Hi all
On Sunday morning, we had beautiful clear skies and I was able to capture an image of Jupiter with Io’s shadow in transit, followed by Io itself shortly after.
Unfortunately the conditions weren’t great and the image is really affected by the poor seeing, even though Jupiter is now climbing to a respectable 40-45° in altitude before dawn.
I captured 9 RGB runs but chose the two sharpest images for display here. They were taken approximately 30 minutes apart. Io can be seen just inside the limb in the second image.

Thanks for looking.
