Jupiter with it 4 brightest moons which are called Galilean moons. From left to right they are Europa, Io, Ganymede and Callisto. The picture was taken with a Vixen 80L (80/1200 mm Fraunhofer achromatic refracting telescope) at February 25th 2014 at 7:04:27 pm German time. The names are added to the moons. There exist a German improved version with brightened up moons there. I can do the same changes for the English version on demand.
