Data Logging SQM
« on: Oct 17, 2017, 23:29:33 »
I've got a new toy - a data logging Sky Quality Meter.

Last night was too windy for imaging and the transparency was poor (Sahara sand and Iberian smoke) but I left the meter running all night with a dew band to prevent it misting up:



The blip in the curve at 20:30 was caused by a cloud.  Probably the same thing happened at 3:45am.

It's this version:
https://www.firstlightoptics.com/unihedron-sky-quality-meters/unihedron-sqm-lu-dl-sky-quality-meter-with-usb-and-data-logging.html

But it is designed for continuous logging - it doesn't have a visible display like the standard model has.

Here's the standard hand-held one with a visible display but without data logging:
