NGC7023
About this celestial object
The Iris Nebula NGC 7023 reveals fine dust lanes in the scattered light of an embedded star.
As a reflection nebula, it scatters starlight off fine dust; dark filaments trace patterns against the Milky Way star field.
Humid, horizon-hugging air challenged contrast—250 mm focal length and careful stacking bring the structures out.
Imaging in the red spectral band emphasizes the dark clouds over the scattered light.
