Process:
1. a 300 frame, 8 bit video was taken every minute for 3 hours. Each frame was only 1920 x 1200 pixels in size.
2. This produced 137 separate video files. Some were unusable due to clouds.
3. Each file was processed using Autostakkert. Only 50 of the best frames were stacked and sharpened by Autostakkert. This produced 136 separate images.
4. Each image was processed in Astro Art.
a. the image was cropped to concentrate just on the filament.
b. From the first image, a reference point on the filament was determined.
d. For the remaining images, they were shifted accordingly so that the filaments would match.
Finally, all images were strung together into a single video file using RSpec.
