But basically postprocessing and image staking allows you to use high iso with minimal quality loss

If you're only taking a single exposure then yes lower is better (when shooting a static scene from a tripod)
But I have taken multiple exposures and combined them in post so the noise averages out.
Also the stars move so there's only so much light I can capture and I would need to boost the exposure in post that would also then increase the noise.
As for the foreground, I was cold and didn't want to wait 8min extra so I used a bit more ISO.
The real world difference between low and higher ISO isn't as bad as it seems in the datasheet, especially when you throw postprocessing in the mix
Thank you very much
