The Moon - 2022-08-19 08:13 UTC - Crater Copernicus (Reprocessed in PixInsight)

This image is about comparing Photoshop processing (my customary tool) of lunar data to PixInsight processing. This image, processed in PixInsight, is rendered from the same data as the Crater Copernicus image processed in Photoshop and posted on 2022-08-22.

 

My impression of this image is that although it reveals more detail than the one originally posted, there seems to be some remaining softness that can be improved by better seeing and use of a UV-IR cutt filter

 

After registration and stacking in Autostakkert, all follow on processing to this image was in PixInsight instead of Photoshop.

 

PixInsight processes used:

ChannelExtraction to pull out separate RGB channel images

LinearFit to normalize channel levels

ColorCombination to reassemble into a single RGB image

UnsharpMask for sharpening

CurvesTransformation for RGB, saturation and CIE c* component stretches

Done
