| Fifteen thousand light-years away in the direction of constellation Canis Major, Thor's Helmet is a complex nebula illuminated by a bright rare Wolf-Rayet type star. High velocity stellar winds from this energetic star compresses, excites, and illuminates surrounding gas and dust to create a bubble of illumination, similar to the process seen in the Bubble Nebula. This unusual object is classified as NGC 2359. This image combined 120 minutes luminance exposures using a Hydrogen-alpha filter with 30 minutes each of red, green and blue exposures. An ST10XME camera was used through a TEC 140mm refractor at my new observatory. Thor's Helmet is probably too faint to be imaged well with my telescope, but I couldn't resist trying. |
