partial solar eclipse

Yesterday afternoon there was a partial solar eclipse visible from here in New Zealand. The weather cooperated and it was a bright sunny day. I brought out my telescope and solar filter, sat out in the sun, and took a few dozen pictures. Only after I had finished taking pictures did I have the idea of composing a video from the frames.

First, I took the timestamps from each of the photos I took and determined the best-fit interval that would give me approximately equal spacing between images used for frames. Then, I wrote some image processing that automatically cropped and centered each image. Finally, I used iMovie to take the sequence of images and compose a video which I uploaded to YouTube. Here is the final result.
