Yes, it was done with a Nikon D700 and the kit 24-120mm lens. It has a feature Nikon calls an "intervalometer" which you can easily set to automatically take photos at whatever interval you program it to. No additional hardware is needed. I set the camera on a tripod and went to sleep, it did the rest. I mashed the resulting series of photos into a short video using Windows Movie Maker.
The camera has some features I really loved, other than the intervalometer. One that I used all of the time was the artificial horizon. You can check if the camera is level through the viewfinder, on the top LCD or superimposed on the image in Live View. I had a real problem with needing to rotate and crop my photos before, not so with this camera. I programmed the DOF preview button to control this function, since if I am worried about the depth of field of a digital image I just snap a photo and look at the LCD.
Another is the Auto ISO function. The camera adjusts whatever maximum ISO and minimum shutter speed you choose so you can shoot handheld and not get motion blur.
I returned the camera. I was disappointed with the sharpness of the images, as well as very noticeable falloff in the corners of the frame. It had a tendency to make large, green lens flares across the image whenever the sun was shining on the front element. Poking around the internet I found a guy who put that lens on his
10 Worst Nikon Lens list. I may give FX another chance, as soon as I figure out what lenses I would need to get my money's worth out of the full frame sensor. My wish list looks prohibitively expensive: a D700 body, 70-200mm f/2.8D G-AFS, 17-35mm f/2.8D, 50mm f/1.8D & SB-600 Speedlight come to $5900.

Last weekend I shot some jeepin photos with my old Olympus point-n-shoot and hated the experience. I'm definitely getting another DSLR, it is just a matter of figuring out what I can afford to use
as a complete system. My favorite shooting is done in the low light conditions for which there is no substitute for a larger sensor.
Here's some more from the Nikon:

The Milky Way
Comb Ridge and Valley of the Gods, seen from Moki Dugway. This also features the giant size version of the Ugly Green Lens Flare. It usually presents as a series of much smaller green circles.
