NGC1491 is an emission nebula in Perseus. It is about 10,000 light years away. Veteran astrophotographer Bill Snyder shot this photo in early 2013 from Heavens Mirror Observatory SRO in California’s Sierra Nevada Mountains. He used a Planewave 17 inch telescope with an Apogee U16 camera, as well as a Paramount ME mount to capture the image. (Image credit: Bill Snyder Astrophotography)
