I thought it would be interesting to show the progression of processed images in this sun spot. the original video capture was 1,200 frames. The stack in the lower right was the best 15 frames. The final greyscale image after processing is in the lower left, then the colorized image and finally the inverted greyscale and colorized image.

Special thanks to Gabriel Corban for his excellent processing guidence.
