The image of the disk is composed of a stack of the top 10% of frames from approximately 30 seconds of video.
The prominences were also stacked from a video with longer exposure times on individual frames. Video frames were cropped and aligned in PIPP, and stacked using the Autostakkert2! software.
Final processing (combination of prominence data and disk data; sharpening; level adjustments) and coloring was done in Adobe Photoshop.
