Swirling Stars

I haven't posted in a while since I haven't been taking that many photos (I have a cold :-S), and I would rather not dig into the archives just yet... I am getting better and finally got out to take some more night photos. I was experimenting with a super slow shutter speed. As you can see from the exif this one was 2033 seconds or 33.91 minutes long. I was surprised to find it had some light pollution, but shooting in RAW and Photoshop help a lot...
