This winter I spent nearly 50 hours imaging this glorious reflection nebula from my private observatory. Nebulae like this one are very difficult to capture. They need extremely dark skies to really bring out the dust surrounding them. Only recently was I able to process all of the data captured on it.
Messier 78 is located in the constellation Orion, at a distance of 1400 light years away from Earth. This is the first time I have imaged this object and always seems to be ignored among the other great objects in the Orion constellation. M78 is best viewed during winter, is magnitude 8.3 brightness, and can be viewed with binoculars just above Orion's belt.
Messier 78 is primarily a reflection nebula, which means it is composed of interstellar dust that reflects the light of nearby stars, thus creating its unique glow. Within M78, over 40 young stars less than a million years old have been identified, making it a stellar nursery where new stars are being formed. The nebula's blue tint is characteristic of reflection nebulae and is due to the scattering, or reflection, of shorter blue wavelengths of light by the dust particles.
