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.

Triad filter used for Luminance channel: (T)RGB. It works!

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
