De-Rotated Eclipse Animation

This video contains an animation of 617 frames of images from my Canon 450D on the AstroTech AT-80LE, taken at 100 ISO and 1/1000 second shutter speed. That's about three and a half hours of duration, and at ten frames per second this one minute video is running at about 200x the actual event. These images have been position aligned and de-rotated to eliminate the field rotation effects of the alt-az mount of the NexStar. There are a couple of hazy spots prior to totality, with more clouds afterwards, but generally these frames look great. I wonder how much of the latter was due to the eclipse itself causing a drop in temperature and condensing more of the humidity into clouds.
