I had a problem with my flats and have a few dust spots.  Is there a way to use a tool in APP to remove those spots?  Please see image.

Hi Michael, @msamazing

An issue like that is not yet possible to correct easily in Astro Pixel Processor. You can try to use the Remove Light Pollution Tool, to correct that problem parts step by step though, but it will be difficult I think.

Best solution for problems like this would be to fix your flats/flat-field calibration so the dust is really gone from the start. Or make much larger dither steps, like 50-100 pixels, that can do wonders as well for moving dust or big dust particles on the sensor.
