Ganymede was very difficult to process : the dark circle inside, seems partially to be an aftefact. However, some of this circle is actually true also with the white spot when checked with Winjupos simulation. Even with a very small touch of processing, this dark circle is there... First time that I face a moon of Jupiter which is such difficult to process.
