M36 and M38, March 28, 2008. Two open clusters in the constellation Auriga, M36 and M38 are the concentrations of stars in the photo. Both clusters are about 4,100 light years from Earth. My plan for taking this photo was to capture a close pass of the comet 46P Wirtanen, which is just half a degree to the lower right of the upper cluster, M36. The comet had faded from view however by the time of its pass, and it is just barely visible as a faint greenish smudge near the cluster.
