Observing Summary:

The issues that slowed down data acquisition were just learning 
the instrument.  Even with a bit of a slow start, we managed to 
get some data on a target before our fields were up and some 
data on both of our fields using the masks!

The M44 mask (in slit position2) had a slight misalignment 
between stars at the top of the field and at the bottom.  
Could we have its placement in the wheel checked to make sure 
it isn't slightly bent?

We closed at about 3 a.m. when KPNO issued a dome closed due to 
threatening clouds warning.  The warning did not clear, so we did 
not reopen.

We also want to note that the engine that moves the slit really 
struggles when the slit is nearly completely open.  It shakes 
quite violently at the top of the dome, so we wanted to point 
that out, in case it's new or has gotten worse.
