Jupiter - 2022-08-30 0717 - Reprocessed in PixInsight

This image is about comparing Photoshop processing (my customary tool) of planetary data to PixInsight processing. This image, processed in PixInsight, is rendered from the same data as the Jupiter image processed in Photoshop and posted on 2022-09-02.

 

My impression of this image is that it is interesting, but not as sharp as the Photoshop-processed image. I will experiment with the order of processing to see if a better result can be optained.

 

After registration and stacking in Autostakkert and de-rotation in WINJUPOS, all follow on processing to this image was in PixInsight instead of Photoshop. In particular, Before any sharpening, I separately de-rotated all images for each color channel, and did a de-rotation of R/G/B Frames.

 

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
