The Luminance data was collected as a trial run with the Light Buckets 24" telescope for an AISIG Group Project. I shot the RGB with my modest equipment, a 10"LX200 and ST-2000. The Luminace data was added to the RGB in Photoshop to create this image.
NGC 2359 (also known as Thor's Helmet) is a emission nebula in the constellation Canis Major. The nebula is approximately 15,000 light-years away and 30 light years in size. Known as a Wolf-Rayet star, the central star is an extremely hot giant thought to be in a brief, pre-supernova stage of evolution. It is similar in nature to the Bubble Nebula, interactions with a nearby large molecular cloud are thought to have contributed to the more complex shape and curved bow-shock structure of Thor's Helmet.
It is also Sharpless catalog Sh2-298 and Gum catalog 4.
