Thor's Helmet - NGC 2359

Latest image from the observatory. #NGC2359 #ThorsHelmet Hey folks....Been working on this one for a while, waiting for the moon to go down so we could get the needed RGB data. This NGC 2359 The Duck Nebula....Aka Thor's Helmet. Pretty pleased with data, not so much with processing. The harder the objects get the more demanding the processing gets... and still have a ton to learn....But getting there. Will reprocess when have a little more time to devote to it..... Second image is a slightly cropped image.... Hope y'all enjoy!....and Merry Christmas!

The nebula is approximately 3,670 parsecs (11.96 thousand light years) away and 30 light-years in size. 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 and curved bow-shock structure of Thor's Helmet. It is also catalogued as Sharpless 2-298 and Gum 4. The nebula has an overall bubble shape, but with complex filamentary structures. The nebula contains several hundred solar masses of ionised material, plus several thousand more of unionised gas. It is largely interstellar material swept up by winds from the central star, although some material does appear to be enriched with the products of fusion and is likely to come directly from the star. The expansion rate of different portions of the nebula varies from 10 km/s to at least 30 km/s, leading to age estimates of 78,500 - 236,000 years. https://www.instagram.com/p/B6cQr9MpF4a/?igshid=yfnjj66u22tn

Thor's Helmet / NGC 2359

Also known as NGC 2359, Thor's Helmet is a nebula found in the constellation Canis Major. As seen in this recently released picture from the Cerro Tololo Inter-American Observatory in Chile, the cosmic cloud of dust and gas is being shaped like a winged helm by outpourings of radiation from the massive stars inside.
