1h 30min of integral RGB exposure of a part of the Western portion of the Circinus molecular cloud complex (G317-4) filled with multiple Herbig-Haro (HH) and nebulous star (vBH) objects - captured remotely using Telescope #3 (ASA-N D = 0.5m f/3.8, FLI ProLine 16803) system of ChileScope observatory on Feb 20, 2023.

This region is well studied with much details provided in the article John Bally et al 1999 AJ117 410 (DOI 10.1086/300672) [1-3]:

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.
