Two space station passes in 5 minutes!
Hi all,
Tonight we had two space stations passing over Brisbane within 5 minutes! The ISS went over first, followed 5 minutes later by China's Tiangong 1 station only a few degrees away from where the ISS had been. I'm guessing it is a fairly rare occurence to have both in the same patch of sky only a few minutes apart - although it happens again tomorrow night if you're near Brisbane.
The ISS was magnitude -1.3, and Tiangong 1 was mag 2.4. For this image I used Startrails to stack a series of 4 second exposures taken with a Canon 50D at 800 iso and EF35mm f/2 lens at f/2.5
Cheers,
Stephen
