There's a very clear improvement, but I have a question:

Is there any advantage of doing the stacking, over using a lower ISO with longer exposure? In my mind they both ultimately seem to do the same thing (gather more light over time) and have similar requirements (needing to keep the camera and scene still).

I can imagine the ability to align frames when doing a stack could provide a sharper result in case of small camera movement? Or are there other advantages?

It allows me to shoot handheld in relatively dark environment.

Although stabilization (limited to either 3~3.5 stops on lens OIS or max 1 stop on IBIS of GX7, better on GX85) helps to use slower shutter speed, there is a limit on the slowest shutter speed for a steady image and when it is dark, higher ISO is still required.

The beauty of stacking can get clean image, which might come out even better than OOC at base ISO. It also permits using relatively faster shutter speed making handheld shooting much easier in the dark.

Yes, steady shots could result sharper stacking result. Tripod is the best but it is against my original intention on using stacking.

It's a useful technique. Some Olympus cameras offer a "Handheld Starlight" mode which takes 8 shots and then stacks them in camera for a similar effect.

Yes, there is also similar modes, e.g., iHandheld Night Landescape(?), for Pany but not available to GX7. These are also pre set scenery modes that the camera will decide when to use, or the shooter has small control .

The discussed operation can have more control by the shooter, and can be used anytime. I can also take any number of shots that I think fit. Indeed although I set ISO25600 to the C mode, I can change to use any ISO depending on the situation.

The disadvantage: can only see result after PP instead of immediately from the camera.

As said, just attempted to see how C mode can be used and upon it, to see any other application could be suggested by the community. Sort of brain storming exercise?

Thank you for your comment.
