Description

Sh2-29, Gum 75, IC4685 

A triangle with the Lagoon and the Triffid, I have photographed it a few times.

It is said to be illuminated by an O star, HD 165921 (in the centre of the image). Bow shocks (10 o'clock to the central star), delicate dark nebulae tracing across the foreground, some larger, darker dark nebulae tracing an outline, and a myriad of stars from its position in the thick of the milky way.
There is blue reflection nebula (not shown), emission nebula (what you see) and dark nebulae all present.
