PROCESS THE VIDEOS
Now we need to take the three videos and process them in software such as RegiStax. RegiStax can filter and stack the best frames from the prominence and disc videos as well as wavelet sharpen the still images that this process produces. It can also create and subtract the flat field frame. To create a flat field, open the flat field video and use the Flat/Dark/Reference > Create Flatfield menu. Save the image this creates and apply it (using Load Flatfield) to the two processed main images.
