Stacking is crazy!

You might also like to give Microsoft Ice research software a try, its drag and drop, its also free and produces excellent results.

To work out the clarity you will get with a given number of stacked frames DetailMan gave me the following formula a couple of years back:

final iso = iso/(sqrt(number of frames))

So 4 frames halves the iso in terms of clarity, 16 frames quarters it and so on.

Best to you.
