What the Clouds do at Night

I took about 700 images for this time lapse sequence. I wanted to capture the clouds at night. There were several ways I could have done the procedure. I could've gone for a low ISO and an long exposure or a high ISO and a short exposure. Always with higher ISO you have more noise. For the Saddle Rock sequence I chose an ISO of 2000 and for the Southern stars sequence I used an ISO of 1600 because the bright moon was in the frame. The exposure was 2.5 seconds with and interval of 5 seconds between shots.
