It was a mostly cloudy night which was used to obtain calibrations for different configurations.
Toward the end of the night the sky gave us a break and we were able to make a focus sequence and to observe the ToO object.
The focus sequence (eg image eng.29569) does NOT show a gap between the last two exposures of the sequence, although it is clear that image #9 is a ghost. There are 10 images in each sequence and there were supposed to be 9.
