Image Description and Details :

Transit from Ganymede 25 July 2021
Average night conditions due to fine mist. The idea was to make a Gif of the Ganymede transit with at least 1 hour of duration, but due to fog the light conditions varied a lot, which would prevent having a homogeneous Gif.
Good thing Ganymede himself came out with good definition, note that especially in the image with the infrared filter the dark region of Edfu Facula at 2 am and the light region of Osiris at 6 am are perfectly distinguishable in the photo, which shows that they are not artifacts.
PS: The high resolution image of Ganymede was taken from the Virtual Planet Atlas.
