merging program that doesn't warp/ rescale image series?

Took a series of lunar eclipse images, but since my FOV was too large
for a single capture, I imaged the top and bottom moon halves with my
DSLR with the hope of merging them later. Problem is that the merging
program is rescaling/ warping the images in order to merge so that my
goal of creating an animation is not met. I am using Autopano Giga. Is
there a way to merge without warping and keeping all images and moon the
same size with this program? If not, is there a program that will do
it? I'm looking at merging 400 images so I end up with 200 merged lunar
images. thanks
