Use these two websites to check the degree of light pollution. They use colors to distinguish the degree of pollution on the map. Zhangzhou's light pollution star level includes longitude and latitude, and there are Arabic numerals from 1 to 9 underground, and each number has a c

Several factors that affect the shooting of star fields

1. Light pollution
2. Time
3. Weather

So how to check light pollution? Please listen to me one by one.

1, light pollution

Light pollution can be checked through the two websites

. On the map, they distinguish the degree of pollution by color.

Let’s take Zhangzhou Gangliao as an example. Open the website

. There is light pollution in the lower right corner. level or dark night level,

Click the magnifying glass button in the lower right corner, a search box will appear in the upper right corner, the diagram is as follows:

Enter the address you want, for example: Zhangzhou Gangliao

Zhangzhou light pollution star level, latitude and longitude, and underground Arabic numerals from 1 to 9, and each number has a corresponding color module. You can find the corresponding color on the map. Level 1-3 is an ideal environment for shooting stars, level 4 is barely enough, and level 5-9 is not ideal. Condition, light pollution is too serious.

In other words, the smaller the number, the smaller the light pollution environment, and the more ideal the starry sky shooting environment; the larger the number, the more serious the light pollution environment, and the less ideal starry sky shooting environment.

The second step is to view the terrain in . Here I will introduce you to a Xinzhi satellite map. Search on Baidu: Xinzhi satellite map,

Enter Zhangzhou Gangliao in the search box of the map. The diagram is as follows:

The third step is to switch to . Go to the satellite map, the schematic diagram is as follows:

The fourth step, can maximize the new knowledge satellite map, you can also hold down Ctrl + left mouse button on the keyboard (rotate the map left and right); Ctrl + right mouse button (rotate the map up and down); Ctrl + mouse Middle click (zoom map)

The fifth step, use the professional version of the Qiaoshu App to find the direction of the Galaxy . This software is purchased for life, 68 yuan. It can not only see the Milky Way, but also the sunrise, sunset, Meteor shower

(The method I personally use is to find the shooting location on the Xinzhi satellite map, and then use windy to look at the direction to check the weather, etc., and then check the location of the Milky Way using the star walk 2 app)

2. Time

We need to avoid before and after the full moon About 7 days, that is, about 7 days before and after the 15th day of the lunar calendar, because this time period will be affected by the moonlight, and then the beginning and end of the month are the most ideal. Cloud map, now the cloud map is on the right side of windy, and then search for geography in the upper corner. Click on windy to see the cloud cover at the current geographical location. The diagram is 14%. On the right timeline in the lower left corner, you can select the cloud cover in the next few days. Picture, as shown below:

Finally, when you go to the field to visit the scene, there will be some differences from the plan. As the saying goes, the plan is not a change. You have to check the position of the Milky Way according to the situation on the ground. Star map software will be very practical. .

Remember to change the mode to ar mode in the App settings, so that when you turn the phone, the starry sky will also turn. The finished product of

is as follows:
