The Seagull Nebula is a large emission nebula complex straddling the border of Monoceros and Canis Major, roughly 3,650 light-years away and spanning about 100 light-years, or some 3 degrees on the sky (about seven times the apparent width of the full Moon). The complex takes its name from its wing-like overall shape: the nebula's âhead,â a compact, bright region with its own embedded young cluster, is often cataloged separately, while the fainter âwingsâ carry the IC 2177 designation and the open cluster NGC 2335 sits near the nebula's northern end. Given its large apparent size and relatively low surface brightness, it is best suited to wide-field imaging with shorter...
