Update.
I made the mistake of not blowing up each sub and looking really critically at it...a standard thing but one of those things that is easy to overlook...they looked ok but some, most had trails of a millimetre sometimes more...how I ended up with rounded stars after processing is unbelievable...and although the stars got fixed the other stuff must have had detail badly corrupted....anyways that what I have been doing since my last post and maybe 75% went in the bin.
Lesson..don't expect decent results when the mount is not up to carrying the scope...and most important...check your images as they come in regularly to see if focus and tracking are holding up and most of all look at every image blown up and make sure it is as close to perfect as possible...this batch I still let a few by that really were not acceptable but in the case of my S11 I near ran out of images..I just need heaps more data let me five hours more..now all I have is about an hour and a half ...anyways I will process what I have and see if I can get better even though most of my subs have been dropped in the bin.
So I continue to learn by mistake ..the biggest mistake was not remembering what I have learnt and waste all this time being reminded.
This is so much like archery ..you have a check list and failure to address one single point results in failure.
Hope others may benefit from this.

edit addition.
I reprocessed with only 15 at 90 second for S11 AND 20 for O11 BUT everything with not trails or poor frames..well somewhat poor but the best and the result seems better even though very limited data..the reprocess is in post number one.
