I tracked the Tiangong pass with my Canon 15x50 IS and took some 10-second-long iPhone Night mode photos. Here's the best one. I had to darken the background sky quite a bit to bring out the stars.
The first-magnitude star Vega and the constellation of Lyra lie to the upper right of the Tiangong. The double star Albireo is directly above the Chinese space station.
The Tiangong was quite ruddy in hue at the start of the pass.
