Object Information                                            Imaging Details

Thor’s Helmet is 15,000 light-years away in the constellation of Canis Major. The nebula’s core is powered by an extremely massive and unstable star known as a Wolf-Rayet. This star is currently in a pre-supernova stage of its stellar life cycle.

This is a combination of Ha and OIII narrow band images taken from my front yardt. The Moon was just rising as I began shooting the O3 subs. I was hoping for more subs (especially more O3), but tracking error increased as the object crossed the meridian. I had to throw away several subs.

This object was imaged from my fronr yard in Las Cruces, NM.
