Description

This picture was made with a Canon camera attached to a telescope. It is a result of two combined shots: one taken with a long enough exposure (30 sec., ISO 800) to get the Jupiter’s 4 largest moons (Io, on lower right, Callisto, closest to Jupiter, Europa, and Ganymede, the largest moon on the solar system, on the left) visible, and another one, with bright Jupiter taken for a short 1/500th of a sec and ISO 400. Then, the two pictures were combined to get a realistic view similar to what a human eye would see through a telescope.
