There is no guarantee that you can achieve a good result with the script on drizzled images.

But try tweaking variance scale. Maybe try a binary search? If 1.0 is bad try 0.5. If 0.5 is bad try 0.25, otherwise try 0.75, and so on, halving the search range at each step.

Thanks, will give it a shot.  This is just part of my routine workflow now and I have added the drizzle into that workflow, so there is a slight train wreck in PI negotiating these two procedures....

Hello there,
I have an image that suffer dithering noise!
Look at this example:!iZZESToS!vfLCSok_yMuJu_T6MhON-MTWMeU74yqg4jMrSjBYGKU

I am not familiar with PixInsight but I always process my images using BatchPreprocessing & ImageIntegration scripts.

I read that I can use DrizleIntegration script directly inside BatchPreprocessing & ImageIntegration, but I am confused because I cannot understand if I need to combine all the c_d_r images + drizzle data or drizzle data only.

The guide in the 1 th page shows as last step the DrizleIntegration script, but the step before shows the ImageIntegration scripts...
If I run the ImageIntegration scripts I have the final image, so how can I set the parameters & combine the drizzle data ?
Anyone can explain me better?

Is this script really able to remove the dithering noise from the image, or is it better to shot again with more luck?!
Thanks, Filippo
