Worked for 11 hours (all night)
Conditions were Photometric most of the night.
No equipment or software problems were encountered.

   Beg: Seeing 1.1 arcsec, Clear, Winds Calm
   Mid: Seeing 1.0 arcsec, Clear, Winds Light & Variable

Observing Summary:

Very nice night with some great seeing around midnight.  Temperature
stayed up and wind was calm until the early morning.  Found
one new high-z radio-loud quasar.

The tracking only failed once, around 2am, even though it was
only 4.5 deg. C.  The pointing was subsequently lost, but after
resetting at zenith it worked for the rest of the night.  I did
notice that the current for the track system was high (>1) when
I checked a couple of times.
