Description

There's not a whole lot of nebulae to image early in the night this time of year so I bring you this oddball. This was mistakenly included in Sharpless' catalog of HII emission nebulae. It is actually a molecular cloud illuminated by the integrated flux of our galaxy. It has been determined that there is no star formation occurring in this molecular cloud.
