What is the detailed meaning of stargazing?

Altitude refers to the height of the observation site, that is, the height of the ground relative to the sea level. The change of altitude will have some influence on stargazing.

Atmospheric transparency: With the increase of altitude, a clearer sky and better atmospheric transparency can usually be obtained. There are usually fewer factors such as air pollution, dust and humidity in higher altitude areas, which will affect the light propagation and observation quality. Therefore, the observation conditions in high altitude areas may be more ideal. With the increase of altitude, the atmospheric pressure will gradually decrease and the temperature will also decrease. These factors may affect the performance and calibration of telescopes and other observation equipment, as well as the comfort of observers. There is also the field of vision: observation sites located at higher altitudes can usually get a wider field of vision. Without the restriction of obstacles such as mountains, buildings or trees, celestial bodies in all directions in the sky can be better observed.

Visibility of observation targets: Some celestial bodies and astronomical phenomena are easier to observe in certain seasons or certain latitudes. At higher altitudes, because you are closer to the sky, you may see some celestial bodies that can only be seen at low latitudes. Here we recommend the master of astronomy, which contains rich information such as the position, brightness, elevation angle and height of the star.
