Here is another photo from our night sky shoot at Lake Leschenaultia on Saturday night. This photo was created by stacking 119 photos, and each of those photos was a 30 second exposure.
I used my Phottix Aion intervalometer to trigger the camera, and had to clean up a few of the frames, due to some random stranger on the other side of the lake shining his torch directly at us.
