This reflection nebula associated with the cometary globule CG12 in Centaurus is around 2000ly distant.
The dusty plume is fairly faint, and really needs a good deal more exposure time than the 3 hours RGB here - (yet another hopeless dark period in the Melbourne area
).
So this is a work in progress which I hope can be completed in the next month.
The image FOV is ~40' x 40'. Seeing was nothing special at ~2.6"/px (best I've had at Mt Macedon was 1.8"/px around this time last year).
