Description

Here I have made a different processing approach to my recent Ha and RGB data of this target. I made a star-less version of the previous HaRGB image and then used the pure Ha image as lum. I then added the stars from the HaRGB image (using a star mask from the Ha data to grab them). I guess it is a kind of tone mapping approach. I feel it brings out the details in the nebula better and makes the stars smaller and sharper.
