Tom, I have seen this feature on Ganymede visually in my 16". I am curious if
this was visible thru the 10". Lynn

Subject: [AZ-Observing] Jupiter & Ganymede In Good Seeing
We are having another long run of pretty good seeing in the city tonight. I
used the usual setup to image Jupiter, and then panned over to Ganymede, and
took a separate image. Ganymede's disc is currently 1.8 arcseconds across, so
details are fleeting. The image has a 4x resample on Ganymede in order to make
it easier to see the detail without hunching over your display.

The feature that is visible in the image is Galileo Regio.

software shows the feature in a longitude that matches the image.
