Item No. 787-11000
Manuf. No. Unihedron SQM-LE

An ethernet-enabled SQM model for night-time sky brightness monitoring!

An affordable meter for continual, connected measuring of sky brightness for astronomers!

The Sky Quality Meter - LE measures the brightness of the night sky in magnitudes per square arcsecond.

Designed by Dr. Doug Welch and Anthony Tekatch

Uses:

* Find out how good the night or site REALLY is.
* Compare the sky brightness at different sites quantitatively.
* Document the evolution of light pollution in your area.
* Set planetarium dome illumination to mimic the skies people are likely to experience elsewhere in the city.
* Monitor sky brightness through the night, night-to-night, and year-to-year.
* Determine which nights show the greatest promise for finding the “faintest fuzzies”.
* Calibrate the effect of sky brightness on qualitative measures such as the Bortle Scale.
* Investigate how sky brightness correlates with the solar cycle and month-to-month sunspot activity.
* Help provide local ground truth for future sky brightness prediction with the Clear Sky Clock.
* CCD users can make a correlation between the SQM reading and when the background reaches some ADC level.
