I have tried to use the cloning tool but this ends up looking even worse than the original faint reflection when using K-S.

Below is is a crop from a single position final image. The reflection is just below the glob.

You can see from the partial mosaic where two positions were used this reflection is totally gone.

Does this help?

Thanks Bert. It does make a lot of sense. Offset + data rejection. Drawing on this line of thought would creating a difference layer in photoshop then using it as a mask work? I'm thinking I have loads of TIFF/PSD files already with halos that I haven't necessarily kept all the original raw files for.
