Without their clever programs this image would never have been possible.

It is made from 50 Gb of video (95,000 frames) obtained over an interval of 45 minutes. During those long runs there was obviously
considerable rotation of Jupiter. WinJuPos allowed me to derotate the runs, resulting in a very low noise image which could then be
processed very aggressively.

The seeing that night was also a help.
