Sky Quality Meter Unihedron SQM-L

Sky Quality Meter Unihedron SQM-L

With the Sky Quality Meter you can evaluate the clarity of the sky background. This small instrument is lightweight and so easy to carry that it fits in any pocket. Thanks to it, you can easily compare the different observation points where you want to work and find the perfect place to make your night observations.

When we have to select our observation place, depending on our personal characteristics, many times it will be difficult to distinguish the best sky between two different locations.

In Telescopiomania we recommend the Sky Quality Meter Sky Quality Meter as it is a tool that will allow us to make this decision objectively.

The Sky Quality Meter SQM-L is, in fact, a photometric instrument. By means of an integrated diode, it has the ability to measure the clarity of the sky and display it in a quantified way with numbers on the device's screen. By pressing the red button, the SQM-L starts measuring the brightness. It takes 8 seconds. The photometric measurement range is only in the visible light width of the spectrum. In addition, it measures the temperature in degrees Celcius and Fahrenheit.

Apart from measuring the brightness of the night sky for astronomical observation, the SQM has many other applications (time evolution of light pollution at a certain location).

General characteristics:

• Easy to transport.
• Dimensions 95mm x 60mm x 25mm (without button).
• Objective measurement of the brightness of the sky.
• Temperature measurement in degrees Celsius and Fahrenheit.
• 9V battery included.
• Made in Canada.

Model SQM-L:

The SQM-L model incorporates an integrated lens that provides a localized measurement range of 20°. Thus, it is possible to measure even the smallest areas of the sky with great accuracy. In this way you are able to appreciate the difference in clarity between the horizon and the zenith and in different directions.
