Aside from the last one, I see enormous gradients introduced that I doubt are real, and that I don't see in Kathy's image.
Hmmm, I'm not really seeing gradients, there is extensive nebulosity which is changing from emission to more reflection across the image but I'd not call that "gradient". But it does make for a tough process.
Have you had a go at processing it, the more the merrier!!
Ouch I could have seen that one coming... now I may have to try, help this is mono imaging with multiple bands! I can only hope that the .TIFs are aligned... well I could use practice of course.
But, if you compare Kathy's image with the other ones you see a big difference in gradients don't you? Or is it my desktop settings that make it worse.
