Celestron 9.25-inch Schmidt-Cassegrain telescope on a fork mount, 3-second exposure at f/10 at ISO400 using a Canon 350D Rebel XT digital SLR camera at the Cassegrain focus. The image was cropped but otherwise no image processing was applied.


In this image the comet appears perfectly round with an inner coma that is offset from the tiny nucleus visible at the center. A faint dark arc is seen to the upper left and extends approximatly 180 degrees around the interior of the coma. The bright comet was growing in size and noticeably larger than the previous night. The comet's round shape was even visible in the telescope's 8x50mm viewfinder.
