Here in England light pollution is becoming a problem to astronomers and torchaholics alike!
I find that in high light pollution areas in rural settings I have to use a more powerful torch than I would in a low light pollution area!
The stark difference of the darkness in Snowdonia compared to the orange skies of the Midlands made me able to benefit from single-LED torches where I would use a Luxeon 5W in polluted areas.
Has anyone seen the pictures publised in Saturday's "Daily Mail"?
This is a result of councils using bigger bulbs in taller lamp posts and more bulbs than ever before. Also, the change frtom Low pressure Sodium to High pressure Sodium bulbs means that the pollution is spread over a wider spectrum!
Is it the same in urban areas of America or other countries?
