I put together a quickie ET Cluster image I shot during late January, 2013 in poor seeing. I am not real happy with it as I think I processed my luminance stars too hot before layering on the RGB. Therefore, the LRGB stars are a bit too burned, not smooth and I lost some of the subtle blue star coloration. I’ll reprocess with less aggressive Lum in the future. Look closely and you will see some galaxies between the cluster stars.
