The SpaceX Falcon 9 launch trajectory can be seen clearly in this composite of shots taken every 3 seconds with a fisheye lens. As mentioned previously, the white cloud is probably a vapor trail caused by passing through a layer of humid air, and the dark line running off to the right is a shadow cast by the cloud.

If you extrapolate the rising part of the trajectory, you'll be able to find the tiny crescent moon in the shot.
