As night falls, the stars shine. If you look up at the stars, you will find a mysterious world. Look at the stars occasionally at ordinary times. Maybe you just need to look at them, but if you really care and want to get in touch with the beautiful night sky, you need to be fully prepared. Maybe you think it's a mountain out of a molehill, but it's not, because stargazing is really influenced by light, and choosing a bad position will inevitably affect the effect of stargazing.
What common sense and necessary knowledge do you need to prepare for stargazing? Let National Geographic's Ultimate Stargazing Guide tell you the answer. This is a very suitable guide for beginners. In this book, the author focuses on the selection of observation points, the basic knowledge of astronomy, the composition of more than 50 constellations and legends, the different star maps of the four seasons, how to observe solar and lunar eclipses, and matters needing attention. This necessary knowledge will enable you to observe the stars smoothly, judge what a star is and what a planet is, and how to distinguish constellations through a suitable telescope.
To prepare for stargazing, you must first choose a suitable observation point. "The darker the position, the better," wrote the book National Geographic's Ultimate Guide to Stargazing. Rural or suburban parks are more suitable than light-polluted city streets. If you watch the stars at home, turn off all the lights as much as possible; When you go to the countryside to see the stars, you must find a place with your back to the city and away from light pollution. " If you need to use a flashlight when consulting the stargazing guide, you can wrap a layer of red cellophane on the general flashlight, or directly use a flashlight with a red filter, because the influence of red light on night observation is much smaller than that of white light.
Looking up at the night sky, you can see stars, planets, galaxies and fast-moving celestial bodies through a suitable telescope. These beautiful scenes will make people very excited. But besides, there are five coolest things in the sky. Which five? They are: the Big Dipper and the North Star; Venus; Perseid meteor shower, Pleiades star cluster; Andromeda galaxy. The Big Dipper and the North Star are well known, and their advantage is that they can help people find their way. When watching the stars, they can also use the seven stars as a guide to find other targets. Venus, as the closest planet to the earth, is the brightest, and it will change with the seasons. As for other cool things, it will be clear at a glance after reading the book.
Constellation is a topic that many people care about, among which the twelve constellations are the most typical, but other constellations are equally beautiful, especially when observed under the night sky, which has unique charm. In the book, the author not only introduces the constellation diagram of each constellation in detail, but also tells the myths and legends about the constellation. How to find Andlau Moda, the book says: "In ancient Greek mythology, Ethiopian princess Andlau Moda was chained to a stone and sacrificed to God. Andromeda in the sky, Andromeda, is a V-shaped constellation that looks like a head and feet. " The myths and legends about Andromeda are also very touching. When Andlau Meda was about to be sacrificed to God, Poerxiusi turned the sea monster into a stone with the head of Medusa, the gorgon.
This constellation introduction and myths and legends are explained in detail in the National Geographic Ultimate Stargazing Guide. This can not only help stargazers find constellations, but also make people understand the corresponding myths and legends and master more constellation knowledge.
In the last part of the book, the author also introduces in detail how to choose the stargazing equipment-telescope, and also teaches how to use the telescope, which is very necessary for stargazers.
Stargazing is a pleasant thing. If you can know some necessary common sense in advance, you can avoid unnecessary trouble when watching stars. In the book, the author also advocates taking children to watch the stars together. It will be more meaningful to explain some astronomical knowledge to children when watching stars.
The National Geographic Ultimate Stargazing Guide is rich in content, with various color pictures, which clearly tells the basic knowledge of astronomy. For those who really want to see the stars, this is definitely the ultimate guide.
