After midnight it cleared, and this allowed me to capture the Keyhole satellite USA 161 (01-044A) again. It was nicely on time. A bright mag. 0 stray, which turned out to be the Russian r/b 84-072B, made a similar trajectory 3 minutes earlier.
Below image shows the Keyhole (01-044A) crossing the Milky Way in central Cygnus (I pushed the levels and contrasts of this image a bit in Photoshop to bring out the Milky Way better).
