Eagle Nebula, M16, in the constellation Serpens. An OSC camera and an Optolong L-Extreme filter.
The starless image was created with StarNet in PixInSight. This allowed better processing of the nebulosity while preserving the stars. Then I added the stars back in with Pixel Math.
Imaged from my backyard in upstate New York under Bortle 3 skies.
