Description

I made 10 RGB runs of 1 minute per colour channel. I then selected and integrated 7 such that the midpoint was the exact time of Io's occultation by Jupiter's shadow. Io was processed separately and inserted at the correct position where the moon entered Jupiter's shadow. A mask sized to match the planet, was used to hide the portion of the moon that had moved into shadow. I calculated that the umbra of Jupiter will be of the order of 99% of the planet's diameter at the distance Io is orbiting behind the planet. The individual capture at that midpoint timestamp of the capture was used in a layer to position the moon.
The planet has a particularly beautiful aspect at the moment. There seems to be a red flow into the complex wake. Equally there is a very interesting bleed out of red material I presume out of the GRS and flowing into the GRS Hollow towards the eastern limb.
