MDM Observatory 2.4m Telescope Observing Report for 2010 Sep 28

Observer(s): S. Lepine
Institution(s): AMNH

Instrument: Direct + Nellie

Worked for 7 hours (off and on through the night)
Conditions were Non-Photometric most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Beg: Overcast, Winds Calm
   Mid: Seeing 1.5 arcsec, Patchy Clouds, Winds Light & Variable
   End: Seeing 1.7 arcsec, Patchy Clouds, Winds Light & Variable

Observing Summary:

Difficult observing conditions with many bands of
patchy clouds veiling the sky at times. Also seeing
was OK but not optimal. Just good enough for the astrometry
to be decent. Observed 16 parallax targets.

Nellie behaved without any trouble. This confirms that
the problems experienced last night were indeed due
to the Echelle camera itself.

The new guiding system with the Andor camera is
easy to use and works like a charm.
