Sky glow, mostly caused by big cities, makes it hard to see dim objects in the sky at night, such as nebulae, stars and galaxies. Sky glow reduces the contrast between the sky and between the stars and galaxies, which makes it even harder to see dim objects. Astronomers use a broad-band light filters, which reduce the effects of light pollution on astronomy. The broad-band light filters do that by filtering out spectral lines and so alter the view of dim objects. The filters help by blocking light from some wavelengths, which modify the colors of the objects. But the broad-band filters can only affect certain object types. They affect nebulae, but have little effect on galaxies and stars.

Causes light pollution, light pollution is pollution caused by misplaced artificial light and reflections such as outdoor light which scatters in the atmosphere and reflects back to the ground. The light allows a fraction of light to go up in the sky.
