Combination of 20, 3 minute images with an H-alpha and an SII filter,
and 10, 3 minute exposures using an OIII filter.
SBIG ST-8XE CCD. 5" f/5 refractor at prime focus.
NGC 6589 and NGC 6590 are two reflection nebulae in Sagittarius, almost halfway between M8 and M17. The surround stars that are members of the weak open cluster, NGC 6995. They are visible as very small and faint whitish patches surrounding two of the stars in the centre of this image. The reason they show up so weakly was that the image was taken using narrow-band filters. I used them because I was more interested in the H-alpha emission in this region. The very bright patch of emission just above centre, is IC 1283/1284. The large area at the bottom right is part of Sharpless 2-35.
