What programs are you using to process your stuff? Also I get the "orange" on the plasma but the surface of the sun I always end up with white not yellow like you get, how do you due that.
I use FireCapture for acquisition, I capture 8 bit .SER container.
I then align, sort & stack with Autostakkert!3 and output as TIF.
I then do tone curves and deconvolution and unsharp masking via IMPPG.
I do the rest in Photoshop CS5.1.
The reason the white areas of the plage are not coloring is due to being pure white, the data clipped. I capture with a histogram closer to 72% to ensure I do not clip bright areas. Also, when sharpening and pushing contrast, it's easy to clip the data into white again.
Here's my rapid tutorials on my work flow:
