The M78 Nebula or NGC2068 is a reflection nebula that can be found in the Orion constellation. This constellation is well known to have huge HII regions with strong emissions.
In this image we can see part of the Orion Molecular Cloud Complex: the Barnard’S Loop. Emission, reflection and dark nebulae are present in this wide field. The Orion Cloud lays around 1,500 light years away from us. The most popular object in this region is M42, also called the Orion Nebula, one of the brightest deep sky objects.
17 Herbig-Haro objects can be found in the M78 structure. These are patches of nebulosity associated with newly born stars.
The image shown above has been composed using new data from last week’s acquired with my new FSQ Takahashi dual setup. LRGB broad band filters together with the Hα narrow band filter has helped me to show the hydrogen emissions from the Barnard’s Loop.
