Q:   How can I tell how bad my skies are?
A: Sky glow is a major problem--roughtly two-thirds of those in the USA cannot see the Milky Way because of light pollution.

How bad (or good) is your sky? You have a few options for determining the answer to this question.

You can check out the light pollution maps available from Attilla Danko's Clear Sky Clocks system. Click the bar graph next to an observatory near you. Under the graphic will be a link for a light pollution map, which will estimate your sky brightness.

You could use the Sky Quality Meter from Unihedron to measure your sky brightness.

You could do a star count.

There's even more information on the IDA's Measuring Light Pollution page.
