The Pacman Nebula, located in the Perseus arm of the Milky-Way. 9200 light-years away, and interestingly is nearly 1000 light-years above the plane of our galaxy. It spans almost 80 light-years across. The star cluster at the center labeled IC 5090 energizes this wonderful object.

It was discovered in August of 1883 by E.E. Barnard who described his find as "a large faint nebula, very diffuse."

Imaged using the STC Duo Narrowband Filter under adverse moonlight conditions.
