Are You Causing Light Pollution?
When I first arrived in Australia I lived in a rural area and I was struck by how impressive the stars looked at night.
Now I live in Melbourne the views aren’t quite as good.
A large part of the reason is lights shining upwards that illuminate specks of dust which make it hard to see the stars clearly and blocks out the fainter stars.
This slide shows the effects of various fitting and how to reduce light pollution.
