After a night of imaging the Pleiades I had only an hour left until dawn, so I decided to point my telescope at Orion's sword and capture the Running Man and Great Orion nebula. I used my sulfur, hydrogen, and oxygen narrowband filters and took 4 5-minute exposures with each, then combined to produce this photograph.
