Sh2-115
"The Wolf" Nebula
I
call it The Wolf, but no one else does. You can see the wolf head in
the center of the image, stalking a squirrel at the lower-right. The
wolf is Sh2-115 while the squirrel is Sh2-112. The small object halfway
between the wolf and the top of the image is Sh2-116, also
cataloged as Abell 71. It was originally thought to be a
planetary nebula, but after H-II was detected it is now
considered an emission nebula. The wispy-looking structure at the
top-left is mostly DWB 192, and there are several other
emission nebula within view. All objects are 5,500 to 7,500 light-years
from Earth. North
is at the top-left.
