FINAL PROCESSING AND SHARPENING
We now have an image, made of two layers, that shows both prominence and disc detail. At this point it’s worth checking that the solar limbs in both the prominence and disc layers are correctly aligned with each other. Now the two images are together, you may also find that you want to fine-tune their colours and crop out any unwanted edges. Once you’re happy with the image, merge the layers. Lastly, a gentle unsharp mask can make fine details pop out.
