Align_image_stack is very slow as it is not properly "optimized". CPfind
itself has approximately the same speed as panomatic.

Anyway, I don't understand why you run align_image_stack in combination with
cpfind, and not with panomatic?

align_image_stack does something completely different from cpfind and
panomatic, either you use it with both or not at all.

The situations where you want to run align_image_stack is when the images in
your panorama are sets of images with different exposure that you want to
align first, then (en)fusing them and then (en)blend the fused images to a
panorama. In that case you run align_image_stack before cpfind or panomatic
or autopano-sift-c.
