pretty good result Steve.
best guess is that the effect is due to seeing jitter - this is often caused by the jetstream. You could try:
- Stack a lot fewer frames to see if that helps by getting rid of frames with bad jitter artefacts.
- Set the minimum brightness threshold (min bright) to zero to ensure that the faint ring edges do not get lost on poorer quality frames.
- Try larger align point boxes and fewer align points
- use a bit less sharpening in R6
for interest, how many stack points did you use?
otherwise, you will need to find a night with reduced jetstream or you could maybe try a higher framerate next time you are imaging, to try to freeze the worst of the seeing - what framerate did you use for these?
