NGC 6188 - The Fighting Dragons of Ara
NGC 6188 is an emission nebula about 4,000 light years away in the constellation Ara. One of my favourite targets and I think my best version of it.
The jagged ridge running through the centre of the frame is an active star forming region where dense molecular clouds are being sculpted and eroded by intense radiation from the young massive stars of the nearby cluster NGC 6193, visible as the bright blue grouping in the upper left.
The warm orange regions are sulphur emission from denser compressed gas, the blue zones are doubly ionised oxygen being lit up close to the hot young stars, and the green transition zones in between show where the chemistry changes from one to the other.
