Photometer Sky Quality Meter RS232 Version

Sky Quality Meter - Easy determination of the brightness of the night sky

Using the Sky Quality Meter, you can objectively determine the background brightness of the night sky in just a few seconds. This small device is lightweight and handy so that it fits into any pocket. You can easily compare different observing locations and find the best location for your astronomical observing.

An observer can only subjectively determine the limiting magnitude at an observing site. Experience, physical condition and eyesight can all influence the result. The Sky Quality Meter is completely independent of these factors.
