Thanks Netwolf and Alex.
I was fiddling around in Gimp with the sharpening and the sizing of these three shots so they all wont be the same, even though they came from the same AVI.
I checked Astronomy 2008 and the GRS time was 23:19 for Sydney last night, and the avi was captured at 23:50 so this seems like its correct.
Woohoo, my first GRS.
