Processed in APP - this time it was processed form start to finish in APP only, the latest version  1.083.

Once it gets a median filter or something to give a little bit of noise taming, it will be great. Although the noise in this case was calm, and avoided stretching the background dust too much as I did in a previous iteration. I can do this offline of course, but I wanted to see what an APP only process was like (HSL selective color (blue) was a percent or two high, tiny artefacts that I'm too lazy now to undo).

Clear skies all, raining sideways for me!
