	Imaged on 2011 August 28 against the stars of Sagitta, when near M71 (upper right); one of a series of 60sec exposures at ISO800, using a Canon 450DH camera and 300mm f/2.8 lens on a Synta NEQ-6 mount tracking the stars; field of view 1° x 0.7° approx, N to top.
	A series of 44x60sec exposures at ISO800, using a Canon 450DH camera and 300mm f/2.8 lens on a Synta NEQ-6 mount tracking the stars; field of view 1° x 0.7° approx, N to top. Images were aligned on the comet nucleus, star trailing indicates the comet's motion against the stars over the 45 minute duration of the series.
