VARIOUS ASTROMICAL CONCERNS ... up<br />
1. Comparison between the importance <strong>of</strong> light pollution and aircraft contrails: "I've been hoping that what happened in Califonia (deregulation) wouldn't happen here<br />
(Missouri) because I'd be in a world <strong>of</strong> hurt for spare cash. Maybe it would be all for the better if that is the only way to get light pollution under control. Increased<br />
electric bills would be a real project killer, but I do already have several instruments to observe with. However, as my previously very dark rural location has become<br />
increasingly suburban, I've noticed that the biggest limitation is tropospheric transparency. From aircraft contrails at high altitudes (the worst source <strong>of</strong> obscuration), all<br />
the way down to diesel exhaust from several different truck stops, everything has gotten hazier. The closest truck stop is seven air miles distant and it only takes a few<br />
months to start turning my white dome black after it has been repainted. Additionally, that one truck stop throws out enough to produce its own glow, as seen from<br />
here": http://astro.umsystem.edu/... - and - "Light pollution has largely destroyed our visual and photographic view <strong>of</strong> the night sky and aircraft condensation trails are<br />
now destroying the daytime sky. One might have thought that light pollution would have been the greater problem, but electronic detection and processing methods have<br />
helped to mitigate the worst effects. I wonder what are the chances <strong>of</strong> a development to nullify the obscuring and sometimes turbulent effects <strong>of</strong> aircraft condensation<br />
trails on astronomical observation? These may yet turn out to be the more serious problem": http://www.google.com/...<br />
