Thanks so much to you all for the encouragement and kind remarks.

I note that some are struggling to see all of the events within the animation.

These are not events with big signs on them saying look here I am. Over the past twelve months I have become accustomed to eeking out minute storm detail on Saturn, so have had quite a bit of practice at this. Of course it would be great to have a higher res CCD but I get the most I can out of the equipment available to me.

This is such a rare event that I really want you all to see this stuff.

I also have problems picking up Dione, unless my laptop screen is bang on the right angle for me. Then Dione becomes a small crisp white dot, immediately under the rings on the right or western side of the planet, mid way between the Cassini Division and the outer edge of the rings. It also helps to not be too close to the screen.

Note, the first thin dark band that appears below the ring plane on the planet. This is the SEBn (Southern Equatorial Band north).

Follow the movement of Dione as it approaches the planet, as it crosses the edge of the planet it becomes a small dark diffuse disk that moves through the SEBn. It travels about a third of the way across the planet before the animation resets.

Mimas is very difficult to detect, but keep at it because when you do pick it up it becomes quite obvious. Mimas is a very small, slightly brighter than the background dot. It appears to be virtually in contact with the underside of the ring plane. It is initially above Titan and moves rapidly across the disk of the planet, almost rippling the the underside of the rings as it goes, at about twice the speed of Titan.

I really hope these instructions help.

Regards
Trevor
