Can the masks be modified after the stacking is finished?
Yes, Nebulb also allows you to modify any of the masks once the stacking has been done, for this purpose:
1. Modify the mask as desired.
2. Once you have made the necessary modifications press the refresh masks button (so that Nebulb uses the new masks you have defined):
3. You can repeat this process as many times as you need to get the result you want.

More light pollution → More images for stacking. That said, I have found ...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 for noise reduction these different images do not add, but subtract.

In principle you don't have to flip any image (and even less if you stack in RAW). Nebulb always performs stacking with all images oriented in the same way. This is something that Nebulb manages internally based on the information of the images and ...
