Weighted stacking

Firstly, what a fantastic program, it has revolutionised my pre processing!
A question about stacking, does Siril currently, or any plans to, stack using a noise weighted method? I know we can measure noise using the statistics, is there a plan to auto weight each frame in stacking to give a better result?

Hi, it’s not planned, maybe it’s a good idea, I’m not sure. If all images were taken with the same settings, as it should be the case when working on a single sequence, the noise will not vary significantly. Stacking several stacked images together however could benefit from this feature, like to combine several sessions.

Yes. For me the most important is to filter star shape.
As you say, noise does not vary a lot during a session except when light shut down or the moon is setting.
