky and countless stars, do you feel very confused? Looking at the dazzling starry sky, how to find the constellation you want accurately in the shortest time? In addition to theoretical knowledge, there are some simple gadgets that will be powerful weapons to help you. The first one, the star map, can be bought in some specialty stores. If it is an all-sky map, all the constellations will be marked on it.

Basically, the main bright stars of each constellation are connected by lines in the star map. Each star map will be accompanied by a detailed instruction manual, which is very helpful for you to use the star map correctly. Be sure to read carefully. As long as you find a star or a constellation in the starry night sky, you can rely on the star map to find other constellations in the sky. Compared with the virtual picture of the sky, the star map is a real picture. When you use a star map, you must distinguish between southeast and northwest. When you can't tell the north from the south and can't determine the position of the North Pole star, a simple compass can be your good helper. Leave the question of direction to the compass, and then test your proficiency in using the star map.

However, most of today's big cities are cities that never sleep, and the light pollution is serious. The naked eye can only see a few brighter stars, but the darker ones can't be seen, let alone identify the constellations. At this time, a small family astronomical telescope will be your most powerful helper. Even some deep-space celestial bodies and nebulae invisible to the naked eye can be observed through telescopes. Small astronomical telescopes with different prices see different clarity, so we should choose according to our actual situation.

Light pollution and air pollution, these increasingly serious environmental problems make the starry sky more and more blurred, and also increase the difficulty of people's observation. In the suburbs or mountainous areas far away from the city, there will be better observation results. In order that we can see the starry sky better, everyone should enhance their awareness of environmental protection and work hard for the beauty of the earth.
