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.
