Lets talk about Noise.


I have a few questions regarding noise. I find my 1000d to be quite noisy even when stacking multiple images.

Last night I took 4x5min subs of Cent A @ iso 800, and notice that when I stacked them the noise didnt really get any better. Now, on to my questions.

Is 4x5min the same as 5x4mins in terms of exposure it is but is it the same for noise reduction?

Would I have been better doing shorter and more subs?

I assume that the more subs you take the better what is the normall amount that people take?

I'll post a pic of what I'm talking about in a second.
