A star trail sequence shot at Patricia Lake in Jasper National Park, Alberta, showing two cameras at work shooting a time-lapse dolly motion control sequence (at left) and a static camera star trail sequence (at right). This is a stack of 100 frames out of 400 shot by the third camera, with one frame shot a couple of minutes after the sequence and layered in to add the blurry but point-like stars at the ends of the trails, including the Big Dipper. Each frame was 32 seconds at f/4.5 (stopped down too much by accident) with the 24mm lens at Canon 6D at ISO 800 in bright moonlight from the waxing gibbous Moon.

The aurora borealis in a mild display AUgust 26/27, 2014 as shot from Grasslands National Park in Saskatchewan. This is a single frame from a 200-frame time-lapse taken with the Canon 6D and Rokinon 14mm at f/2.8 and for 60 seconds at ISO 5000, making the bright parts of the display overexposed here (shortly after this, as the aurora brightened I cut back the exposure).
