Thor's Helmet (NGC 2359) is an emission nebula in the constellation Canis Major. It's over 30 lightyears across, and 15,000 lightyears away! A very hot giant star powers this mass of glowing gas!

This is my first hybrid image where I mixed narrowband data with RGB. The OIII here is off the charts and much stronger than the Ha. The red doesn't need much help, but the OIII really brought out a lot in this image.
