"This full-spectrum image of the Spaghetti Nebula unveils the faint and elusive nature of this supernova remnant (SNR), hidden behind a vast cloud of dust that obstructs its emission light. To enhance its visual appeal, Shaoyu Zhang dedicated considerable time to capturing OIII data, intensifying the blue and green hues, while allowing SII and H-alpha to support high dynamic range stretching for added depth."
