Swan M17 Question. from QLD Astrofest

Attachment 248114The Swan has always been one of my (many) Favourites o here's my dilemma. I used a UHC filter thinking that it would enhance the Nebulosity ( which the physics says it does) however the old problem of the colour balance skew appears.Here are 2 options that I have post-processed in Gimp (probably different work flows) . At this point in time I think the mono version is the best 245 lights . I also used the 'Best percentage " in DSS which used 188 lights instead of total of 245 which reduced star bloom .. I suspect I need to get some unfiltered RGB data to add???? All shot at 3.2 Sec at ISO3200.
