Thor's Helmet Nebula
This was a tricky one to image as it was quite low and hiding behind the trees for part of the imaging session. However determination got the better of me and I stuck it out till gone 4am in the morning to capture this one. I have wanted to capture it for some time and was surprised at how faint it was but definitely worth it
NGC 2359 (also known as Thor's Helmet) is an
emission nebula[3] in the constellation
Canis Major. The nebula is approximately 15,000 light-years away and 30 light years in size. The central star is the
Wolf-Rayet star HD 56925, 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.
