I have processed this before using Paddy Gilliland's superb data

I was not that happy with my last effort, so I thought I would try again. The data this time was:

Ha 5nm: 11x1800" -20C bin 1x1, 600" Ha, 300" Ha and 60" Ha, OIII 5nm: 12x1800" -20C, OIII 5nm: 6x60" -20C and SII 5nm: 6x60", SII 5nm: 10x1800" -20C. The shorter subs being used with HDR composition for the core. I am not too sure about the colours in this, especially round the running man, but I did my best...
