Observing Summary:

A good night with steady skies.  We spent a fair amount of time trying to focus
the telescope, and while we had no trouble getting pretty decent focus, we were
not able to get the tight radial profiles that we achieved two years ago with the
same instrument.  Guiding went well all night, so that wasn't it.  We also had an
episode of pilot error trying to perform an offset with the xtcs gui.  The tcs ended
up confused about the telescope's position and pointing was lost, but we fixed
both. Took a little time out of our night.
