OK yes it looks difficult but not impossible [to get away with no tracking and pixel shift]...

Perhaps it'd be possible with:

ISO 3200 f2 8s
The total time will be a little over 24s. There will be minor star tracking, even at 16mm.

One question that keeps coming to my mind is, why use pixel shift for this application over regular stacking?

You would still use stacking. But the pixel shifted images used would be improved versions over non-PS images. Any improvement in your images will lead to a better stacking result.

Sounds good, though I am not sure about the nature of the improvement.

Well honestly that just wishfull thinking to me.

One issue of pixel shift is that standard software doesn't process it. The best raws converters we are used to don't really care tu support the feature... Neither do the most advenced noise removal softwares.

This mean that even if you could get a bit better on one side, you might get a bit worse on the other side. What will give you the better final result remain to be seen. Not clear it is on the pixel shift side except at low noise level.

And if something ever move on the scene, one longer exposure give your an undisturbing blur while pixel shift give your artifacts...

If the goal is better starlight pictures, maybe more specialized gear will offer better results than going for a camera with pixel shift.
