About evolution of prominences.
Those are 2 images which were shot at an interval of 30 minutes.
You will see the difference !
This makes me feel that with such fast cameras as Zwo or Basler we can limit the video at 5 seconds (with my Basler 1920 I can shoot 165 fps, so in a 5 seconds video there are 825 frames.It should be sufficient to make a good master frame!
As Autostakkert takes the best ones, they can be at the beginning or at the end of the video and so they can induce blurring ! No ? So the best is to take shortest videos as you can with your stuff...
I'd like the comments of the gurus who are in here :-)
