I have been experimenting with Time Lapse photography here are some of my examples.
The below exposure started at around 11:00 PM and continued for about the next fours hours. One shot was taken every 15 seconds to produce 1021 images then imported into Adobe Lightroom and exported to LRTimelapse to produce the final video at 24 frames per second.
Another attemp I started at 1:30 AM but its short as the camera stopped taking images (only 67 every 15 seconds) after about 17 minutes as the external battery unexpectidly ran out.
