    I was thinking this at first but in the composite,
    (how was this composite made? was it by stacking image
    after image with exactly the same scale and
    orientation so that all the stars would match up?) you
    can see just to the upper left of each green object a
    small white object. A booster venting? But it's moving
    in an odd direction. Like Jim said, your friend should
    go out tonight and take the same image.
