Today, we are using digital camera which is so much better. However, we can't do just one long exposure as with film. Electronic noise does not allow us to do very long exposure. On top of that light pollution will contribute to fill out a bright sky.

If one tries a long exposure of a few hours, he would get something like that, hence a completely saturated image.

Instead of that, we do short (<1 minute) exposure and we then co-added them altogether.
