Observing Summary:

Worked for all night. 
Conditions were non-photometric for the most of night.
Some clouds in the beginning of the night made several images useless.
Afterwards, the sky was clear.
Some images were lost due to a slight problem with the guider - 
it made the telescope move quickly in N-S direction by a couple of pixels 
and thus making all stars double. This was solved by adjusting 
guider parameters to more conservative values and the guider worked well 
for the second part of the night.
