Do all images need to have been captured with the same parameters for stacking?

No, but yes.

Let me explain.

There is no problem in stacking images captured with different parameters in Nebulb, but in terms of noise reduction these different images do not add, but subtract.

That is, if you stack many images and some of them have different parameters it will not affect, but if there are few images and with different parameters the noise reduction achieved by stacking may be much lower.

In case you want to use a specific image for the ground (with different lighting and capture parameters), you can always import it in Nebulb as “Master image” and then select it as the image for the ground.

What are your feelings
