Sky Quality Meter-LU-DL

An affordable USB-meter for continual, connected measuring sky brightness for astronomers! Can work autonomously. The "Sky Quality Meter-LU-DL" measures the brightness of the night sky in magnitudes per square arcsecond with unprecedented sensitivity in a handheld meter!

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.
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.
CCD users can make a correlation between the SQM reading and when the background reaches some ADC level.

Features

Sky brightness displayed in visual magnitudes per square arcsecond.
Infrared blocking filter restricts measurement to visual bandpass.
Temperature in both Celsius and Fahrenheit as well as model number and serial number can be displayed with different button press sequence.
Precision readings at even the darkest sites.
Field-upgradeable firmware
Open protocol document.
USB connectivity
Included applications for reading data in Perl.
The Half Width Half Maximum (HWHM) of the angular sensitivity is ~10°.
The sensitivity to a point source ~19° off-axis is a factor of 10 lower than on-axis.
Maximum light sampling time: 80 seconds.
Minimum light sampling time: 1 seconds.
