Comet Hartley 2 on October 9, 2010
Finally managed to see this one!
Light polluted Zeist, the Netherlands, but this night was as good as it gets.

Single frame post processed in Adobe Photoshop Elements in the early morning of 10-10-2010. Stacking of frames was kinda useless, what with the comet moving this fast that it would jump from one to the other frame.
