[APML] Final Halpha composite of Cygnus



Title: Message
Hello all,
I went back and revisited my initial experimentation with some Halpha exposures on E200.  I thru in some old PPF exposures to help add some color balance to the reds.  The PPF was shot at a 165 focal length vs. the 105 for the other shots.  Some interesting colors.  I tried the HHRGB method, but the halpha shots were just not good enough to really serve as a luminance.  They only worked as a supplement to the red channels in the other films.  Comments appreciated.  Other details at website.  Another learning experience to say the least.
