In that sense artificial LP is *always* and you have to travel further and further to evade that.
DARK MOONLIGHT OR BRIGHT MOONLIGHT VS KILLER FULL
NO: It is natural and belongs to nature and has its charm and the nice full moon nights with the blue skies (I call them 'blue moon') and only a few days a month. Despite this I managed to picture once the LMC on a full moon night with a UHC filter, but LMC is such a bright object. YES: the Full Moon is even worse than most inner city LP: it is Bortle 8, even at the darkest locations and harder to filter out than artificial LP, because it is full spectrum, including scattered blue, worse than 5000K LED. If it's bad enough to render a dark sky site useless (effectively making it similar to a light polluted sky, rendering the trip to such site pointless), it might not be light pollution per se, but its effects are exactly the same (if not worse). It is natural light, but sometimes it's much worse than artificial lights. And it's way worse than some neighbouring lights, becase it affects very large regions of the sky, while streetlights only have a very local effect. Since the clear sky lottery doesn't care about the Moon phase - and actually, more often than not, the miraculous clear sky night(s) fall close to the full Moon - to the poor amateur astronomer trying to do visual or astrophotography during that miraculous clear sky night, moonlight is preventing him/her to do that in an optimal way. I am not debating if the Moon is necessary for survival of life on Earth (or even initial life development, for that matter).Īnd wether the albedo of the Moon is low or not, it's still high enough to decrease someone's sky limit magnitude by significant amounts, depending on height and phase.
