Re: [APML] Astronomy Magazine M8



Matt,
 
   Are you sure that M8 is mostly gray with a hint of red?
Every negative that I have seen of it comes out deeply cyan, indicating that a lot of red was being recorded. Even short exposures indicate the red, so it's not reciprocity failure.
Most good negative films record colors quite faithfully within major color ranges during short exposures (less than 5 minutes) so I really wonder about this... if that is a mass of glowing hydrogen gas why wouldn't it be red?
