Nice detail in the emission zones but the photo has an interesting mottled texture to it overall. Do you know what causes that?

It is short on colour time so it is mainly Ha. The Ha darker areas tend to be mottled so you are probably seeing that. It doesn't show on my monitor but that's another barrier to image processing - the monitor's performance.

I'll shoot some more colour once I capture this amazing comet that is around at the moment.
