OK blame Dennis. He got me back into this.
This small moving blob is Sycorax. Mag 20.7 (Guide 8), 80km of something going around Uranus in an apparently strange orbit.
You will need to look at the larger version.
Thanks Mike.
Captured through the 12" f5 ST7 with AO. 10min exp 20min between.
It was part of a series (5) to ensure the right object movement & position angle.

Congratulations – you’ve really nailed this one and at mag 20.7, yikes that is one dim body. The only challenge left for you now, in our solar system at least, is Charyon – LOL!
Top stuff and thanks for your help and contribution in chasing down these faint, somewhat esoteric little bodies, orbiting in the cold, dark and distant out reaches of our solar system.
You’ve obviously mastered the technique to do this work, showing that you can just “pop outside” and pull this amazing feat off so easily. I still need to work up to it, with a fair bit of planning and tweaking.
Thanks.
The 'things that disappear' are usually hot pixels or cosmic ray strikes.
3 or more images usually display these but I usually only use 2-3 images for the animation to save file size.
