On Thursday night when the sky was clear, the Milky Way looked lovely setting over the mountain in the West. So on Friday night, 16th October at IISAC2009, I setup my Canon 20D and 24-105mm L lens on a tripod, and programmed it to take 30 seconds exposures on repeat.
I combined the result into a timelapse movie. There’s also a single star trails image with all of the frames combined.

The single star trails image is below. Click the image for a larger resolution (1200px) version.

The shots were taken with my Canon 20D and 24-105mm L series lens, sitting on a fixed tripod. The lens was set at 26mm, f/4, and the camera was taking 30 second exposures at ISO1600 – on repeat, for 284 exposures.
The raw frames had some minor processing in Raw Shooter Premium, before being saved as large jpeg. The large jpegs were batch processed in Photoshop to apply noise reduction, saved as large jpegs for the single star trails shot, and then had some saturation boost, curves adjustment and resized to 800px wide, canvas height extended to 600px and the tag line added, and then saved a second time – the small jpegs to be used for the time lapse.
For the still image, the large jpegs were loaded into startrails.de and the star trails image was created. I used Photoshop for saturation increase, curves and levels.
For the time lapse, the small jpegs were loaded into startrails.de and processed using the Movie icon – saved using the xvid codec.
Thanks for looking.
