Some clear skies and a collimated 12" SkyWatcher Dobsonian with a Canon EOS 600D chasing the ISS tonight. The second pic is a compilation of every frame of the video the ISS appeared in out of the 4000 or so recorded. Description in the thread below. I modified the ISO and shutter speed on the fly and I think I ended up with 1/2000 sec at ISO 100 at 30fps.
And now...... a video:
