Another gem from the deep south (Dec about -77); the Chameleon Molecular Cloud in LRGB. Mostly a dusty region of dark nebulosity but there is some reflection nebulosity to be seen including Cederblad 110 (upper center) and Cederblad 111 (blue nebula lower center). Another standout feature is the orange V-shaped nebula just below Cederblad 111 called the Chameleon Infrared Nebula, which is a young, cool, low-mass star emitting streams of fast-moving gas that carved a tunnel through the dust. Something else I noticed when processing was a small red object at the center of the image. Turns out it's a Herbig-Haro object (HH 49-50), which are regions of nebulosity that form when narrow jets of fast-moving gas ejected from a new star collide with the surrounding gas. Considering this region is an active stellar nursery (one of the closest to Earth actually at about 600 ly) it's not surprising that a Herbig-Haro object can be found there. These objects are short lived and visibly change over the years due to their rapid movement.
Imaged over two nights at my dark sky location (Bortle 2) and, after some frame culling due to wind and some unexpected high cloud, ended up with ~2.5 hrs of good data per filter. Also, I've been told the cloud looks like a person running away from a wolf. Took me a moment, but now I can't un-see it!

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.
