About this celestial object
A second look deepens the first sketch of the distant target in the shallow light near the horizon.
Distant systems often reveal only a hint of structure — part of the appeal of deep-sky imaging at short focal length.
28 frames at roughly 9° altitude and 60% humidity refine the rendering over the first trial.
The 250 mm lens at f/5 frames the field evenly and keeps the stars tight.
