Thanks team!
It was a marginal event. Clarity was poor and the seeing had dreadful spells. However, the main event was clear at 8 frame integration.
I've marked where the rings 'may' have been - one certainly wouldn't have discovered them with this observation! More interesting is the dip later on which is in a period of perfect seeing and very obvious visually.
Sadly I think I'm the only one to observe it unless some pro's are out here, so we may not have got to help with the size
