NGC 2359-Thor's Helmet Narrowband

NGC 2359, Sharpless 2-298 or Thor's Helmet, is an emission nebula situated in the constellation of Canis Major. The central star is the Wolf-Rayet star WR7, an extremely hot star thought to be in a brief pre-supernova stage of evolution. It is similar in nature to the Bubble Nebula but interactions with a nearby large molecular cloud are thought to have contributed to the more complex shape. It lies around 11,960 distant.
