Jodrell Bank light pollution simulation - can I expect that in the real sky?
Recently I visited JB's Science Centre, where they have regular Planetarium shows. At the start of the show, a light-polluted sky of Chesire was simulated. It was a very dramatic moment to see this change to a completely dark sky with no light pollution. But I'm wondering, was this merely a dramatised exaggeration, or could I really expect a non-polluted sky to be such a vast improvement as demonstrated? The answer is pivotal as to whether I learn to drive (I'm 17 next month) to be able to take my 15 cm Newtonian to a dark site, or instead I invest the money in a larger telescope in order to "beat" the light pollution in the back yard. Comments, opinions would be greatly appreciated... |

Dear peter,
In a dark sky, you will see with your unaided eye--more than 6000 stars, and the milky way. Learn to drive. best Penny Message-id: |

In the entire sky there are something like 6500 "naked eye" stars. Given the fact that you can only see half the sky at any one time, and that atmospheric extinction wipes out faint stars close to the horizon, I doubt that you could ever see more than, perhaps, 2000-2500 stars at any given time in even the darkest of skies! Where do you get your figure of 6000 from? Curiously, Chris |

But I'm wondering, was this merely a dramatised exaggeration, or could I really expect a non-polluted sky to be such a vast improvement as demonstrated? I live only a few miles from JB (although much closer to Manchester and the Airport), and I'd say the difference when I look in my back garden is very dramatic to when I visit dark sites in North Wales. I have heard that the visitor centre at Jodrell Bank is to be demolished in the very near future. Is this true? The answer is pivotal as to whether I learn to drive (I'm 17 next month) to be able to take my 15 cm Newtonian to a dark site, or instead I invest the money in a larger telescope in order to "beat" the light pollution in the back yard. I learned to drive a couple of years ago (I'm now 19), and I've found the skill very useful for other things than astronomy. Ric |
