I'm learning how to process images with delicate and dusty features. I remembered how much dust I saw in an old photograph of the Iris Nebula, so I tried it out. This is the 3 hours of 60-second exposures with my Sony Alpha mirrorless (unmodified) camera and Samyang 12mm f/2 lens. And my best effort to process it all.
See where this image is located in space via the WorldWide Telescope.
