Palouse light pollution project

my picture

In conjunction with members of the Palouse Astronomical Society, I plan to use a narrow-aperture Sky Quality Meter (model SQM-L) from Unihedron.com to map out the sky brightness on the Palouse.

All data is from either my phone app (Night Sky Tools for Android) or from USNO Astronomical Applications pages, or occasionally from Stellarium desktop planetarium software.

An example database entry is given below.
