The SQM-LE sky quality meter has a lens and an Ethernet connection. You connect it to your network and let the brightness of the night sky be measured automatically, all night long, and read out on a computer.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Interesting for <a href=\"https:\/\/www.telescoop.nl\/en\/observatories\/\">Astronomers in the Netherlands<\/a>, nature reserves and anyone who wants to build up a long series of measurements. It is also a nice project for a school; check that out as well. <a href=\"https:\/\/www.telescoop.nl\/en\/schools\/\">Our offer for schools<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You need a network cable to the measuring point, and outside the meter should be housed in a weatherproof enclosure. Think ahead about where you will store the data so that you can compare the measurement series over months.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you also want to perform separate
