Looks like you loaded a 8 bit image?

It's only luminance. No sky to do the colors yet.

The reason I ask is you can see the steps in the image from the center of the galaxy outward. They should not be there unless you made the image 8 bit. A lot of info is missing. You can go from DSS to Photoshop and stay at 16 bit when you save your stack.  Not sure where you lost the resolution.

I processed witth 16 bits. I only converted to 8 bits to publish as JPG. What you might be seeing, is the strong stretching to show the thin informations of the arms.

images of this galaxy on the internet usually only show the center of the galaxy and saturated.

It is a small and faint object, wuth magnitude 12. To obtain a better quality, I need a better sky.
