      Wouldn't that be color correction? The wavelengths change because of the doppler effect I thought. : robosextoid

  Hijack. Does anyone do night sky photography? I bought my first DSLR and wondered how cool it would be if I could do some long exposure shots of the sky at night. What kind of equipment is required for it, how difficult does it get?
  
  One day I'm going to drive to the nearest dark sky park (in central PA) and shoot stuff.

      it's faint, but you can see color. the photography just gathers more light, so you can see it better. : drucifer
