103P/Hartley2 Stack

Sedro-Woolley, Wa.

Comet 103P/Hartley2 in the evening of October 13, 2010 Local time. In the constillation Perseus
Image Center at about 3h56m26.06s DE:+52°15'29.1"
This comet makes its journey around the Sun in about 6.47 years.
Its distance from earth is about 0.127 AU, 11,805,387 miles, (92955807 miles per AU) at the present time.
The sky was rather troublesom but around here that is fairly normal.
The nucleus of the comet was about 10 pixels in length during the five minute exposure so I tried to stack on the leading part of the comet.
