Description

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!
