This image of Saturn was taken on the evening of June 3, 2011 between 9:28pm - 9:58pm CSDT.  Conditions were not too bad...seeing was good and transparency was average, as per our local Clear Sky Clock.  After processing the image, we discovered that focus was a little soft, but we are still pleased with the results. This image has been re-sampled to 125% to give a larger scale.
