Hi all,

Quick question: I have taken 100 Bias frames with Maxim. And now I want to combine them with PI.

What's the best method to combine Bias, Darks and Flats? average, Median ..?
To do this I will just use the ImageaIntegration process, right?

Hi,

I generally combine these with a sigma reject just in case there's a cosmic ray hit. So with PI I use Average with Sigma Clipping pixel rejection.

For that number of images, a sigma reject and averaging should yield better SNR.

Thanks guys.
Okay then, will use Sigma reject.

I also plan to start creating a dark library. Will use the same method.
