After moonset on the morning of October 20, there was a one-hour window of darkness before the break of dawn. Comet Hartley 2 was shining down from the zenith, smack-dab in the middle of the pentagon of Auriga and perfectly placed for a portrait. I captured this 156-second piggyback exposure at 5:06 am MDT using a 38 mm lens at f3.3 on a Fuji Finepix S2 digital camera at ISO 800. The comet was barely discernible to the unaided eye under near perfect conditions. The green comet stands out well amongst the many other fuzzy star clusters in Auriga, M36, M37, and M38.
