Quote:I'd love to see the growth in some of the major metro areas of the U.S. That would show another way of looking at the impact of growth on local light pollution.
Tony Flanders First and foremost observing love: naked eye. Second, binoculars. Last but not least, telescopes. And I sometimes dabble with cameras.

Never argue with a fool.Onlookers often can't tell the difference.
Quote:And this exponential growth of urban sprawl is precisely why light pollution regulations and measures can never hope to more than somewhat slow spreading light pollution. For anyone who has been in the hobby for a really long time, their observation of worsening conditions illustrate that the loss of dark skies overall, as well as the distance at which light sources can significantly impact the sky brightness, is far beyond any hope of real control. The only exception to this being perhaps in those areas undesirable for human habitation and industry.
Quote:Hermit, your outlook on the future is, in my opinion; far rosier than what is self evident where ever I travel in the U.S.
Quote:Tony, if you think that light pollution hasn't changed much everywhere in this country over the past three decades, I know for a fact that you are very much mistaken.
Quote:The U.S. has reached a point where every little farm yard even has outdoor floodlighting.
Quote:One can see clear evidence of the great metropolis of the NYC area at up to 150 miles out of the city today. In New England, save for the extreme north just a little short of the border, vitually all locations today are impacted to some degree by light pollution.
Quote:Your status as a casual observer is hardly critical enough to establish any sort of baseline for a critical comparison.
Quote:At the same time, in my experience so-called dark sky meters do not necessarily reflect what the observer's eye perceives. I've seen some absurd claims made for sky measurements taken at sites (like Stellafane) in New England that supposedly rival those obtained at remote professional observatories. Having visited both, the story told by sky meter readings becomes questionable, at best.
Quote:I appreciate that your job at Sky hinges on promoting the hobby and acknowledgement that the situation is not good and obviously worsening steadily ...

Quote:By that time Brattleboro far to the south was clearly apparent from the new campgrounds.
Quote:Today, unless the village is shrouded in ground fog, its light dome diffuses somewhere into the western sky and there is minor interference all around.
Quote:I've noticed how dark it is when you're out on the water - in the Gulf, one of the Great Lakes, the Baltic (not during the summer of course), the Mediterranean. OK, the Mediterranian wasn't so dark where I was, but maybe there are dark parts.
