Description

NGC2359, Thor's Helmet, Celestron 9.25 XLT SCT, taken using Nebulosity3, darks subtracted with MaximDL, stacked and further processed with Nebulosity 3, more processing with GIMPshop in Ubuntu. Approximately 18 hours of exposure.

Thor's Helmet is about 30 light-years across. The helmet is an interstellar bubble, blown as a fast wind from the bright, massive star near the bubble's centre sweeps through a surrounding molecular cloud. 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. The nebula is located about 15,000 light-years away in the constellation Canis Major.
