This was created in LR and LRTimelapse. It's comprised of 396 individual images shot at 30s+ intervals. I used a Canon intervalometer set at 1s. The Canon intervalometer waits for the shutter to close and (I think) the disk write to complete before it trips the shutter hence the + at the end of the shutter speed. As in the prior video, passing traffic wreaked havoc on the image. To me it looks like lightning flashes but I would have preferred a completely dark site.
