Horsehead and Flame Nebula in Ha

I was not planning on imaging this as I did it just last year and really want to go after the Witch Head Nubula.  However, it was finally clear, the temperature was somewhat tolerable, and the moon was out so I decided to image this gem again.  I was not totally happy with my image from last year as the Flame Nebula appeared to have the same color the Horsehead Nebula.  I believe this was a result of using the UHC filter.  It did bring out a great amount detail but I think it messed up the color a bit.  This time around I will try out my new Baader Neodymium Moon & Skyglow Filter for RGB data and combine it with this Ha data.

I have been converting my raw exposures to tiff and then stacking them in DSS as I get better star fields, however, I believe I am getting better nebula detail by stacking the raw Ha exposures in DSS. It would be great if there was some photo expert who knows why and what the best way to process these but after doing this stuff for the last few years I believe there is no "best" way.
