    :coold: I wonder if that's a composite though? Otherwise he'd need the camera on a base that would move with the stars... blurring the arch. :hs:

    Still... :coold:

    thats like a 15 minute exposure of the milky way.. it would be a LOT more blurred than that....

    That looks like one of the arches from Arches national Park in Utah photoshoped in.

    Image information:
    Capture Time: 2006:11:15 21:20:16
    Camera Model: EOS-1D Mark II N
    Type: CR2 Image
    Size: 6.9 MB
    ISO speed: 640
    Exposure time: 712/10 sec
    Aperture: f 3.5
    Focal length: 15 mm

    I guess he took a 1 mil spot light and shined it on the ground so it would reflect the light to the arches, making the glow rather then a harsh light look....

    I suppose a 71s exposure would work and explain the slight blurring of the stars, and if he just turned on the spot towards the end it'd be okay. :dunno:

    Still. Very :cool:

    hmm i guess.. when i do a 30 second exposure however, the stars are like half centimeter streaks.. so he had to have some sort of mechanized following thing

    hmm maybe he was pointed at polaris. so its like a spot with the streaks a lot less than normal because its rotating around that spot rather than being some huge streaked spot of the sky

    For 71 seconds of exposure, those stars do not look very blurred to me.

    I also don't see how that could have been shot at 3.5 It's clearly at infinity focus.

    15mm is pretty wide though. I guess he was using the Sigma 15-30 3.5 - ?.? wide open.

    I guess when you're that wide, star trails are reduced and DoF is great enough to where the arch is still in focus (maybe it's a very high arch as well).

    the star trails seem more noticeable towards the edge of the picture
