Sharpless 2-101 region
Emission nebulosities in Cygnus
Uploaded 9/11/26

Centered on Sharpless 2-101 the Tulip nebula in central Cygnus, this large field reveals that east of the Tulip we have wreaths and rings of hydrogen gas, excited by hot blue stars in the cluster NGC6871 right in the middle. The right side of this shot is dark due to extensive dust obscuring the gas from view. Look carefully on the left side to see a greenish wisp in front of the eastern edge of the red ring bubble. Thats the Wolf-Rayet star WR132, one of the most challenging targets to shoot in the northern sky.
