These are excellent Christian! What sharpening routine do you use? Unsharp mask or Lucy Richardson deconvolution?

Thanks Mark and Terry !
Mark, my processing flow is very simple. It is the same for Ca K, Ha or white light HR images. I use AstroArt, but it can be done with any other software
- unsharp masking : sigma = 1.4 pixels and coefficent 8,
- very small amount of RL deconvolution : sigma = 1.1 pixels (gaussien), 2 iterations,
- adjustments of min/max levels as need in Photoshop,
- no gamma change (except on prominence Ha images).
For FD images, I only use unsharp masking since contrast is very strong due to sampling:
- unsharp masking : sigma = 1.4 pixels and coefficent 6.
Hope this helps.
