He explains how he did it in the comments...

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.

Opinion = fact. Anecdote = proof. Political label more important than either of those.

Yep.

I always found it odd that our eyes never sees the core but a camera will.

We can see the general glow of the galactic disc, but that's about it. You really need to be out away from any city light contamination to see it, too.

The biggest issue is that most of our low-light sensitive bits are in the areas away from the center of the retina. There's also less detail-oriented bits in those areas. Combined, they give us fairly crappy detail in low light conditions.

Also, much of the light is not in the visible spectrum of light, which is why he had to modify his camera happy

Ahhh, yes, this would explain most of it.
