Philipp Keller and Christian Fuchs (who did the image processing)

for this picture we combined an older B&W-Image with some color data of the 1.2m Trebur telescope. The seeing was bad for the color data but it turned out to be good enough to make a LRGB with the L-channel of the Pollux telescope where we had good seeing.
This objects needs good to very good seeing and maybe the AO7.
