In my Astronomy Lab we took 120 seconds of video through our telescopes using simple webcams. Then we used RegiStax V4.0 (a free image processing software) to stack our 120 seconds of video. Here is our finished Jupiter & Moon photos. (Note: The second image of Jupiter was created from the video that our professor took, but we stacked the frames.) You can even make out one of Jupiter’s moons in the second photo! :)
