Apart from the colour coding this is what you would see through binoculars. It is possible to photograph the 4 satellites with a simple camera on a tripod.

Jupiter has many other satellites but they are all very much fainter than the 4 Galilean ones.

Hourly animation of the display above can be done by selecting the arrow for incrementing hours in the calendar and then pressing the Enter key or even holding it down so it repeats.

The calculation scheme is from Jean Meeus: "Astronomical Algorithms", 2nd edition (corrected August 2009), Willmann-Bell Inc. The lower accuracy scheme of the two given in chapter 44 is used. This is accurate enough to show the layout on a given date but not accurate enough to show whether the satellites occult or eclipse each other.
