Time Lapse of Galactic Center of Milky Way rising over Texas Star Party

Galactic Center of Milky Way Rises over Texas Star Party from William Castleman.
According to 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.

Impressing work.
To make timelapse videos, I use the free tool Icarus Camera Control on my Mac, ImageMagick command line tools and ffmpeg to create the video. You just have to pay for a good camera ...
Any chance of downloadable video in higher quality? Still quite a few compression artifacts in the HD version in vimeo.
I would love to see this in higher quality, any chance of a less compressed download? It seems even HD vimeo has quite a few compression artifacts.
What I love so much about this is that this *isn't* the result spending millions of dollars and high-end telescopes kitted out with specialized gear. Sure, the camera and lens aren't exactly something you'd pick up at the drug store (looks like about $2,000 for the pair) but it's a remarkably small investment for such a spectacular result.
And of course cameras costing much less can still be used for time lapse projects like this. Hopefully lots of people will be inspired to come up with their own time-lapse movies. It's easy and fun!
Seeing the night sky (and space) throught this super short focal length lens made me realize that people who look to space, feel trapped on earth.
Beautiful !
I want to go and have a go myself !
But: can you shed some light on your comment : (AA screen modified to record hydrogen alpha at 656 nm): what would a DIY meaning to this be; without butchering my camera... ? can one achieve this by: judicious use of white balance/ [e.g. photoshop post processing... ? and how would I go about it... ?]
Thanks!
@Erinski Easy, you couldn't be more correct or wrong. I wouldn't say trapped but I do feel this overwhelming urge to map every star and understand the function of everything within our physical universe. This is the same urge that prompted man to cross vast waste lands, conquer sea and sky, bringing along innovation that betters his race.. and now the last physical forray into space.
@Anthony Alexander I second your setiment, but add that some of that human innovation has become a stumbling block to seeing those night skies. Light Pollution blocks the view of millions of us earth-bound humans. There are initiatives in several places that would make use of better lighting and lessen the amount of light going skyward. These movements should be supported whenever possible.

Hi,
Great timelapse, truly stunning. I'm curious about the modification you've done to your camera to record light at 656nm - this falls within the normal visible light spectrum doesn't it? Would the camera not normally record light at this wavelength? What effect has this modification on the recorded images, does the entire spectrum shift or are you simply not filtering a wavelength that would normally be filtered by the camera? Is the modification something that you can buy or was it something you've improvised yourself?
I have had a go at time-lapse photography myself although in my case it's of clouds and not stars:
