I spent last week at an electronics Conference in Athens, Greece.
Amazingly, from the Acropolis I could see two observatories – one actually down in the town (!) and another far away on a hilltop overlooking Athens. I don’t think their light pollution can be too good! The Conference dinner was over on the coast a few km from Piraeus – once again, the light pollution was pretty huge, Jupiter clearly visible over the sea, the summer triangle getter much dimmer overhead, and the plough practically wiped out inland. It’s a great shame that the opportunity for great clear skies and good seeing conditions are so severely hampered by light pollution in Greece and on her islands.
