It isn't free but Affinity Photo does Panorama Stitching very well, also focus stacking, and is very easy to use for this purpose. It will stitch a large number of photos all in one process which is very easy to use. It's a one time fee of $50, on sale for $40 at times (might be on Black Friday?), updates are all free, and there is a free trial period. It's a very full featured photo editing program.
