The filters used for this image cover a broader range of the spectrum than human eyes can see. Galileo was 687,000 kilometers from Callisto when it took this image, at a phase angle of just 1 degree. Image scale is 6.9 kilometers per pixel. The image was reconstructed from the original data by Ted Stryk. About 10% of the right side of the disk was marred by data dropouts; Stryk reconstructed missing data from images taken through other filters.
