Sh2-278 sits halfway between M 42 and the Witch’s Head Nebula in the Orion constellation, about 2.5° north of Rigel. It has a triangular structure that is prominent in H-alpha. This structure is surrounded by several faint reflection nebulae. These include LBN 964 to the east, LBN 945 to the northwest, and LBN 937/LBN 942 to the north. It is an incredibly pretty and unique object, but it is very faint. The combination of dim molecular cloud with ionized hydrogen makes it challenging both to capture and to process.
The glow here may be extended red emission. It sits just off the edge of the Orion A molecular cloud. This is the cloud containing M42. However, it is not clear if it is a remnant of that group or a distinct cloud.
Imaged from my driveway in the hills of WNC. Session management with Astro Photography Tool (APT 4.60), image processed manually with PixInsight processes.
It’s referred to as the Wolf Head Nebula, but I don’t see it.
