Hi all, here is another often overlooked patch of sky with a very interesting dark nebula over a bed of stars. Sandqvist 169 snakes across a glittering field of bright Milky Way stars in the constellation of Circinus. It forms the western part of the giant Circinus Cloud complex, which filamentary appearance is likely to be the result of multiple outflows from young stars, whose formation might have been triggered by a supernova that exploded in close proximity to the cloud. The Circinus Cloud has been the subject of very few detailed studies, hence its distance is extremely uncertain and is estimated to be 2275 light years.
The Circinus Star Forming Complex
This one is a 26+ hours HaLRGB composition, even if there is very little Ha but I hoped to detect some HH objects, but in fact I didn't succeed.
The dark silhouette of the nebula reminds me a kind of black devil flying, it is only me seeing this?
