103p/Hartley2

Comet Hartley in Cassiopea Midnight October 1

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.

Comet 103p/Hartley2

This video was taken with my newly purchased Astrotech 111EDT telescope, Starlight Xpress ccd SVXF-H9 and guider, on a CGEM mount, 37x60 sec images combined of Comet 103p/Hartley2. Wait and watch as the comet moves between two stars and ends past another bright star (I did not get their names). Taken from Whiting, New Jersey
