Here is an excellent map showing the light pollution levels across our beautiful planet, Earth. MAP Link.

Bortle Scale. The level of light pollution in a certain area can be measured on a scale ranging from 1 to 9 which is known as the Bortle scale. Use the slider above to gradually change the image from an inner city skyscape suffering from severe light pollution, to a pristine dark sky site.

Google recently announced a massive price increase for users of their maps API. If you’ve recently seen errors while trying to use the light pollution map, that’s why. I used to like Google To facilitate learning and using the scale, I've adapted Bortle's indicators of sky brightness as a table (below), including the color codes used in available light pollution maps. For the amateur astronomer, the most robust and convenient relative measure of sky brightness is the naked eye or telescopic limiting magnitude.

The Bortle scale is a nine-level numeric scale that measures the night sky's brightness.

The state parks are listed below, followed by a Bortle Scale Rating from one to nine. The scale rates the darkness of the sky based on a given number of celestial objects that can be seen in the sky. The lower the number the darker the skies. The information below came from Texas Parks and Wildlife. A map to the parks is located here.
