I didn't think the clouds were going to cooperate for tonight's conjunction of Comet Garradd and globular star cluster M71 in Sagitta, but the skies cleared around midnight. The attached image is a stack of two one-minute exposures taken at 1:46-1:48 AM MDT on 08/27/11. I used a Celestron C102-HD telescope and a Nikon D700 digital camera set at ISO 12800 for the shot from Stagecoach, Colorado. At the time of the exposure, the comet and the star cluster were separated by only 23 min of arc, both glowing at about 8th magnitude.
