Taken from my backyard observatory in Canberra with a 12.5" RCOS Ritchey Chretien at F9 and a SBIG STL6303E CCD camera. The image was acquired on 4 July 2010.
This is a LRGB exposure with L=70, R=60 and G=B=70m. All exposures unbinned. Astrodon NIR filters were used. R, G and B are assigned to bands peaking at 850, 830 and 750nm respectively. L is infrared luminance with zero pass shorter than 700nm.
