A week or so ago I posted an image of the Norma Cluster. This was a work in progress comprising only Lum. It is found here: http://www.iceinspace.com.au/forum/showthread.php?t=123679
I've added to the Lum as well as taking some RGB as well. The attached represents just under 3 hours Lum and 1 hour each of RGB. Lum was unbinned and RGB was binned x2. Taken with STX16803 mounted on PW CDK12.5.
I'm sort of happy with this. The RGB has added a bit of interest - as always, I've souped up the colour a bit more than most. But is still not that fascinating a field. I started on this target just to fill in some time before my main target and wouldn't have otherwise selected it to image. But its ok.
Processed in PI - just stretched, adjusted with Histogram Transformation, adjusted saturation and a tweak with ATWT.
A larger res image can be found here:

The fount of all knowledge - Wikipedia of of course - provides the following by way of introduction: The Norma Cluster (ACO 3627 or Abell 3627) is a rich cluster of galaxies located near the center of the Great Attractor and is about 68 Mpc (222 Mly) distant. Although it is both nearby and bright, it is difficult to observe because it is located in the Zone of Avoidance, a region near the plane of the Milky Way. Consequently, the cluster is severely obscured by interstellar dust at optical wavelengths. Its mass is estimated to be on the order of 10^15 solar masses.
Comments and criticisms welcome
