Night sky

So, this is my first attempt at merging photos together to get a star trail. Ideally I would have liked something else in the frame to give it a bit of perspective, but you don't tend to find much in the middle of a field! Also, next time I will do it for longer. I took about 24 images at 30 seconds each. (But as it was nearing midnight and the temperature was -4, I decided to pack it in and see what I got)
