Dusty blue reflection nebulas Messier 78 (bottom) and NGC 2071 (top) in constellation Orion near the red arc of Barnard's Loop at left. Dark dust lanes run through the region and colour the sky brown. The tiny variable nebula known as McNeil's Nebula is below M78. Some small 16th-magnitude galaxies in the PGC catalogue are recorded amid the dust at upper right in the frame. Photographed from Alberta, Canada, on 19/20 October 2023.
