I need to get out of the city!

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.

The stock anti-alias (AA) filter blocks a range of red wavelengths so the camera will render desireable skin tones. 656 nm is one of those wavelengths that also is emitted by emission nebula (star forming gas nebula). The replacement filter permits passage of 656 nm so that emission nebula can be recorded.
Star and Flagged, 1 word Amazing!!!!
Just one extra thought though,.
Mayan Calander ends at 21 / 12 / 2012 They seemed to have significance to this, i wonder what this view of the stars looked like back in their day? and why did there mathamatical calculations seem to end on this date? im still trying to work it out. Because there maths for their calander evolved around sites like this. Great find..
Jenkins suggests that the Maya based their calendar on observations of the "dark rift", a band of black dust clouds in the Milky Way, which the Maya called the Xibalba be or Black Road. Jenkins claims that the Maya were aware of where the ecliptic intersected the Black Road and gave this position in the sky a special significance in their cosmology. According to the theory, the Sun precisely aligns with this intersection point at the winter solstice of 2012. Jenkins is credited with the premise that the classical Mayans anticipated this conjunction and celebrated it as the harbinger of a profound spiritual transition for mankind.New Age proponents of the galactic alignment theory argue that, just as astrology uses the positions of stars and planets to predict the future, the Mayans plotted their calendars with the objective of preparing for significant world events.
Critics suggest that fears about 2012 should be tempered by the fact that the alignment in question takes place over a 36-year period, corresponding to the diameter of the Sun, with the most precise convergence having already occurred without incident in 1998 Also, Jenkins himself notes that there is no concrete evidence that the Maya were aware of precession.
