M78 (NGC2068) is a faint reflection nebula about 2.5 degree NE of Altanik (zeta Ori) with a size of 8 arc minutes. The nebula is fairly striking because vast dark nebula conceals stars around M78.
You can recognize another reflection nebula of NGC2071 in 20arc minutes northeast of M78 with almost same size, actually both nebulae have been made from same gaseous matters that are divided by dark nebula.
