Orion Nebula
The Orion Nebula is one the brightest nebulae in the night sky, and one of the most photographed objects in the night sky. The intense star-formation in the region results in turbulent motions in the gas, and photo-ionising effects on the gas by massive stars can be observed in narrowband filters with the Nieves Observatory.
