The ISS was moving so fast that I had a lot of trouble manually tracking it. I did not see it on the monitor at all during recording and I
thought I had missed it.
Only when stepping through the video file later did I see it flash past a couple of times on just a few frames.
Jupiter, for comparison, was imaged at the same scale and settings.
Diameter = 41.8 arc seconds, brightness = -2.4 magnitude.
The moons were exposed a bit longer.
