Good idea. Is there any benefit shooting in RAW mode? Is it best to apply noise reduction on each photo before stacking or just stack the photos without noise correction then apply any noise reduction if required post stacking?

I think so but not sure how good software can handle the ISO25600 raw from GX7 such a relatively old camera.

I also concern that if the raw development software over does NR that might smear fine detail, such that might not produce a result as good as stacking from OOC jpg.

It has demonstrated in my second batch of testing according to member's suggestion using images from NR-5, NR0 and NR+5. It seems that despite NR-5 got noisiest OOC jpg to work with, the stacking result is as good as those NR0. Both (NR-5 and NR0 have similar detail). The stacked result from images of NR+5 (noise been erased, but also less detail) showed similar noise condition as the other 2, but have some detail lost.

Thank you for your head up.
