Very nice Mark, you've got the GRS bang in the middle with junior not far behind.
Nice lot of detail.

The seeing was reasonable but not brilliant.

The Skippy Sky seeing forecast indicated there would be reasonable seeing aound the time of red spot transit and then it would deteriorate.  This is precisely what happened. 
Meteoblue indicated excellent seeing all night - this was very over-optimistic. 
7Timer indicated really bad seeing all night - over-pessistic.

Very nice indeed Mark Is Skippy Sky an aussie forecaster?

Looks very good Mark, loads of detail. It didn't look clear enough here to have a go.

Any idea about the halo effect around the planet? Looks to me like not enough alignment points near the edge.

That's the one.  But it gives forecasts for Europe as well. 
Go to http://www.skippysky.com.au/Europe/
then click on England then click on seeing then click on the forecast time.

That might well be the case.  I just did a quick process on some data that looked reasonable.  I've also got another couple of hours of data to trawl through - I would have had more but a cloud came across and blew up the guiding.  But in any case, the seeing degenerated quite a lot later so I think the best data was (luckily!!) around the time of the GRS transit.  

So I'm still waiting an opportunity to do a complete 10 hour animation
