I already had 40x(15s,30s,60s &120s) from the 15-05-2010 when CorAus was lower in the sky.
By watching the IR satellite movie on the BOM page you can estimate if there is a chance of even a few hours clear of cloud. A desperate man will resort to any means to collect some data when the Moon is absent.
On 8th and 9th ie Sunday and Monday just gone had some hours of clear sky and managed to get the rest of the data. There was a bit of cloud dodging as this tends to screw up autoguiding. I have a video feed of the finder scope to my computer screen inside so I know instantly if cloud has turned up from a nice warm room. Here is an animated gif showing what I can see in real time in the finder screen. The GstarEX is producing a new frame every 2.6 seconds. 550k

The finder zoom can be set so the field is almost exactly what the 5DH captures.
Below is the CorAus field and the Helix Nebula field. The finder is that sensitive that I can see the Helix Neb in real time. I have added a jpg straight out of the camera adjusted for levels.
