Observing Summary:

We're happy to report that everything went smoothly.  The telescope worked
well -- no problems at all.  Target acquisition went smoothly (even with the slit
viewer monitor in the dome) and guiding was completely steady.  It does seem
that when tracking (but not guiding) objects drift west more rapidly than we
recall.  But, again, there were no issues at all with guiding.  The focus temp
compensation appears to have worked really well -- no noticeable focus changes
during the night.  Seeing was pretty good, and no evidence of clouds all night.
No sign of cirrus here in morning twilight, so it was probably photometric.  We
got some great data.
