I was able to include Saturn in my session this morning,under reasonable conditions.
Two moons (Dione and Tethys) were noticeable as I processed the R and IR images,
and I have slightly increased their brightness to highlight them.
The polar hexagon and vortex are well seen,and the vortex appears quite large.
I have included a more aesthetic version of the RGB,just because I like it so much!
The national lock down here starts at midnight(4hrs from now),
but thankfully this should not impact my imaging in any way.

Imaged Saturn March 26th in variable seeing,the best of it being the 685nm IR. The RGB data was less than great. While working on the IR data an old friend popped out. I believe it is the 2010 GWS AV which I have tracked since it first formed. It is a dark spot embedded in a brighter envelope which was unique to this feature through 2019. Using my ephemeris from last year,so the same reference L3 and date but with the output set for March 1st to 31st 2020 with a drift rate of ¬1.5450 degrees / day,the AV would have had a CM transit Mar 26th at 19:19 with itfs L3 171 degrees and an alt for my location of 47 degrees. All of that seems to fit this observation. I measure the AV to be at approx Lat +43.2 L3 168.6
There are also two ripples on the edge of the EZ the most prominent one preceded by another with lesser amplitude. All data has been uploaded to PVOL with a link here to my animation of the 685nm IR data which covers 32 minutes of Saturn rotation.
