    I couldn't understand the title of the thread and just skipped over it the first time.

    Have nothing to say about the picture.

    theres a reason why most of the more dramatic star trails are taken in the country. city lights tend to drown out all but the brightest stars, PLUS the smog makes it even worse.

    Camera Make: Canon
    Camera Model: Canon EOS DIGITAL REBEL XSi
    Image Date: 2009:01:04 19:26:51
    Flash Used: No
    Focal Length: 48.0mm
    CCD Width: NaNmm
    Exposure Time: 601.000 s
    Aperture: f/32.0
    ISO equiv: 100
    White Balance: Auto

    Should have gone with a wider aperture (say around f/4, f/5.6) and higher ISO(400ish), and maybe a wider lens too.

    Huh? He's not trying to get a quick exposure out of it. The intent is to drag the shutter so you can get trails from the stars in the sky, thus the F32/10min shutter. And the focal length of the lens wouldn't have anything to do with the exposure anyways.

    And why did you drag up this old thread anyways?

    I wouldn't consider 4 months old.

    But the OP got no star trails because there was way to much ambient light and the aperture should have been f/11, f/16. The bright streak isn't even a star trail, it's probably a meteor trail (notice it's a straight line, not an arc).

    I am surprised noone else mentioned this.. there are blinding bright lights shining into your lens! As in park lights. Try going in a dark place and taking a photo of the sky without any earth lights, the moon or other nonsense in front of your camera. Try it with your Sigma wide :).
