This is a capture I took of a very rare event on 15th Aug 17:15 UTC, with Jupiter's moon, Ganymede (L greyish dot in the middle of Jupiter), casting its shadow on (eclipsing) Europa (middle semi-black spot) with both their shadows cast on the planet (R combined black dots) with Callisto far right of the picture. Unfortunately, the weather was not on my side so seeing was terrible, leaving me little detailed data to work with.
This is a capture of one RGB set using Firecapture. I stacked using AutoStakkart3!, sharpened in Registax, and applied final touches with PS and Topaz
