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.

Another redo of an older data set using new techniques to reveal the structure of this dusty nebula.
The Iris Nebula is a beautiful reflection nebula lit from behind by a bright star. Although the beautiful blue core is easily visible even with regular camera lenses, it takes dark skies and long exposures to bring out the subtle ripples of dust that appear to expand from the center.
This inky nebula is a reflection nebula that is illuminated by a central star and glows blue.
Join me for a night of viewing. I observed several nebulae (the Iris Nebula, the Dumbbell Nebula, and the Eagle Nebula) and the moon all night until 3am when the planets Saturn, Mars, and Jupiter appeared in that order.
