Description

Thor's Helment (NGC 2359) is an emission Nebula in the constellation Canis Major. It is about 15.000 lightyears away from earth and expands at a speed rate of ca. 25 km/s.

The light emitting bubble is exited by a Wolf-Rayet-Star which that emits hard radiation that blows the outer shells into the space.

Imaged from my balcony with a TS 130/910 mm refractor and an ASI1600mmpro camera.
