Sh2-129 and Ou4

Link: http://www.jthommes.com/Astro/Sh2-129_Ou4.htm

This image is a 2 panel mosaic of Sh2-129 and one panel of Ou4. It shows the emission nebula Sh2-129 (also known as LBN 449, Ced 190) and the outflow nebula Ou4. The blue Ou4 is sometimes called "The Squid" and the red Sh2-129 is sometimes called "The Bat." Ou4 is said to be embedded in Sh2-129 - evidence of this is the bright edge of the southern lobe of Ou4 beginning to impinge the denser Sh2-129. This image field also shows three LBN objects (the afore mentioned LBN 449, LBN 453, and 445) as well as some dark nebulae from TGU and Dobashi. These objects and some of the brighter stars are identified in the annotated image.

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.
