The seeing was particularly good on the 18th November 2011 for this image of Jupiter with three of its Galilean satellites. Ganymede is at upper left, Europa below and Io on the right. The fourth, Callisto, was far out of the frame on the left.
The image was made using an Imaging Source DMK mono camera with a colour filter wheel on the Meade LX200R 14" telescope. For each filter (red, green and blue) a sequence of approximately 30 seconds of video was taken at 15 frames per second . The video sequences were processed in Registax, Maxim DL and Photoshop. Notice that Europa moved a small amount between the Red and the Blue-filtered images. The Great Red Spot can be seen in the south equatorial belt [Jefferis]
