Binning images increases SNR but reduces resolution. Drizzle increases resolution but decreases SNR. What happens if you use both?
The first thing you do with astrophotography image processing is to calibrate your images with flats, darks and dark flats. This process should remove dust donuts, vignetting and other issues you have might in the optical train.

The PixInsight Mure Denoise Script does a great job of removing noise from your astrophotography images. However, opting for Mure Denoise means that you are unable to use Drizzle Integration. I believe that a 2X drizzle integration creates a smoother final image.
But instead of doing what I believed to be right, I decided to run a test. I was going to compare what my image would look like with my Mure Denoise Script process vs the combination of TGV Denoise and Multiscale Linear Transform combination.
