Important constellations in autumn

In autumn, the bucket handle of the Big Dipper points to the west, but the Big Dipper may be very close to the horizon and difficult to find, but we can use another sign-Cassiopeia, which is in the Milky Way. See that m? Yes, that's it. Try to stretch from the star in the middle of the "M" in the direction perpendicular to the Milky Way and in the protruding direction. The first bright star we met was Polaris, which is located in Ursa minor. Did we all find it by Beidou before? After finding Cassiopeia, follow the southwest direction of the river to find the familiar cross cygnus, and return to the northeast direction of the river to see Perseus. Still looking south from Cassiopeia, four bright stars form a big square, which is the representative seat of the autumn starry sky-Pegasus. Further south of Pegasus are Aquarius and Pisces. Although there are no bright stars, they are all zodiac signs. You can check the star map.

"Flying horse in the sky, the Milky Way hanging obliquely" is a symbol of the starry sky in autumn.

From the "autumn quadrangle" (also known as "flying horse-fairy box"), patrol the autumn starry sky towards the head.

At first, this quadrilateral is like a square. When it is in the direction of the head, its four sides just represent each other.

One way. The autumn quadrangle consists of three bright stars (α, β, γ) in Pegasus and one bright star (α) in Andromeda.

Composition, very eye-catching

Extend the east side line of the quadrilateral to the northern sky (that is, from Pegasus gamma star to Andromeda alpha star), and pass through

Cassiopeia, you can find Polaris, and along this baseline you can find a bright star (β) in Cetacea. This is long.

The long north-south line is almost at the right ascension Oh position. It is convenient to remember and estimate the position of the stars.

Extend the west side line of the quadrilateral to the south sky (that is, from Pegasus beta star to alpha star), and the south is low.

In the sky, you can find the famous bright star in the autumn sky-Beiluoshimen (Alpha Pisces), and extend northward along this baseline to find the fairy.

Throne.

From the northeast corner of the quadrangle in autumn to the northeast along Andromeda, Perseus composed of three rows of stars can be found.

Seats. To the southeast of the quadrangle in autumn are Pisces and the Great Whale. Fairy king, fairy queen, fairy, fairy, flying horse and

The whale constellation constitutes a brilliant royal constellation and is the main constellation in the autumn sky. The southwest of autumn quadrangle is

Aquarius and Capricorn.

There are few bright stars in the autumn sky, but there are many deep-space objects like Andromeda Extragalactic Galaxy (M3 1).

PS:

The big square in autumn

Pegasus' abdomen. These four stars are arranged in a square and hung high in the sky.
