At night, use Polaris to make directions, which side faces north.

In the northern hemisphere, Polaris is undoubtedly the most important directional star. On the starry background, Polaris is less than 1 from the north celestial pole, so if you find Polaris at night, you will basically find the north.

Polaris is a very important indicator of field activities and ancient navigation direction. From stargazing to astrophotography, the accurate positioning of the Equatorial Observatory in the observation room is also a very important constellation to identify the direction. Because Polaris is closest to true north, people on earth have been navigating by its starlight for thousands of years.

You can find the Big Dipper first, and then find the North Star through the Big Dipper. The Big Dipper is a part of Ursa major. Graphically, the Big Dipper is located at the back and tail of Ursa Major.

Of these seven stars, six are secondary stars and one is tertiary. Through the connection of two stars (Shu Tian and Tian Xuan) in Doukou, Polaris was discovered after extending in the direction of Doukou for about five times. Beginners can look for other constellations in turn from the Big Dipper.
