NGC 6188

Situated in the southern reaches of the Milky Way in Ara, is an interesting patch of bright and dark nebulosity surrounding a small open cluster. The nebulosity is NGC 6188 and the cluster is NGC 6193. The cluster is fairly weak, containing only a few scattered stars, however the brightest are all blue giants which contrast well with the rich surrounds of the Milky way. The nebula is difficult to observe visually, but can be detected with an 8" telescope if the skies are dark. The region deserves to be better known, as it probably would be if it were more accessible to northern hemisphere observers. The faint patch of nebulosity at the lower right edge of the image is the faint emission nebula RCW 106. The rich cluster between it and NGC 6188 is NGC 6167.

Near the right hand edge of the photograph below is an interesting object, a bright blue star with a bright red patch on either side. This is a mass-loss star, sometimes designated as a planetary nebula, NGC 6164/6165. The star has ejected a shell of material but not uniformly, with the bulk of the material being ejected in the equatorial plane of the star, where we see it as two arcs. These are readily visible in an 8" telescope.
