This is 100 minutes of luminance data of the M78 reflection nebula. Taken from iTelescope New Mexico observatory. Messier 78 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. For those wondering about the bright patch in the lower left corner, it’s a hint of the Flame Nebula which is near the infamous Horse Head Nebula.
