Maybe you admired the dark sky in a place with low light pollution. You can see more stars in the sky, but when you look in a city where there are more lights, you can see just few stars.

If you look carefully, in a place where there's less light pollution, you can even see the Milky Way.
Unfortunately, there are people who live in big cities that have never seen a whitish trail in the sky: the Milky Way.
In order to determine the level of light pollution of your city, you must follow these steps:

4. Appreciate magnitude of the sky
5. Send your observation data.
