What is the sky map in autumn?

Autumn night sky map. Aquarius, where the spiral nebula is located, is a big constellation in the autumn sky.

Although Aquarius is relatively large, there are no bright stars in this constellation. The brightest star is a third-class star, and * * * has three. These three stars are Aquarius alpha stars, located on the left shoulder of the beautiful boy; Beta star is located on the right shoulder of a beautiful teenager; Delta is located on the leg of a beautiful teenager. There are also four four-level small stars to form an English letter Y-shape. It is not easy to find Aquarius. The starry sky in autumn is not as bright as that in spring and summer. Not far from the south of the Milky Way, there are four bright stars arranged in a quadrilateral, which is the most striking quadrilateral in the autumn sky. All three stars in the quadrangle belong to Pegasus, and the one in the northeast corner is Andromeda A star.

Let's face south, look up and find the striking autumn quadrangle first. Looking south along the quadrangle, just northeast of Capricorn, it is an inverted triangle, and you can see a small string of Y-shaped Aquarius, which is where Aquarius is located. From this small Y-shape to the south, you can see two strings of "water" pouring into the big mouth of the south fish, which is the whole Aquarius. There is a star with brightness of 1 on the mouth of Nanyu, which is the alpha of Nanyu, and the middle is called Beiluo Shimen. It is the brightest star in autumn night. Aquarius is in the dark area between the bright North Luo Shimen and the quadrangle in autumn.

Having determined the position of Aquarius, we can look for today's protagonist spiral nebula NGC7293. NGC7293 is located in the south of Aquarius, near the south of Aquarius, where is the left calf of the beautiful boy. From the southern constellation α, that is, Northrop Grumman to the east, we assume that connecting Northrop Grumman and Capricorn δ star (the star in the northeast corner of Capricorn's inverted triangle), NGC7293 is almost at the midpoint of this line. Move our eyes from the midpoint of the line to the northeast, and we can see the beautiful spiral nebula.
