OT: comet 2009 P1 Garradd with the new 1.4/85 mm lens (updated)

Yesterday evening (30 Aug 2011) started reasonably clear, so I set up the small Meade ETX-70, put the Canon EOS 450D with the new Samyang 1.4/85 mm lens piggyback on it, and made a series of images of the Sagitta-Vulpecula border area, where comet 2009 P1 Garradd is currently located.

Sky conditions were variable. Out of 97 images (of 10 seconds exposure each), I selected the 34 best for the stack below. The comet (small, but with a clear tail) is in the center, parts of Sagitta with M71 are at left, the "coathanger" cluster is at right:
