NGC6888 bi colour - a photo on Flickriver

NGC6888 bi colour

            Crescent Nebula in h-alpha and OIII, bi colour processing.
Only about an hour of each filter due to poor sky quality, and lack of clear nights, but i managed to squeeze an image from it so it's definitely a win. :) 
Hoping to add more, although not sure when it'll happen :P ...... good ol' UK skies! 
Data was combined in Ha/OIII/OIII for RG and B Channels respectively, in photoshop. Some noise reduction at various stages to compensate the sparse data, not entirely successful....... :P

ED80 - QHY163M - Optolong ha 7nm, baader OIII filters. 5 min exposures x apprx. 12 each filter.
