Hi Philip, I too are rather new having started solar Ha imaging March 2016. Highly recommend Autostakkert (free) which will place tiff images into your avi folder. When these images are opened in Registax 6, it will open at the wavelet section. do not over sharpen. Use Registax 6 for your prominence images; they place points along the edge of the disk automatically. In my experience, I find adding more points often bring up artefacts! Re PS; Paste the surface over the prominence image, select difference mode, click on move tool and use arrows to adjust. Go back to normal. Add a mask to the surface (top image blue), "ctrl I" to make it black. The prom image now on screen.
Use brush tool circle to move over prom, and up comes the surface. Crop, merge down and save. Not certain whether this is 100% correct method, but seems to work reasonably well. Kind regards, Arthur
