I processed the stars and nebula separately in PixInsight and Photoshop. Just brought up the light and color mostly.

This is M97, the Owl Nebula. It's a small, faint "planetary nebula" (actually a misnomer) in the constellation Ursa Major. I photographed it for nine hours last night and this morning. 108 images of five minutes each. This is a stack of all of them.
