Messier 78 or M78, also known as NGC 2068, is a reflection nebula in the constellation Orion. It was discovered by Pierre Méchain in 1780 and included by Charles Messier in his catalog of comet-like objects that same year. Reflection nebulae are clouds of gases that are lit up from behind by bright stars. M78 is about 1,350 light-years distant from Earth. This image is a stack of exposures collected over several nights while we were camping in Borrego Springs over a new moon weekend and represents 5.5 total hours of exposure time.
