Briefly, I normally use “Sharpcap”, take 2 avis of 200 frames each, 1 exposed for the disc, 1 exposed for prominences. I then stack them with Registax 6, import them into GIMP, “colorise” the disc yellow and the prominences red. I then use “Layers” in GIMP to combine them to produce the final image. It is very quick once you get the hang of it.
