Stacked several images to track the ISS across the frame and layered onto a single image of Saturn and Jupiter - all images shot in sequence at same position, zoom, and exposure.

As Saturn and Jupiter draw ever closer I was checking to see if the ISS might pass nearby and sure enough it did. Taken at 7:27PM, a series of 5 shots at 4 second exposure. At ~200mm (135mm lens on a crop sensor) the ISS fits barely inside the frame with Saturn and Jupiter.
