Target & processing
Eighteen hundred years ago this light left a bird made of hydrogen. It stands in profile against the Cygnus dark, its beak of dust turned toward a gulf of nothing, the same black river that separates it from a continent-shaped neighbor, both of them shores of one drowned cloud.
My first target with multi-sessions acquisition (with an astro camera).
