IC443
About this celestial object
A brief glance brushes the Jellyfish Nebula—just enough for a first glimmer.
IC 443 is a supernova remnant with fine, fibrous filaments—photographically striking in H‑alpha, visually more demanding.
At the very low altitude, this single exposure shows only a hint of the nebula in the winter star field.
With 250 mm f/5 the wide field shows the context; longer integration would bring the filigreed arcs clearly into view.
