Sh2-122 - Reflection Nebula in Pegasus

Click on the image to see it at 2x resolution

Sh 2-122 is likely a reflection nebula illuminated by an embedded but unseen star and associated with the molecular cloud MBM 55, at a distance of 150 pc. Markab is just out of the frame hence the intrusive spike of light at the top. Sigh.
