I had consistently excellent seeing to image the emergence of Ganymede from Jupiter's shadow prior to its occultation by the planet. Overall I was able to image this process over 2 hours, capturing approximately 40 RGB runs of 1 minute per colour channel.
I intend to make this interesting event into an animation which is quite a bit of work.
Once again I had superb detail on Ganymede for each colour channel. Practically every single image whilst the moon crossed from Jupiter's shadow until its occultation was perfect. I was therefore able to align and stack 23 images for each colour channel giving what I think is excellent resolution. The appearance is quite consistent with the capture I made a week earlier.
