Sure alpal, Please have a go Perhaps write down what are your steps too for us novices to follow!

3 raw files Ha, O and S are at Astrobin Rawdata http://www.astrobin.com/rawdata/publicdatapools/9/

I had to join AstroBin to download it so I uploaded my result there too.

I had to do a lot of stretching & also sharpening at 4 pixels to get any detail out of it.
Maybe others can try?

cheers
