Thanks Greg and Frank (and all those who voted). The other entrants this month were all absolutely stunning . Certainly they are all easier on the eye and required much greater investment of time to achieve than my fuzzy snapshot. I was very lucky that everything fell into place - an almost perfect pass (maxing out at 82 degrees above the horizon), less than an hour after separation, clear skies and the fact that I was able to get home with enough time to set everything up without needing to rush too much (you never can tell if passengers will arrive on time or make you wait). Then there was the camera settings. On previous attempts at the ISS I used Jupiter as a focus and exposure aid. This time I had to make do with a star of similar magnitude. So, a lot of luck was involved. I think it will be quite a long time before I manage to get another shot like that, but I will keep trying. It would be interesting to see what results could be achieved with a DMK camera running at 30 frames per second or more.
