This is the Cocoon Nebula (IC 5146) area with the Messier 39 cluster to the right (barely standing out here) and the NGC 7209 cluster to the left; with the dark nebula B168 (aka the Cigar Nebula) between the Cocoon and M39.

The 9º by 6º field of the 135mm lens used simulaes the field of view of binoculars.

Taken Sept. 13, 2007 for stack of 4 x 4 minute exposures with 135mm L-series lens at f/2.8 and Canon 20Da camera at ISO 800. Reprocessed in 2025.
