All Sky Cameras - An Educational Tool
-
All sky cameras point upward and use a fisheye lens to capture a picture of the sky - night or day
-
A graphical overlay names the stars, planets and constellations in the current view overhead
-
The graphical overlay shows where the stars and constellations would be seen if there was no light pollution
-
In areas with light pollution, any clouds reflect that pollution downward, increasing the impact of the escaping light
-
In areas with natural, pristine skies, any clouds appear dark and hide the stars, reducing the light coming downward
-
Automated all sky cameras run 24 hours a day and provide summary movies and images online each morning
-
All sky cameras are entertaining and help us to recognize the presence of light pollution in our local skies
-
All sky cameras are an educational tool - on light pollution, on astronomy and meteorology too!
