Marty, was this drizzled? The reason I ask is that at full size there are stacking/processing artifacts around some of the brighter features (crosshatch pattern). I normally only see that on lunar images that have been drizzled.
No drizzle, I noticed the weird artifact around a few specific features too. I usually lower deconvolution and then increase unsharp mask in IMPPG, and noticed this. I captured with a QHY IMX183 OSC sensor in FireCapture and had to do a two part mosaic, I aligned and stacked in AS!3 with no drizzle or anything other than debayer and RGB channel align. This went into IMPPG for the luminance processed (low deconvolution, high unsharp mask). The non-IMPPG result went into Registax 6 and had the RGB align done there and nothing else. Took the color image into CS5.1 and did another channel alignment then pushed saturation (I do a small saturation layer and simply duplicate it 10~13 times) then do a final saturation layer with higher vibrance and a contrast layer to finish the color. No other routines used. I then put the IMPPG B&W image over this color image as a luminance layer. Not sure where the pattern artifact introduced, oddly at the craters in some places. I saw this too after doing it but wasn't sure which step introduced it to the data. It's only noticeable when pixel peeping of course, so I just left it alone. Plus no one really cares about moon shots lol.
