How to find constellations quickly from the starry sky

If you must tell the secret, you can borrow the theme of Ouyang Xiu's article "The Oil Seller": "Without him, only your hands are familiar." Identifying constellations is equivalent to memorizing words, and it is impossible to do it overnight. And the sky is dynamic, which is more difficult than memorizing words. If you can write a season of starry sky once and for all overnight, you are undoubtedly a genius. Personally, I didn't make friends with the stars in the sky until I watched the sunny day for a whole year, and so did my friends around me. Once, twice, three times ... after about seven or eight times, I got to know the starry sky for a season.

Of course, in addition to input, there are some skills. Identifying constellations may start with identifying bright stars. The most striking symbol of summer now is the Summer Triangle, which rises from the northeast after sunset. The one in the south is Altair, the one in the northwest is Vega, and the one in the northeast is Tianjin IV ... After finding the summer triangle, you can know their constellations and distinguish them from Aquila, Lyra and Cygnus. Then you can know other constellations. For example, if the Cowherd and the Weaver Girl draw an equilateral triangle to the southwest, they will find the back (Ophiuchus α) and then Ophiuchus. To the north of Ophiuchus is Wuxian. Looking from the triangle to the south, a bright red star is the antares of Scorpio, and a pair of messy but good stars in the east are Sagittarius. When you can find these constellations accurately (regardless of the length of time), it will meet the passing criteria I mentioned above.

By the way, it is also worth mentioning that everyone in Jin Mu has heard about the planets and the five elements of fire, water and soil, but even in colleges and universities, many people don't know their dazzling light. As long as they appear, they are at least equivalent to the bright stars I mentioned above. These stars may be misleading items for novices to identify constellations. For example, now Mars is at Virgo Expressway and Saturn is walking slowly in Libra. According to the above, I personally experienced many things that regarded Mars or Saturn as antares, which led to the great move of Gankun.

If you have experience, you will know the position of the constellation in the sky. Although it is daytime, I also know that the starry sky in autumn is about to set in the west of the sky, the sun is about to reach the zenith in Gemini, and the starry outpost in spring should just rise. So for me, as long as the latitude is not too south, I can basically connect to the starry sky in three seconds ... Of course, this is the result of more than eight years of wait-and-see and pursuit, so the landlord does not have to worry. Starry sky, there is no need to pay attention to: "10 thousand years is too long, seize the day."
