17P/Holmes suddenly brightened on October 24, 2007, and has been an easy naked-eye comet for the last several weeks.
On the evening of November 5, I was shooting asteroid discovery fields and needed to wait five minutes for the search area to cross the meridian. I decided to pass the time by shooting six 60-second exposures of the comet. The result below is a stack of the six exposures, tracking the comet's motion. The mid-time is 7:10 UT on November 6, 2007.
The exposures were taken remotely at the RAS Observatory in Mayhill, New Mexico, with the GRAS-004 0.25-m f/3.4 Takahashi Epsilon E250 Astrograph.
