Observing Summary:

Ended up having a good night observing despite issues with the 
guider. The guider got stuck early in the night and would not 
move at all along the y-axis. It was also very far off position
wise in the x-axis. Eric attempted to fix the guider remotely 
but was unsuccessful. I lost about an hour and half of 
observing time trying to fix the guider with Eric. 
Using some guess and check work I was able to find guide 
stars that were along wherever the guider 
was stuck and was able to successfully guide for the 
remainder of the night. Guiding was not as good as previous
nights but given the circumstances I was still able to observe.

Seeing was not as good as the past two nights. Shortly 
after midnight clouds formed on the horizon. By dawn the clouds
were spread out in the East. Moderate wind for most of the 
night.
