Process:
1. a 300 frame, 16 bit video was taken every 4 minutes. Each frame was only 800 by 600 pixels in size.
2. This produced 44 separate video files.
3. Each file was processed using Autostakkert. Only 50 of the best frames were stacked and sharpened by Autostakkert. This produced 44 separate images.
4. Each image was processed in Astro Art.
a. an unsharp mask was applied to sharpen particular features of the prominence.
b. a Digital Development Processing filter was applied to darken just the background and the image of the full sun.
c. From the first image, the x &y coordinates of the prominence' base was determined.
d. For the remaining images, they were shifted accordingly so that their prominence base would match the base of the prominence for the first image.
Finally, all images were strung together into a single video file using RSpec.
