The Running Man Nebula (Sharpless 279)

The Running Man Nebula, Sh2-279, lies alongside the famous Great Orion Nebula, M42, and both appear
in the asterism known as Orion’s Sword. It lies around 1,500ly away, and is a combination emission (H-II)
and reflection nebula. In fact, the nebula has been catalogued in the New General Catalogue as NGC 1977
(emission), NGC 1973 and NGC 1975 (reflection) nebulae. It was first recorded by William Herschel in 1786
(NGC 1977).

Sh2-279 is observable through binocualars and small telescopes as an indistinct hazy smudge. The
“running man” dark nebula formation that gives it its common name requires photography to see it
properly. Thus, it is a favourite of astrophotographers where it is frequently photographed along with
M42.

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.
