Taken under very problematic weather conditions. High clouds were present all the time and fog on the ground added to it. 76 OSC subframes were lost to the clouds and so were 3 Ha subs. As the low image scale is forgiving I was able to correct some of the blur by deconvolution. Next the telescope suffered from pinched optics which was corrected after the shot. In my eyes it is a surprisingly good result for the bad conditions.
