Galactic Center Rising

A shift in time can shift our perspective, which is why time lapse photography can be so powerful. Here is a simple time lapse of the night sky, using a wide-angle lens. You get a Big Here/Long Now experience.

But the Canon 5D used to capture this was modified by replacing the standard infrared filter normally ship inside the camera (which also block out the deep reds) with a special filter to permit near infrared photography. Thus the reds you see here that most cameras won't capture.  You can buy fully modified Canon 5D cameras, ready for astrophotography, from here.

Here are the technical specifics by William Castleman:

The time-lapse sequence was taken with the simplest equipment that I brought to the star party. I put the Canon EOS-5D (AA screen modified to record hydrogen alpha at 656 nm) with an EF 15mm f/2.8 lens on a weighted tripod. Exposures were 20 seconds at f/2.8 ISO 1600 followed by 40 second interval. Exposures were controlled by an interval timer shutter release (Canon TC80N3). Power was provided by a Hutech EOS203 12v power adapter run off a 12v deep cycle battery. Large jpg files shot in custom white balance were batch processed in Photoshop (levels, curves, contrast, Noise Ninja noise reduction, resize) and assembled in Quicktime Pro. Editing/assembly was with Sony Vegas Movie Studio 9.
