Compare this to the image below it. For some reason the individual combined 5 sec exposures have NOT burnt of the central region too much. But the individual 2 second images, for the image taken on the 26/11/2010, has? Not sure why. Poor skies on the 4/12/2010 compared to the 26/11/2010? It is not a strech issue as the counts are saturated for a larger area.
