Observations of Sunday, Oct. 2, 2011

A very good evening for observing with the 14 inch.  Found C/2009 P1 (Garradd).  Its position is a little different from that in the IAU Minor Planet Center ephemeris, but only by a minute or two in declination.  The comet seems a little fainter--about +8.5.  Sky contrast was quite good and I thought I could make out a faint tail.  Looked at some of the old standy objects:  Albireo, M13, M92, the Ring Nebula (which was wonderfully visible, floating almost in 3D against the background of space.  The Dumbell Nebula was also beautiful, with the dumbell shape clearly visible.
