The Aurora Star Lapse Experiment

 

The Upper Peninsula is truly magical, and the fact that you can see the aurora, with a little research is mindblowing. This shot was taken at a road-side turnout east of Marquette (Marquette has a bit of light pollution) right around the Deerton area. 

 The Idea with this shot was to capture the blur of the stars as the earth rotated during a period of about 2 hours. I recently purchased a very very wide lens, the Rokinon 14mm F2.8, and this was my first time using it. There are a few different ways that you can pull this shot off, some better than others. One way of doing it, is to keep the shutter open for the full two hours. I don't recommend this as it can lead to a very hot sensor, and an over-accumulation of noise; not to mention, your almost guaranteed to under or over expose. It's extremely easy to blow-out the aurora during a long exposure, and this is almost guaranteed if your exposure is too long. 

I Iwill be posting a full tutorial on the specific techniques I used along with the post processing involved.
