Re: Canon Rebel XT, Nikon D50 or Pentax K100 best?



Which of these is most sensitive (highest S/N) for low light
astronomy?

I had the chance a couple of months ago to do some Milky Way shots
with a D50. The images were quite a bit noisier than my 300D. Since
the 350D (XT) is less noisy than the 300D, I'd say you don't want the
D50. I don't know about the Pentax.

Two different opinions, I was afraid of that!
Were these Milky Way shots done with the same lens?
The ISO, exposure length, temperature all affects the S/N.
Perhaps the other sources are measuring the D50 noise with the median
filtering in effect?
