Weather forecast was very good but a bunch of high thin clouds moved in just after astronomical dusk. Pain in the behind. Seeing gradually declined during the night rendering my Saturn and Mars imaging pointless. I did manage to get a decent Jupiter image.
This is 5 20% stacks derotated in WinJupos. I took the advice of many on the forum and worked with 60 - 80% histograms last night instead of the 25 - 40% attempts I had been making earlier. This did seem to produce better results. Also found that as suggested focusing using a low gamma value on FC was helpful as well.
