Thor’s Helmet

NGC 2359 (also known as Thor’s Helmet) is an emission nebula in the constellation Canis Major. This is a very difficult deep sky object to capture, for people in the Northern hemisphere, due to its low elevation and low surface brightness. I waited for a good transparent and cold night to capture this image. The temperature at the time of capture was -8 c.
