The central cross marks the location of the Ottawa clear sky chart.

Light scattered through the atmosphere brightens the night sky, causing stars and faint objects to be rendered invisible due to the reduced contrast. Light pollution also prevents the human eye from fully dark-adapting and reaching its maximum sensitivity. Sometimes, the more light there is at night, the less we can see.
