Thank you for uploading! (I moved this into its own topic)
First off, your dataset appears color balanced. Please turn off color balancing in your stacker (for recommended settings for popular stackers,
see here).
Stacking artifacts are indeed visible; zoom into the image and look at the edges. You will find a 1 pixel "border". After running an inital Wipe another 1 pixel column at the left edge can be seen as well. You really need to crop more than that as there are still other artifacts visible along the edges;

That said, the new Wipe can model and correct such artifacts a lot better now. And giving it a mask that contains the areas it may sample yields an even cleaner result;

When you "Keep" that result and launch AutoDev, all you need to do is specify an RoI over a slice of the galaxy to give it an idea of the sort of detail it should optimize the stretch for (
see here on what AutoDev does and how it works);

From there you can enhance local detail, etc.
For coloring, when you hit the Color module (preferably one of the last steps), we can see that the default settings StarTools comes up with are too green (use MaxRGB mode);

Once we are absolutely sure the color balance is now correct, we can use the Cap Green function to kill any spurious green dominant pixels.
There is some slight chromatic aberration (or channel misalignment?) visible (also the cause why StarTools suggested a default color balance that was too green). The Highlight repair setting helps correct aberrant coloring in the highlights.
See here on how to use the Color module and how to color balance correctly.
You'll end up with something like this for example;

A good yellow-ish core (older stars) and bluer outer rim (younger stars) and red/brown dust lanes. Perfect!
Hope this helps!
