Lunar OSC gold-rimmed craters
Both panels of this image were from the same ZWO ASI178MC (OSC) capture.
I am trying to eliminate, or greatly reduce the gold highlights in the bottom panel of this image.
The top panel is the first raw frame of the of the video capture. The Bayer pattern is still intact, and the image is otherwise completely unprocessed. Zooming in on the upper limb, hints of the gold artifact are evident.
Every processing step seems to increase the gold color. It becomes more prevalent in the Autostakkert output TIF, and it becomes even more so after even moderate wavelet sharpening in Registax. A simple Auto Color treatment in Photoshop increases it even more.
The bottom panel is highly over-processed (debayered, stacked, wavelet sharpened, and saturation enhancement) to show more places that the gold highlights are hiding.
I can see these gold colored highlights around craters on the terminator in my first full disk lunar image off of this same camera a couple of days ago.

I cannot see them in a similarly processed image off of a Canon 60Da a couple of months ago.

I have also checked other's Mineral Moon images on Flickr, and I see some with similar artifacts and some without.
