I took this photo using the NexStar 8SE telescope along with the NexImage 5. The software used was iCap and I configured it to use 4x binning. Using 4x binning gives a larger capture view when recording the video. The photo shows all 4 Galilean Moons. The moons starting out from Jupiter are Europa, Ganymede, Callisto and IO. Galileo Galilei discovered the moons in 1610 and were the first objects found to orbit a body that was neither Earth nor the Sun.
