Thank's If I only gain 0.45% SNR then I didn't hat to stack them at all. And if I fiddle with the filenames it will come out with another table as you see. It's seems AA has it's one filename sorting. Expecting a numeric value in the file name. Report_Pacman_Reverse.JPG So I still want to know, what...

Hi' After a preprocessing with 20 frames of Pacman I get a Report I get a table where I can see the sky getting darker as time goes by : But how is this, to be read. What is the Y axe with a value of 2190 ? Can I translate it into a Bortle value https://en.wikipedia.org/wiki/Bortle_scale Report_Pacm...

So I only use Lights 30x180 sec. :) My set up give me 1" / pix so i tryed ...

Thanks again Iver Yes that was what I found in the manual. Nothing about sigma+sum. I am using dithering so my gees is the best is sigma. Remove hot pix and trails. Sum as I think about it should increase SNR. But it says for 8bit files. I think my cr2 files are 16bit. My result with sigma + sum are...

I cant find it in the manual.
But then it must be Sigma for rejection and Sum for SNR

Thank You Iver

Hi' I had read a lot of preprocessing with
Sigma + Sum.
But I can't find the function In the manual.
So how to do a sigma + sum?

Thank you
Oki I hope to find my lens, and try a terrestrial test.
I was hoping AA had some auto recognition like others.
