Help us develop a

Sidewalk Star Field Guide!

Light pollution often deters would-be stargazers from seeing many of the objects shining above them. Many people aren't even aware of planets visible to the naked eye, or the constellations surrounding them, simply because they live in a place where it is difficult to see the sky at all.
We want to help people learn what's up there, even if they live in a light-polluted area. But first, we need YOUR help. No expensive equipment or telescopes necessary! Just you, your night sky, and your phone.
Here's what you can do:
We are in need of a range of images, from the darkest skies possible, to the middle of a city. This variety will only enhance the quality of information we hope to provide.
Please send your night sky images to: Be sure to include your location, date the image was taken, and the approximate time it was taken.
The field guide will be published in mid to late Spring 2020 (April to June).
Example of a sky that is ~70% dark, taken by Alex Martin using a Samsung Galaxy S10 outside Lakewood Ranch, Florida, at 4:30am on September 2, 2019. Looking east, the Cassiopeia constellation is visible at the bottom in the shape of an M. The Pegasus constellation runs across the very top of the image. The left three stars of Cassiopeia form an arrow that points upward at the Andromeda Galaxy a faint smudge of light to the left of another dim star near Pegasus.
Example of a sky that is ~15% dark, taken by Alex Martin on the night of September 3, 2019 at 10:30pm using a Samsung Galaxy S10 outside Lakewood Ranch, Florida. Looking north, the Big Dipper is clearly visible. One star of the Little Dipper is visible above the cloud, and the bright star Arcturus is visible at the very left of the image.
