This week in the Duluth/Superior area the local International Dark Sky chapter Starry Skies Lake Superior is hosting a week long event Celebrating the Night Sky Week. My photography has been used in a lot of the promotional materials and today was the all day seminar talking about light pollution, LED lighting technologies, affects on birds and human sleep patterns. There was a lot of interesting speakers and I definitely learned a lot about the LED issues and technologies. It was also very interesting hearing about the connections to the stars that the Native American tribes have. I was there as a participant taking it all in but I did still have my camera and took a few photos of the various speakers.
