Description

Quite difficult object. I found it very difficult to manage the bright Milky Way during image processing. I hoped to get out the red Ha regions stronger. Any hints for using better masks?

I'm not sure about the pink spot on the left side of the image. Is it real or caused by the camera?

Description: Hi, I worked on the Ha regions of the image:
I used the red channel and made a maske with range selection. From that I subtracted the range mask made from the blue channel to remove the stars. Then I used clone stamp to remove other areas than the Ha regions from that mask. This resulted in a mask that only contained the Ha regions. This allowed me to selectively increase saturation and brightness of the Ha regions.
Still ethical image processing?
