Spiral arms and bow waves

Back in October 2013 I recorded an RGB image sequence of the LMC at Wiruna, Central Tablelands (>1000 m ASL). The sky at Wiruna can sometimes be very dark, except toward the South East (Sydney).

Here are low-resolution super-stretched versions of the original images. These noisy images show the spiral arms nicely, as well as what I imagine to be bow waves of star formation triggered by the LMC ramming into the halo of neutral hydrogen gas, dust and other dark matter surrounding the Milky Way.

Technical Specs: Canon Astro 50D with EXcooler, ISO 3200, 25 x 4-minute exposures, 100 mm f/2 Lens set at f/5.6.
