Re: [APML] Photography From Orbit

Peter,

You made a very interesting observation. The more efficient cutoff lighting lights the ground rather than the sky. The space photographs show the area that is lit rather than the number of photons sprayed into the sky. Basically you can only rely on the space view to show areas where there are few people (who light up the area). For astrophotography, you need both dark and transparent skies. Space photos won't tell you much about transparency. Infrared imaging may show water vapor, so look at local weather satellite views. You will have to "go there" to check out the promising sites you find from space photos. I'm sorry I don't know a source for the photo coverage of your area.

Good luck finding a good spot,

Don

Hi All

The NASA night time image of London shows the light pollution from the London orbital motorway, the M25, as a long fine line circling the capital. Interestingly the motorway is most obvious on the image where the lighting is from full cut off anti light pollution fittings. Other sections of the motorway lit with "spray the light everywhere" fittings is hardly noticeable! Does anyone know if there are any other recent images of SE England taken from space so I can locate the best astrophotography site ?
