What Galileo Saw

At the limits of what a longish zoom on an APS-C camera can capture. I probably should have set up the camera on the gimbal mount instead of a ballhead to make locating the object easier. This is Jupiter, with the four Galilean moons. Roughly what Galileo saw when he trained his telescope on the largest planet in our solar system.

The moons from left to right are Callisto, Europa, Io and Ganymede

Callisto is barely visible in this picture. It’s the second largest moon in the Jovian system but it has very low reflectivity (albedo), which makes it rather difficult to see with binoculars.
