This Video was achived by "stacking" image sequences provided by NASA from the Crew at International Space Station (see also fragileoasis.org/blog/2012/3/on-the-trails-of-stars/). These "stacks" create the Star Trails, but furthermore make interesting patterns visible. For example lightning corridors within clouds, but they also show occasional satellite tracks (or Iridium Flashes) as well as meteors - patterns that interrupt the main Star Trails, and thus are immediately visible.
The many oversaturated hot pixels in some of the scenes are the inevitable result of ultrahigh ISO settings the Nikon D3s in ISS-use are pushed to for keeping exposure times short by all means (owed to the dramatic speed the ISS travels). As there are no dark frames or RAW data currently available, hot pixels are not easy to remove.
After the initial stacking, all images have been sequenced with Apple Motion and the Video cut and edited with Final Cut Pro X. Stacking done with StarStaX, get it here: markus-enzweiler.de/software/software.html
This Video would also not have been possible without that great minimal soundtrack "Eileen" by Lee Rosevere (members.shaw.ca/happypuppyrecords/index.html) that totally nailed the mood, as well as a short clip of "Window #3" by Two Bicycles (freemusicarchive.org/music/Two_Bicycles/Beko_Crash_Symbols_1/07_Window_3). VIMEO MUSIC STORE ROCKS!

Thanks a lot to my favourite bad Astronomer, Phil Plait at BadAstronomy for first posting the film (blogs.discovermagazine.com/badastronomy/2012/10/16/my-god-its-full-of-star-trails/) and many many thanks to Vimeo for the Staff Pick!
A truckload of thanks go out to NASA astronaut Don Pettit (petapixel.com/2012/06/25/astronaut-don-pettit-floating-with-his-huge-camera-collection-on-the-iss/) and his colleagues for taking these images, and making films like this one reality!
Finally, please also be aware of the growing issue of light pollution (plightwithlight.org/index.php?id=49&L=1) one can see in many of these scenes! Support IDA (darksky.org) on their challenge to preserve the night sky for us and our children, on reducing energy waste! And don't forget, it is your tax money that lights up the sky!
Oh, and visit my friends at the UNESCO Project TWAN (twanight.org) for some of the coolest nightsky images and videos on our planet! One people, one sky!
Always believe in your dreams and make it possible!
All the best,
Christoph Malin
