This image is an example of what you may see when observing Jupiter through a telescope. Surface features are visible, including the Great Red Spot, as well as Ganymede to the top right of the image.
The image was taken by astronomers at ESA on 29 September 2010 as part of CESAR education at ESAC. It was captured using a Celestron 8" SCT telescope, a Philips ToUcam Pro camera, a near-infrared cutoff filter and a 2x Barlow lens. With this set up, a video of 15 seconds was captured and then processed with RegiStax to stack all the individual frames. This image is the result of this processing.
