"Tiangong" space station will enter a suitable observation period tomorrow, experts teach you how to look
The transit of the "Tiangong" space station in my country has always been a hot topic, and many photographers have also recorded the beautiful moments of the "Tiangong" transit.
According to astronomy experts, from the 7th to the end of this month, the "Tiangong" space station will pass over my country more frequently, which is a suitable time for our observations.
Come see the experts teach you how to observe the "Tiangong" space station.
According to Zhu Jin, a researcher at the Beijing Planetarium, from December 7 to the end of this month, the "Tiangong" space station will frequently pass through different areas in the sky above my country, and people will be able to see the "Tiangong" transit at a certain time during the night.
"For Beijing, for example, there will be an evening crossing almost every day starting from the evening of December 7th, and it will last about two weeks. In mid-to-late December, except for places particularly to the north, it will affect the whole country. The vast majority of the area is a good time to observe and photograph the transit of the'Tiangong' space station."
Experts say that because the "Tiangong" space station itself has an orbital inclination of 41.5 degrees, it is relatively more likely to see the "Tiangong" transit in southern my country.
So how do we know when and where to observe the "Tiangong" space station?
Zhu Jin said that the observation of this man-made celestial body can detect the forecast of its transit in advance.
Some websites or some applications can be used, such as the "TianTong" applet. You only need to turn on your mobile phone, and it can list all the transit information of the place you are currently located and the "Tiangong" space station in the next 10 days.
After determining the observation time and location, all that remains is how to observe and what to use for observation.
Experts say that in fact, when the "Tiangong" space station transits, due to the reflection of sunlight, its brightness at night can reach a level of negative 2 or so. It is basically similar to many stars or planets we see in the night sky. can be seen.
If you want to take photos, you have to use professional equipment.
"For this kind of man-made celestial body, the effect of using a camera to shoot is much better. Generally shooting is to use a tripod and a shutter release, and then use continuous shooting to take it out." Zhu Jin said, at the same time because of the "Tiangong" transit. The time is constantly moving, so the effect of observation with a telescope is not good.
