I forgot to mention this is my previous post, but if you look at Jack Marling's color 
photos (in AMOACP) through a DeepSky (DS) filter, the stars look white, not red. This 
is also true for Jerry Lodriguss' recent color photos through a DS on his page. Now, I 
distinctly remember an article in S&T or Astro. a few years back stating that a DS 
makes everything red on color film - stars and all. Has color film changed that much 
over the years, or am I loosing my mind (the most probable answer <G>)?
