This image captures Sh2-224, a faint emission nebula formed from the expanding shock front of an ancient supernova remnant in the constellation Auriga. The delicate filaments trace ionized hydrogen and oxygen energized by the original stellar explosion, now dispersed into the surrounding interstellar medium. What appears as a translucent crimson shell is actually a complex network of swept-up gas and magnetic structures, revealing how massive stars recycle material back into the galaxy and help seed future generations of stars.
Recorded over four full nights from Bürmoos (Salzburg, Austria), this 40-hour integration blends LRGB with SHO to emphasize both stellar color and the nebula’s subtle ionized layers. The fine arcs and wisps visible throughout the field highlight the turbulent interaction between the remnant and nearby molecular clouds, while the dense star background underscores how quietly this relic drifts within the Milky Way. Stacking the best 80% of the data preserves faint outer tendrils, giving a rare, high-contrast view of a structure that is usually lost in the noise.
