    I asked for images by photographers from all over the world. I sent out the task for volunteers to capture the light pollution from any major city.

    To try to keep an even playing field, the following capture parameters were stipulated:

    I did allow a couple of compromises, as some very kind offers came in from people who could not quite comply to one or two factors. That being said, it is still closely controlled to keep the results comparable.

    Canon EOS 400D (Rebel) DSLR
    18-55mm Lens
    Tripod mounted (no Tracking)
    Full aperture (F/3.5)
    Full zoom out (18mm)
    ISO 800
    30 Seconds
    No stacking or photo enhancing
    NO MOON! NO CLOUDS!

    Photograph the greatest concentration of stars visible from location as seen from within a 30 KM radius of the city centre.
    More photos are due in soon so keep watching!

    If you own a Canon EOS 400D Digital SLR (or Rebel XTI) camera and would like to contribute an image from your city, follow the capture instructions above and send them to [email protected]

    Because from lots of experience at astrophotography, 800 is a good median speed to capture a bit of detail from the milky way in 30 seconds if you can see it at all.

    400 doesn't pick up enough and 1600 is too noisy. I want no ICNR or any other processing done. Just raw images straight from the camera.

    I also had to attempt to control as many settings as possible to keep all the submissions fair and comparable.

    Yes, that will do just fine guys. Please, just stick as closely as possible to the parameters I have set. Aperture, ISO, shutter, visibility etc. NO Moon NO clouds.
