Description

More than 1 year and more 100 try to process this image.
I had to learn how to.
Thanks to @Adam Block for his explaination about GHS and his reducing star's process. Each time I do this, I ear "haloos...minus..luum". So much better than BlurX, and more natural.
This technique inspired me a other one :
With Hyperstar @ f1.9, you're gathering a lot of light and or you have deep sky details or you have big stars.
So now, after the first stretch, I separate my stars from DS starless picture.
Then, after enhancing contrast and all I have to do on starless, I no more do a single pixel math to ad stars because DS is added to stars halos.

So, here is the process :
- do a copy of the starless
- extract a luminance of stars only picture
- in Pixel Math, subtract stars luminance from starless clone
- starless_clone has the "holes" for the star only image.
- then, in pixel math, ad starless + stars

And you obtain natural stars over enhanced deep sky

Hope this will help you in processing. Have clear skies, all.
