The ISS hit a peak of 80 degrees last night, almost directly overhead, and I captured a very clear shot. Then I took some good pictures of Saturn, also brightly visible last night, and made a composite of the ringed planet and the ISS for the second photo posted here.
The ISS travels at 18K mph(29K kph)/250 mi.(400 km) up, and Saturn is over 800M miles (1.3B km) away. My equipment was the handheld Nikon P-950, max optical zoom 2000mm for ISS, plus additional 2x digital zoom for Saturn. Shutter 1/1000 s.
Please enjoy these two photos!
