Description

This is an interesting  HII region in Sagittarius arm ionised by the O8 V star HD 161853. The object is listed in Avedisova, Humphreys and Reed catalogs, but not as an individual nebula. The location of the HII complex also coincides with the radio source W25, and has multiple names. 

The image acquisition was done with CHI-1 Planewave CDK24 telescope from Chile, which is excellent location to image most of the Sagittarius region not visible from Northen Hemisphere.
