The most interesting portion is immediately below the two blue stars centrally.

N6729 is, according to wikipedia, the fan shaped Caldwell 68 nebula below the blue reflection nebula due to premain sequence R Coronae Australis (Binary B and Red Dwarf). And it is variable like Hubble's and Hind's variable nebulae! A star shining through dust like a lighthouse beam, changing on quite a short time scale.

The comma-shaped body beside it is even more interesting, It is HH100 (Herbig-Haro Object 100) and is caused when a narrow jet emitted from a newborn star hits nearby gas and dust at high speeds.

https://www.sciencedirect.com/topics/physics-and-astronomy/herbig-haro-objects is an interesting article left side of page column about mechanisms.

HH111 shot by HST got a lot of publicity because so beautiful -https://www.sciencetimes.com/articles/33164/20210831/sword-heart-hubble-space-telescopes-wfc3-captures-herbig-haro-object-hh111.htm

I would love to try for more detail but I'm not sure my Celestron C8 is up to the job.

https://www.astrobin.com/mvjjb9/?nc=user is really interesting!!!! (53h RCOS 10"!!!!) COMMENTARY EXCELLENT

https://www.astrobin.com/7b7vi6/?q=HH100 is very sharp and impressive for 15h exposure.

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.
