Also featured as the 23 December, 2021 AAPOD2! (https://www.aapod2.com/blog/the-reaper-ldn-673-684)

My primary target from the 2021 Star Party - LDN 673 appears like a swirling mass of tentacles, and LDN 684 is included (to the upper-right), fans of the Mass Effect series may notice it appears like the shadow of a Reaper, leading to my title. As this nebula complex (600 l.y. distant) is located within the main band of the Milky Way, the area is filled with golden and red starlight, making the darkness of the nebula easily stand out and providing the rare blue stars with brilliant color contrast.

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.
