Hello again,
Better image scale and colour balance with this reprocessing attempt. Used drizzle stack option in AS!2 prior to processing in WinJUPOS. Total of 24 minutes capture time, 4000 best frames.
Attaching a link to animation of six composite frames showing rotation of a storm cell in the NEB. There may be others too but not as well visible amongst the noise.

Thanks for having a peek,
