Recommend books on astronomy and constellations.

First of all, I strongly recommend "Beautiful Starry Sky" (revised edition of popular stargazing handbook).

This book is very good and comprehensive. Almost everyone, whether novice or expert, has it. This book is very cheap, 38 yuan, 378 pages, printed in black and white.

Then, the latest edition of "Beijing Planetarium: A Manual for Astronomers", 180, 29 yuan, is absolutely exquisite.

Secondly, it is extremely beautiful: starry sky (recommended by Beijing Planetarium).

This is a beautiful starry sky. This book takes readers to the starry world that makes them linger through exquisite pictures, beautiful pictures, movies and various charts. No matter where in the world, you can find the exact location of the stars. This is a very practical star map reference book, and it is a necessary reference book for astronomy lovers. With it, it's like moving the planetarium home.

In fact, you can buy a star map first: there are new all-sky star maps and century star maps.

In short, there are many. You can also subscribe to Astronomy Enthusiast magazine, which is the largest and most influential astronomical journal in China, with a monthly issue of 10 yuan.

I hope my answer is helpful to you.
