NGC 7023 Iris Nebula
NGC 7023 Iris Nebula
This is a neat little reflection nebula in Cepheus that I captured with Hydrogen Alpha and RGB filters on the RASA 11. I don’t normally take much reflective nebula type images, but the dark dust structures and gases are not energized enough to consist of much emissions, so they reflect the star light around them.
