How to observe the constellation 12 in the sky?

Constellations are all seen directly with the naked eye, and only with astronomical telescopes can they be seen one by one.

To identify the constellation, you must compare it with the star map. I suggest you download an electronic star map. For example, you can download the English version of SkyMapPro 8 software demo version and the Chinese version of SkyMapPro 8 demo version (updated on February 9, 2002) in http://lzq.lamost.org/software.html#vma., and then you can view the starry sky anytime and anywhere. You can compare it.

What you can see this season is Sagittarius, Scorpio and Libra.
