I’ve been playing around with different techniques before beginning a process on my elephant trunk nebula....using starnet on each individual channel and seeing if there is a difference when using starnet on a combined image. All good curiosity.
I’ve noticed whatever method I use that I get purple rings like dust motes in some parts of the image with a slightly mottled looking background where this occurs. Examining the raw stacks, expected to see a flats issue but can see any sign of motes if under an extreme stretch..everything looks normal. Anybody else experienced this and know what the cause and solution (apart from clone stamping) is?
