I couldn't decide if I really liked any of these pictures but I decided I would put them all on as one as it was supposed to be my first real attempt at a star trail. As you can see though clouds started moving in on me. I had already relocated once, from Lake Tekapo because of the clouds and I didn't have time to move again. I will definitely being going back to Lake Tekapo though to try again there, it's nearly a 3 hour drive each way but it should be worth it.
30 second, f3.5 iso 1600 single exposure from the 35 that make up the next picture.
35 pictures as above stitched together. The trails at the bottom have become broken by the clouds.
215 seconds f3.5 iso 1600 single exposure. This was a bit of a test shot to get short trails.
