Comet Hartley in Cassiopea Midnight October 1

LRGB composite of Comet 103P Hartley as it was moving last night located about 2 degrees south east of Alpha Cassiopeae. Even during this short exposure totaling 25 minutes (10 mins for luminance and 5 minutes each for RGB) the comet managed to move almost 2 arc minutes. This can be seen in the elongated shape of the comet inner coma which is due to its motion. The comet sports no apparent tail. The outer coma in this picture is about 15 arc minutes in diameter or half the size of the moon.
