Forgot to mention that I think this may be a valid assesment. Supra is
the only film I've used for several years now and has been a solid
performer, and it will continue to absorb photons for about as long as
you can leave the shutter open. However, now that I am going after
fainter objects, I'm starting to notice weakness on blues, and fainter
emission nebula. There was not a lot of blue on the 3+ hour shot I just
did on M45. Don't understand why it's that way, but it is. Most have
missed the post you mentioned.
